Onions

From the family Liliaceae

These plants are widely distributed throughout the world. The onion goes back to a time before historians, and has been in cultivation so long that its country of origins are now uncertain although most agree that it originated in Central Asia. It was probably introduced to Europe by the Romans. The name seems to have been derived from the Latin word 'unio' meaning a large pearl.

In the middle Ages it was believed that a bunch of onions hung outside the door would absorb the infection of the plague, saving the inhabitants. From this came the scientific recognition that its sulphur content acts as a strong disinfectant. The juice of the onion was used to heal gunshot wounds and burns caused by gunpowder.

Species

There are many, many varieties of Onion; the following information concerns the two that have herbal qualities.

Allium fistulosum

Welsh Onion

Also known as Japanese Leek. Evergreen hardy perennial. Ht60cm-90cm (2-3ft). Flowers of second year's growth greenish yellow in early summer. Leaves, green hollow cylinders. This onion is a native of Siberia and extensively grown in China and Japan. The name Welsh comes from 'walsch' meaning foreign.

Allium cepa Proliferum Group

Tree Onion

Also known as Egyptian Onion, Lazy Man's Onions. Hardy perennial. Ht 90- 150cm (3-5ft). Flowers small greenish white appear in early summer in the same place as its bulbs. It grows bulbs underground and then, at the end of flowering, bulbs in the air. Seeing is believing. It originates from Canada. It is very easy to propagate.

Cultivation

Propagation

Seed

Welsh onion seed loses its viability within 2 years, so sow fresh in late winter, early spring under protection with a bottom heat of between 15°C (60°F) and21°C (70°F). Cover with Perlite. When the seedlings are large enough, and after a period of hardening off, plant out into a prepared site in the garden at a distance of 25cm (9in) apart. The tree onion is not grown from seed.

Division

Each year the Welsh onion will multiply in clumps, so it is a good idea to divide them every 3 years in the spring. Because the tree onion is such a big grower, it is a good idea to split the underground bulbs every 3 years in spring.

Bulbs

The air growing bulbils of the tree onion have small root systems, each one capable of reproducing another plant. Plant where required in an enriched soil either in the autumn, as the parent plant dies back, or in the spring.

Pests and Diseases

The onion fly is the curse of the onion family especially in late spring, early summer. The way to try and prevent this is to take care not to damage the roots or leaves when thinning the seedlings and also not to leave the thinning lying around, the scent attracts the fly.

Another problem is downy mildew caused by cool wet autumns; the leaves become velvety and die back. Again, too warm a summer may encourage white rot. Burn the affected plants and do not plant in the same position again.

Other characteristic diseases are neck rot and bulb rot, both caused by a Botrytis fungus that usually occurs as a result of the bulbs being damaged either by digging or hoeing.

Onions are prone to many more diseases but, if you keep the soil fertile and do not make life easy for the onion fly, you will still have a good crop.

Maintenance

Spring: Sow the seed; divide 3-year-old clumps of Welsh and tree onions. Plant bulbs of tree onions.

Summer: Stake mature tree onions to stop them falling over and depositing the ripe bulbils on the soil.

Autumn: Mulch around tree onion plants with well-rotted manure. Use a small amount around the Welsh onions.

Winter: Neither variety needs protection.

Garden Cultivation

Welsh Omens

These highly adaptable hardy onions will grow in any well-drained fertile soil. Seeds can be sown in spring after the frosts, direct into the ground. Thin to a distance of 25cm (9in) apart. Keep well watered throughout the growing season. In the autumn give the area a mulch of well-rotted manure.

Tree Onions

Dig in some well-rotted manure before planting. Plant the bulbs in their clusters in a sunny well-drained position at a distance of 30-45cm (12-18in) apart. In the first year nothing much will happen (unless you are one of the lucky ones). If the summer is very dry, water well. In the following year, if you give the plant a good mulch of well-rotted manure in autumn, it grows to 90-150cm (3-5ft) and produce masses of small onions.

Harvest

Welsh onions may be picked at any time from early summer onwards. The leaves do not dry well but can be frozen like those of their cousin, chives. Use scissors and snip them into a plastic bag. They form neat rings; freeze them.

The little tree onions can be picked off the stems and stored; lay them out on a rack in a cool place with good ventilation.

Culinary

Welsh onions make a great substitute for spring onions, as they are hardier and earlier. Pull and use in salads or stir fry dishes, chop and use instead of chives.

