Anthemis



Anthemis tinctoria


Anthemis rosea

Anthemis (Án-the-mis) is a genus of about 100 species of aromatic herbs in the Asteraceae, closely related to Chamaemelum, and like that genus, known by the common name Chamomile; some species are also called Dog-fennel or Mayweed. However, Mayweed is improperly used for this genus since Mayweed refers to the Matricaria genus. Anthemis are native to the Mediterranean region and southwest Asia east to Iran. They have been grown in and have become native to England/United Kingdom.Anthemis species are used as food plants by the larvae of some Lepidoptera species including Bucculatrix anthemidella, a leaf-miner which feeds exclusively on Anthemis tinctoria.

The flowers are commonly used for tea, and the leaves, when crushed, give off a scent of apples. It grows well in light, sandy soil. Nicknamed "the plants' physician", it seems to improve the health of other plants grown near it. Chamomile flowers make a good rinse for fair hair.

Anemone





Anemone (Anemone) (A-ne-mó-ne, from the Gr. Άνεμος, wind), is a genus of about 120 species of flowering plants in the buttercup family Ranunculaceae in the north and south temperate zones. They are closely related to Pasque flower (Pulsatilla) and Hepatica (Hepatica); some botanists include both of these genera within Anemone.

The plants are perennial herbs with an underground rootstock, and radical, more or less deeply cut, leaves. The elongated flower stem bears one or several, white, red, blue or rarely yellow, flowers; there is an involucre of three leaflets below each flower. The fruits often bear long hairy styles which aid their distribution by the wind ("windflower" is a common name sometimes used for members of the genus).

The Anemone coronaria ("Kalanit" in Hebrew) is one of the most well known and beloved flowers in Israel. During the British Mandate of Palestine British soldiers were nicknamed "Kalaniyot" for their red berrets

Anchusa










Anchusa officinalis Anchusa azurea

The genus Anchusa L. belongs to the tribe Boragineae of the borage family (Boraginaceae). It includes about 40 species.

These species grow in Europe, North Africa, South Africa en Western Asia. They are introduced into the USA.

They consist of annual plants, biennial plants and perennial plants with the general characteristics of the borage family. They are generally herbs, covered with bristly hairs. The leaves are simple or undulate, covered with stiff hairs.

The small radially symmetrical flowers are sapphire blue and retain their color a long time. The plants show numerous flowers with 5 sepals, untied at their base, and 5 petals forming a narrow tube facing upwards. The flowers grow in several axillary cymes, simple or branched, or are clustered at the end. The flowers are much frequented by bees.

The roots of Anchusa (just like those of Alkanna and Lithospermum) contain anchusin (or alkanet-red ), a red-brown resinoid coloring matter. It is insoluble in water, but soluble in alcohol, chloroform and ether.

Anchusa species are used as food plants by the larvae of some Lepidoptera species including Coleophora onosmella.

Anagallis foemina

Anagallis foemina

Anagallis is a genus of about 20–25 species of flowering plants in the myrsine family Myrsinaceae, commonly called pimpernel and perhaps best known for the Scarlet pimpernel referred to in literature.

These are annual or perennial plants, growing in tufts on weedy and uncultivated areas. The stems are prostrate with ovate to cordate leaves. The flowers of the different species show miscellaneous colors. They are radially symmetrical with five petals. They grow usually in the leaf axils, but sometimes as short spikes at the top of the stem. Pimpernel flowers remain open only under direct sun-light.

They were formerly classified as members of the primrose family (Primulaceae), but a genetic and morphological study by Källersjö et al. (1999; see references) showed that they belong to the Myrsinaceae. Another study by Ulrika Manns and Arne A. Anderberg (2005), based on molecular phylogeny, states the genus in its present circumscription is paraphyletic and should also include in its clade the small genera Asterolinon and Pelletiera, as well as two LysimachiaLysimachia nemorum and Lysimachia serpyllifolia).

Allium

Allium aucheri



Allium olympicum



Allium cappadocicum










Allium akaka




Allium karamanoglui









Allium is the onion genus,, with about 1250 species, making it one of the largest plant genera in the world. They are perennial bulbous plants that produce chemical compounds that give them a characteristic onion or garlic taste and odor, and many are used as food plants. Allium is classified in family Alliaceae although some classifications have included it in the lily family (Liliaceae).

Allium species occur in temperate climates of the northern hemisphere, except for a few species occurring in Chile (as Allium juncifolium), Brazil (Allium sellovianum) or tropical Africa (Allium spathaceum). They can vary in height between 5 cm and 150 cm. The flowers form an umbel at the top of a leafless stalk. The bulbs vary in size between species, from very small (around 2–3 mm in diameter) to rather big (8–10 cm). Some species (such as Welsh onion, A. fistulosum) develop thickened leaf-bases rather than forming bulbs as such.

Most bulbous alliums increase by forming little bulbs or "offsets" around the old one, as well as by seed. Several species can form many bulbils (tiny bulbs) in the flowerhead; in the so-called "tree onion" (A. cepa Proliferum Group) the bulbils are few, but large enough to be used for pickling.

Members of the genus include many valued vegetables such as onions, shallots, leeks and herbs such as garlic and chives. A strong "oniony" odor is characteristic of the whole genus, but not all members are equally flavorful.

Some Allium species, including A. cristophii and A. giganteum, are used as border plants for their flowers, and their "architectural" qualities. Several hybrids have been bred, or selected, with rich purple flowers. Allium hollandicum 'Purple Sensation' is one of the most popular and has been given an Award of Garden Merit (H4). By contrast, other species (such as the invasive Allium triquetrum) can become troublesome garden weeds.

Various Allium species are used as food plants by the larvae of some Lepidoptera including Cabbage Moth, Common Swift moth (recorded on garlic), Garden Dart moth, Large Yellow UnderwingNutmeg moth, Setaceous Hebrew Character moth, Turnip Moth and Schinia rosea, a moth which feeds exclusively on Allium spp.

Ajuga chamaepitys


Ajuga chamaepitys is a herbaceous flowering plant native to Europe. This plant is often used as medicinal and ornamental plant.

Both in foliage and blossom it is very unlike its near relative, the Common Bugle, forming a bushy, herbaceous plant, 3 to 6 inches high, the four-cornered stem, hairy and viscid, generally purplish red, being much branched and densely leafy. Except the lowermost leaves, which are lanceshaped and almost undivided, each leaf is divided almost to its base into three very long, narrow segments, and the leaves being so closely packed together, the general appearance is not altogether unlike the long, needle-like foliage of the pine, hence the plant has received a second name- Ground Pine. The flowers are placed singly in the axils of leaf-like bracts and have bright yellow corollas, the lower lip spotted with red. They are in bloom during May and June.

The whole plant is very hairy, with stiff hairs, which consist of a few long joints. It has a highly aromatic and turpentiny odour and taste.

---Uses---Ground Pine has stimulant, diuretic and emmenagogue action and is considered by herbalists to form a good remedy, combined with other suitable herbs, for gout and rheumatism and also to be useful in female disorders, an infusion of 1 OZ. of the dried herb to 1 pint of boiling water being recommended, taken in tablespoonful doses, frequently repeated.

The herb was formerly regarded almost as a specific in gouty and rheumatic affections, the young tops, dried and reduced to powder being employed. It formed an ingredient of the once famous Portland Powder.

It likewise operates powerfully by urine, removing obstructions and is serviceable in dropsy, jaundice and ague, reputed great cures having been performed by its use, either in infusion, or powder.
