Botanical Name: Lavatera arborea
Family: Malvaceae
Genus: Lavatera
Species: L. arborea
Kingdom: Plantae
Order: Malvales

Common Names: Malva arborea, or, more recently as Malva eriocalyx, The tree mallow

Habitat:  Lavatera arborea is native to the coasts of western Europe and the Mediterranean region, from the British Isles south to Algeria and Libya, and east to Greece.It tolerates sea water to varying degrees, at up to 100% sea water in its natural habitat, excreting salt through glands on its leaves. This salt tolerance can be a competitive advantage over inland plant species in coastal areas. Its level of salinity tolerance is thought to be improved by soil with higher phosphate content, making guano enrichment particularly beneficial
Description:
Lavatera arborea is a shrubby annual, biennial or perennial plant growing to 0.5–2 m (rarely 3 m) tall. The leaves are orbicular, 8–18 cm diameter, palmately lobed with five to nine lobes, and a coarsely serrated margin. The flowers are 3–4 cm diameter, dark pink to purple and grow in fasciculate axillary clusters of two to seven. It grows mainly on exposed coastal locations, often on small islands, only rarely any distance inland….CLICK & SEE THE PICTURES

Although long considered a species of Lavatera, genetic and morphological analysis by Martin Forbes Ray, reported in 1998, suggested it was better placed in the genus Malva, in which it was named Malva dendromorpha M.F.Ray. However the earlier name Malva arborea L. (Webb & Berthol.) was validly published and has priority over Malva dendromorpha.

Cultivation:
An easily grown plant, succeeding in any ordinary garden soil in sun or partial shade. Prefers a light well-drained moderately fertile soil in full sun. A soil that is too rich encourages foliar growth at the expense of flowering. Tolerates maritime exposure. Plants are very fast-growing and often flower in their first year from seed. They flower so freely in their second year that they normally die afterwards, though they sometimes perennate. When well sited, this species usually self-sows freely. There are some named forms developed for their ornamental value.

Propagation:
Seed – sow late summer in situ[200]. The seed should germinate within 4 weeks.

Edible Uses: Young leaves – raw or cooked. A mild flavour, but the leaves are dry and hairy and not that agreeable in quantity on their own[K]. They can be used as part of a chopped mixed salad.
Medicineal Uses:
The leaves of the species are used in herbal medicine to treat sprains, by steeping them in hot water and applying the poultice to the affected area. It is theorised that lighthouse keepers may have spread the plant to some British islands for use as a poultice and to treat burns, an occupational hazard. Thought to have been used as an alternative to toilet paper. The seeds are edible and are known in Jersey as “petit pains”, or “little breads”.
Other Uses:
Tree mallow was considered a nutritive animal food in Britain in the 19th century, and is still sometimes used as animal fodder in Europe.

Lavatera arborea has long been cultivated in British gardens, as described in the 1835 self-published book British Phaenogamous Botany, which used the then-common name Sea Tree-mallow: “This species is frequently met with in gardens, where, if it is allowed to scatter its seeds, it will spring up for many successive years, and often attain a large size. The young plants will, as Sir J. E. Smith observes, now and then survive one or more mild Winters; but having once blossomed it perishes.”

While sometimes detrimental to seabird habitat, management of tree mallow (both planting and thinning) has been successfully employed to shelter nesting sites of the threatened roseate tern, which requires more coverage than common terns to impede predation.

[amazon_link asins=’B072296BTW,B01LXXWOQB,B0006MQ31M,B074HS99WX,B076NHSHD6,B076VPJ1QS’ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’420e61e1-cc78-11e7-a73a-e31e3a7af8c4′]

Botanical Name: Lamium Galeobdolon
Family:    Lamiaceae
Genus:    Lamium
Species:    L. galeobdolon
Kingdom:    Plantae
Order:    Lamiales

Synonyms:  Yellow Archangel. Weazel Snout. Dummy Nettle.

Common Names: Yellow Archangel , Artillery plant, or Aluminium plant

Habitat: : Lamium Galeobdolon is a widespread wildflower in Europe, and has been introduced elsewhere as a garden plant. It  grows in woods and shady hedgerows, usually on heavier soils. Sometimes becoming locally dominant, especially after coppicing.

Description:
Yellow archangel is a large-leaved perennial plant with underground runners growing to a height of about 40 to 80 cm (16 to 31 in). The paired opposite leaves are stalked, broadly ovate with a cordate base and toothed margin. The underside of the leaves is often purplish. The flowers grow in whorls in a terminal spike. The calyx is five-lobed. The corolla is yellow, 15 to 25 mm (0.6 to 1.0 in) long, the petals fused with a long tube and two lips. The upper lip is hooded and the lower lip has three similar-sized lobes with the central one being triangular and often streaked with orange. There are two short stamens and two long ones. The carpels are fused and the fruit is a four-chambered schizocarp……....click & see the pictures

Cultivation:    
Landscape Uses:Ground cover, Massing, Woodland garden. A very easily grown plant, it tolerates most soils and conditions. It grows well in heavy clay soils, though it prefers a light calcareous soil. Dislikes dry soils. This species succeeds even in dense shade, growing well under trees. Once established, it can also succeed in drought conditions under the shade of trees, providing there is plenty of humus in the soil. There are at least four sub-species, L. galeobdolon montanum is the form generally found wild in Britain and it is a triploid. L. galeobdolon luteum and L. galeobdolon flavidum are both diploids. L. galeobdolon argentatum is the more rampant form, its clone ‘Variegatum’ is a commonly used ground cover plant for shady places. Plants seem to be immune to the predations of rabbits. A very invasive plant, sending out long prostrate shoots that root at intervals along the stems. Special Features: Attractive foliage, Naturalizing.

Propagation:  
Seed – usually self sows freely and should not require human intervention. When they are large enough to handle, prick the seedlings out into individual pots and plant them out in the summer. The seed can also be sown in situ as soon as it is ripe. Division in spring. Succeeds at almost any time in the growing season. Very easy, larger clumps can be replanted direct into their permanent positions, though it is best to pot up smaller clumps and grow them on in a cold frame until they are rooting well. Plant them out in the spring

Edible Uses:  Young leaves and shoots – cooked. Young flowering tips – cooked.

Medicinal Uses:
Antispasmodic;  Astringent;  Diuretic;  Expectorant;  Styptic;  Vasoconstrictor.

The herb is antispasmodic, astringent, diuretic, expectorant, styptic and vasoconstrictor.The crushed leaves bound to open sores will cause rapid healing.

Other Uses:   A good ground cover plant, spreading rapidly by means of its rooting stems and succeeding even in dense shade. It is very vigorous, however, and can smother small plants. It does very well in woodlands.