Tree onions provide fresh onion flavor throughout the year. The bulbils can be pickled or chopped raw in salads (fairly strong), or cooked whole in stews and casseroles.

Pissaladiere

Serves 4-6

4 tablespoons olive oil (not extra virgin)

20 tree onions, finely chopped

1 clove garlic, crushed

1 dessertspoon fresh thyme, chopped

Salt

Freshly ground black pepper 360g (¾ lb) once-risen bread dough

250g (½ lb) ripe tomatoes, peeled and sliced

60g (2oz) canned anchovy fillets, drained and halved lengthways

16 large black olives, halved and pitted

Heat the olive oil in a heavy frying pan, add the onions, cover the pan tightly and fry, gently stirring occasionally for 15 minutes. Add the garlic and the thyme and cook uncovered for 15 minutes, or until the onions are reduced to a clear puree. Season to taste and leave to cool. Pre-heat the oven to 200°C (400°F, Gas mark 6).

Roll the bread dough directly on the baking sheet into a circle 25cm (10in) diameter. Spread the pureed onions evenly over the dough, put the tomato slices on the onions and top with a decorative pattern of anchovy fillets and olives.

Bake for 5 minutes. Reduce the oven temperature to 190°C (375°F, Gas mark 5) and continue to bake for 30 minutes or until the bread base is well risen and lightly browned underneath. Serve hot with a green herb salad.

Other uses

The onion is believed to help ward off colds in winter and also to induce sleep and cure indigestion. The fresh juice is antibiotic, diuretic, expectorant, antispasmodic, so useful in the treatment of coughs, colds, bronchitis, laryngitis and gastroenteritis. It is also said to lower the blood pressure and to help restore sexual potency which has been impaired by illness or mental stress.

Container growing

Welsh onions can be grown in a large pot using a soil-based compost, and make sure it does not dry out. Feed regularly throughout the summer with a liquid fertilizer. Tree onions grow too tall for containers.

Lady’s Mantle

From the family Rosaceae

Lady's mantle is a native of the mountains of Europe, Asia and America. It is found not -A only in damp places but also in dry shady woods.

The Arab 'alkemelych' (alchemy) was thought to be the source of the herb's Latin generic name, Alchemilla. The crystal dew lying in perfect pearl drops on the leaves have long inspired poets and alchemists, and was reputed to have healing and magical properties, even to preserve a woman's youth provided she collected the dew in May, alone, in full moonlight, naked, and with bare feet as a sign of purity and to ward off any lurking forces.

In the medieval period it was dedicated to the Virgin Mary, hence Lady's Mantle was considered a woman's protector, and nicknamed 'a woman's best friend', and was used not only to regulate the menstrual cycle and to ease the effects of menopause, but also to reduce inflammation of the female organs. In the 18th century, women applied the leaves to their breasts to make them recover shape after they had been swelled with milk. It is still prescribed by herbalists today.

Alchemilla conjuncta

Lady's Mantle Conjuncta Hardy perennial. Ht 30cm (12in), spread 30cm (12in) or more. Tiny, greenish-yellow flowers in summer. Leaves star-shaped, bright green on top with lovely silky silver hairs underneath. An attractive plant suitable for ground cover, rockeries and dry banks.

Species

Alchemilla alpina

Alpine Lady's Mantle Known in America as Silvery Lady's Mantle. Hardy perennial. Ht 15cm (6in), spread 60cm (24in) or more. Tiny, greenish-yellow flowers in summer. Leaves rounded, lobed, pale green and covered in silky hairs. An attractive plant suitable for ground cover, rockeries and dry banks.

Alchemilla mollis

Lady's Mantle (Garden variety) Hardy perennial. Ht and spread 50cm (20in). Tiny, greenish-yellow flowers in summer. Large, pale green, rounded leaves with crinkled edges.

Alchemilla xanthochlora (vulgaris)

Lady's Mantle (Wildflower variety) Also known as Lion's Foot, Bear's Foot and Nine Hooks. Hardy perennial. Ht 15-45cm (6-18in), spread 50cm (20in). Tiny, bright greenish/yellow flowers in summer. Round, pale green leaves with crinkled edges.

Cultivation

Propagation

Seed

Why is it that something that self-seeds readily around the garden can be so difficult to raise from seed? Sow its very fine seed in early spring or autumn into prepared seed or plug trays (use the cardboard method), and cover with Perlite. No bottom heat required. Germination can either be sparse or prolific, taking 2-3 weeks. If germinating in the autumn, winter seedlings in the trays and plant out the following spring when the frosts are over, at a distance of 45cm (18in) apart.

Division

All established plants can be divided in the spring or autumn. Replant in the garden where desired.

Pests and Diseases

This plant rarely suffers from pests or disease.

Maintenance

Spring: Divide established plants. Sow seeds if necessary. Summer: To prevent self-seeding, cur off flower heads as they begin to die back. Autumn: Divide established plants if necessary. Sow seed. Winter: No need for protection.

Garden Cultivation

This fully hardy plant grows in all but boggy soils, in sun or partial shade. Seed can be sown in spring where you want the plant to flower. Thin the seedlings to 30cm (12in) apart. This is a most attractive garden plant in borders or as an edging plant, but it can become a bit of a nuisance, seeding everywhere. To prevent this, cut back after flowering and at the same time cut back old growth.

Harvest

Cut young leaves after the dew has dried for use throughout the summer. Harvest for drying as plant comes into flower.

Container Growing

All forms of Lady's Mantle adapt to growing and look very pretty indeed. Use a (following manufacturer's instructions) only occasionally. In the winter, when the plant dies back, put the container in a cold greenhouse or cold frame, and water only very occasionally. Lady's Mantle can be grown in hanging baskets as a centre piece.

Medicinal

Used by herbalists for menstrual disorders. It has been said that if you drink an infusion of green parts of the plant for 10 days each month it will help relieve menopausal discomfort. It can also be used as a mouth rinse after tooth extraction. Traditionally, the alpine species has been considered more effective, although this is not proven.

Culinary

Tear young leaves, with their mild bitter taste, into small pieces and toss into salads. Many years ago Marks & Spencer had a yoghurt made with Lady's Mantle leaves! I wish I had tried it.

Other uses

Excellent for flower arranging. Leaves can be boiled for green wool dye and are used in veterinary medicine for the treatment of diarrhoea.

Anise Hyssop

Anise Hyssop

Also known as Giant Hyssop, Anise Hyssop, Blue Giant Hyssop, Fennel Hyssop, Fragrant Giant Hyssop. From the family Labiatae. Anise hyssop is a native of North America, the Mosquito Plant and A. mexicana 'Brittonastrum mexicana' are from Mexico, and A. rugosa is from Korea.

There are few references to the history of this lovely herb. According to Allen Paterson, Director of the Royal Botanical Garden in Ontario, it is a close cousin of the Bergamots. It is common in North American herb gardens and is certainly worth including in any herb garden for its flowers and scent. The long spikes of purple, blue and pink flowers are big attractions for bees and butterflies.

Species

Agastache cana

The Mosquito Plant Hall-hardy perennial. Ht 60cm (2ft), spread 30cm (1ft). Pink tubular flowers in the summer with aromatic oval mid-green toothed leaves.

Agastache mexicana 'Brittonastrum mexicana' (or 'Cedronella mexican')

Half-hardy perennial. Ht 1m (3ft), spread 30cm (1ft). In summer whorls of small tubular flowers in shades from pink to crimson. Leaves oval pointed, toothed and mid-green with an eucalyptus scent.

Agastache rugosa

Korean Mint Hardy perennial. Ht lm (3ft), spread 30cm (1ft). Lovely mauve/purple flower spikes in summer. Distinctly minty scented mid-green oval pointed leaves.

Agastache foeniculum

Anise Hyssop Hardy perennial. Ht 60cm (2ft), spread 30cm (1ft). Long purple flower spikes in summer. Aniseed scented mid-green oval leaves.

Container Growing

Not suitable for growing indoors. However, anise hyssop and Korean mint both make good patio plants provided the container is at least 25- 30cm (10-12in) diameter. Use the bark, peat mix of compost, and a liquid fertilizer feed only once a year after flowering. If you feed the plant beforehand, the flowers will be poor. Keep well watered in summer.

Cultivation

Propagation

A. mexicana can only be propagated by cuttings.

Seed

The small fine seeds need warmth to germinate: 17°C (65°F). Use the cardboard method and artificial heating if sowing in early spring.

Use either prepared seed or plug trays or if you have only a few seeds directly into a pot and cover with Perlite. Germination takes 10-20 days.

One can also sow outside in the autumn when the soil is warm, but the voting plants will need protection throughout the winter months.

When the seedlings are large enough to handle prick out and pot on using a bark or peat mix of compost. In mid-spring, when air and soil temperature has risen, plant out al a distance of 45cm (18in).

Cuttings

Take cuttings of soft young shoots in spring: when all the species root well. Use 50pei cent bark, 50per cent peat mix of compost. After a full period of weaning cuttings should be strong enough to plant out in the early autumn.

Semi-ripe wood cuttings may be taken in late summer, use the same compost mix. After they have rooted, pot up, and winter in a cold frame or cold greenhouse.

Division

This is a good alternative way to maintain a short-lived perennial. In the second or third year divide the creeping roots either by the 'forks back-to-back' method, or by digging up the whole plant and dividing.

Pests and Diseases

Being an aromatic plant, pests keep their distance. Rarely suffers from disease, although seedlings can damp off.

Maintenance

Spring: Sow seeds. Summer: Take softwood or semi-ripe cuttings late season.

Autumn: Tidy up the plants by cutting back the old flower heads and woody growth. Sow seeds. Protect young plants from frost. Winter: Protect half-hardy species (and Anise hyssop below -6°C (20°F)) with either agricultural fleece, bark or straw.

Garden Cultivation

All species like a rich, moist soil and full sun, and will adapt very well to most ordinary soils if planted in a sunny situation. All are short lived and should be propagated each year to ensure continuity.

Anise hyssop, although hardier than the other species, still needs pro-lection below-6°C (20°F).

The Mexican half-hardy species need protection below -3°C (26°F).

Harvest

Flowers

Cut for drying just as they begin to open.

Leaves

Cut leaves just before late spring flowering

Seeds

Heads turn brown as the seed ripens. At the first sign of the seed falling, pick and hang upside down with a paper bag tied over the heads.

Other uses

Anise Hyssop, Korean Mini and Agastache mexicana all have scented leaves which makes them suitable for potpourris.

Culinary

Anise Hyssop

Leaves can be used in salads and to make refreshing tea. Like borage, they can be added to summer fruit cups. Equally they can be chopped and used as a seasoning in pork dishes or in savory rice.

Flowers can be added to fruit salads and cups giving a lovely splash of color.

Korean Mint

Leaves have a strong peppermint flavor and make a very refreshing tea, said to be good first thing in the morning after a night on the town. They are also good chopped up in salads, and the flowers look very attractive scattered over a pasta salad.

Chamomile

Chamomile From the Family Compositae

Chamomile grows wild in Europe, North America, and many other countries. As a garden escapee, it can be found in pasture and other grassy places on sandy soils.

The generic name, Chamaemelum, is derived from the Greek Khamaimelon, meaning 'Earth Apple' or 'apple on the ground'.

Species

Chamaemelum nobile

Roman Chamomile

Also known as Garden Chamomile, Ground Apple, Low Chamomile and Whig Plant Hardy perennial evergreen. Ht 10cm (4in), spread 45cm (18in). White flowers with yellow centres all summer. Sweet smelling, finely divided foliage. Ideal for ground cover. Can be used as a lawn, but because it flowers it will need constant cutting.

Chamaemelum nobile 'Flore Pleno'

Double-flowered Chamomile

Hardy perennial evergreen. Ht 8cm (3in), spread 30cm (12in). Double white flowers all summer. Sweet-smelling, finely divided, thick foliage. Good for ground cover, in between paving stones and lawns. More compact habit than Roman Chamomile, and combines well with Chamomile Treneague.

Chamaemelum nobile 'Treneague' (Anthemis nobilis Treneague')

Chamomile Treneague

Also known as Lawn Chamomile Hardy perennial evergreen. Ht 6cm (2.5in), spread 15cm (6in). Non-flowering. Leaves are finely divided and very aromatic. Ideal for ground cover or mow-free lawn. Plant in well-drained soil, free from stones, 10-15cm (4-6in) apart.

Anthemis tinctoria

Dyers Chamomile

Also known as Yellow Chamomile Hardy perennial evergreen. Ht and spread lm (3ft). Yellow daisy flowers in the summer. Leaves are mid-green and fern like. Principally a dye plant.

Matricaria recutita

German Chamomile

Also known as Scented Mayweed, Wild Chamomile Hardy annual. Ht 60cm (24in), spread 10cm (4in). Scented white flowers with conical yellow centres from spring to early summer. Finely serrated aromatic foliage. The main use of this chamomile is medicinal.

Cultivation

Propagation

Seed

Dyers, Roman and German chamomiles can be grown from seed. Sow onto the surface of a prepared seed or plug tray. Use a bark, grit, peat compost. Cover with Perlite. Use bottom heat 19°C (65°F). Harden off and plant out or pot on.

Cuttings

Double-flowered chamomile and Chamomile Treneague can only be propagated this way. Take cuttings in the spring and autumn from the offsets or clusters of young shoots. They are easy to grow as they have aerial roots.

Division

All perennial chamomiles planted as specimen plants will benefit from being lifted in the spring of their second or third year and divided.

Pests and Diseases

As all the chamomiles are j highly aromatic they are not troubled by pests or disease.

Maintenance

Spring: Collect offshoots, sow seeds. Fill in holes that have appeared in the chamomile lawn. Divide established plants. Give a liquid fertilizer feed to all -established plants.

Summer: Water well. Do not allow to dry out. In the first season of a lawn, trim the plants to encourage bushing out and spreading. In late summer collect flowers from the Dyers chamomile and cut the plant back to 6cm (2in) to promote new growth.

Autumn: Take cuttings. Divide if they have become too invasive. Cut back to promote new growth. Give the final Iced of the season.

Winter: Only protect in extreme weather

Garden Cultivation

All the chamomiles prefer a well-drained soil and a sunny situation, although they will adapt to most conditions.

As a lawn plant, chamomile gets more credit than it deserves. Chamomile lawns are infinitely less easy to maintain in good condition than grass lawns. There is no selective herbicide that will preserve chamomile and kill the rest of the weeds. It is a hands-and-knees job.

Prepare the site well, make sure the soil is light, slightly acid, and free from weeds and stones. Plant young plants in plug form. I use a mix of double-flowered and Treneague chamomile at a distance of 10-15cm (4-6in) apart. Keep all traffic off it for at least 12 weeks, and keep it to the minimum during the first year.

If all this seems daunting, compromise and plant a chamomile seat. Prepare the soil in the same way and do not sit on the seat for at least 12 weeks. Then sit down, smell the sweet aroma and sip a cool glass of wine. Summer is on hand . . .

Harvest

Leaves

Gather in spring and early summer for best results. Use fresh or dry.

Flowers

Pick when fully open, around mid-summer. Use fresh or dry. Dyers chamomile flowers should be harvested in summer for their yellow dye.

Companion planting

Chamomile has the unique name Physician's Plant because, when planted near ailing plants, it helps to revive them. Roman Chamomile can be planted next to onions to repel flying insects and improve the crop yield.

Chamomile Infusion

Bring 600ml (1 pint) water to the boil. Add a handful of chamomile leaves and flowers. Cover and let it stand for about half a day Strain.

Spray it onto seedlings to prevent 'damping off. If there is any liquid left pour it onto your compost heap. This acts like an activator for decomposition.

Container growing

I would not advise growing chamomiles indoors, as they get very leggy, soft and prone to disease. But the flowers can look very cheerful in a sunny window box. Use Chamomile 'Flore Pleno', which has a lovely double flower head or the non-flowering C. Treneague as an infill between bulbs, with a bark, grit, peat compost.

Cosmetic

Chamomile is used as a final rinse for fair hair to make it brighter. It should be poured over your hair several times. Pour 1 liter (l34 pints) boiling water over one handful of chamomile flowers and steep for 30 minutes. Strain, rover and allow to cool.

Medicinal

German chamomile's highly scented dry flower heads contain up to 1 per cent of an aromatic oil that possesses powerful antiseptic and anti-inflammatory properties. Taken as a tea, it promotes gastric secretions and improves the appetite, while an infusion of the same strength can be used as an internal antiseptic. It may also be used as a douche or gargle for mouth ulcers and as an eye wash.

Oil for skin rashes or allergies can be made by tightly packing flower heads into a preserving jar, covering with olive oil and leaving in the sun for three weeks. If you suffer from overwrought nerves, add five or six drops of chamomile oil to the bath and this will help you relax at night.

Chamomile tea

1 heaped teaspoon chamomile flowers (dried or fresh)

1 teaspoon honey slice of lemon (optional)

Put the chamomile flowers into a warm cup. Pour on boiling water. Cover and leave to infuse for 3-5 minutes. Strain and add the honey and lemon, if required. Can be drunk either hot or cold.

Other uses

Dyers Chamomile can be used as a dye plant. Depending on the mordant, its color can vary from bright to olive/brown yellow.

German and Double-flowered Chamomile are best for herb pillows and pot pourri.
