Family: Rosaceae
Genus: Comarum
Species: C. palustre
Kingdom: Plantae
Order: Rosales

Synonyms: Comarum palustre

Habitat : Potentilla palustris is native to Europe, including Britain, from Iceland south and east to the Pyrenees, temperate Asia and Japan. It grows on marshes, bogs, acid fens and wet heaths.

Description:
Potentilla palustris is a perennial herb growing to 0.5 m (1ft 8in) by 1.5 m (5ft). Its branches spread into leaves with three to seven narrow leaflets which are sharply jagged. The stem is a reddish-brown, low sprawling, vine-like structure. Flowers extend from the branch which vary from red to purple, and are about one inch in diameter, blooming in summer. The stems roots at the base then rises to about 30 cm.

It is in flower from May to August. The flowers are hermaphrodite (have both male and female organs) and are pollinated by Insects.The plant is self-fertile.
Suitable for: light (sandy), medium (loamy) and heavy (clay) soils. Suitable pH: acid, neutral and basic (alkaline) soils and can grow in very acid soils.
It can grow in semi-shade (light woodland) or no shade. It prefers wet soil.
Cultivation:
Requires a moist to wet soil, preferably on the acid side. A very cold-hardy plant, tolerating temperatures down to about -25°c. A rapidly spreading plant, capable of forming clumps several metres across. It is a plant for the wild wet garden. Members of this genus are rarely if ever troubled by browsing deer.

Propagation:
Seed – sow early spring or autumn in a cold frame. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Division in spring. Larger divisions can be planted out direct into their permanent positions. We have found that it is better to pot up the smaller divisions and grow them on in light shade in a cold frame until they are well established before planting them out in late spring or early summer.
Edible Uses: Tea..…..The dried leaves are a tea substitute.

Medicinal Uses:...Astringent.
The root is astringent. A decoction has been used in the treatment of dysentery and stomach cramps.
Other Uses:..Dye; Tannin……..A red dye is obtained from the flowers. Tannin is obtained from the root.

Centaurea Scabiosa

[amazon_link asins=’B002I6V10W,B01ETYSKOU,B00ANZ45H6,B01EQ1W2FE,B00DL0I0FI,B01AD0DCEW’ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’505aebc3-c5ce-11e7-8efb-b99fb23d4568′]

Botanical Name : Centaurea Scabiosa
Family: Asteraceae
Tribe: Cynareae
Genus: Centaurea
Species: C. scabios
Kingdom: Plantae
Order: AsteralesBotanical Name : Centaurea Scabiosa

Synonyms: Hardhead. Ironhead. Hard Irons. Churls Head. Logger Head. Horse Knops. Matte Felon. Mat Fellon. Bottleweed. Bullweed. Cowede. Boltsede.

Common Name:  Greater Knapweed

Habitat: Centaurea Scabiosa is native to Europe and bears purple flower heads.
It is found growing in dry grasslands, hedgerows and cliffs on lime-rich soil.Frequent in the borders of fields and in waste places, being not uncommon in England, where it is abundant on chalk soil, but rare in Scotland. It grows in pastures, field edges and roadsides, usually on chalk.

Description:
Centaurea Scabiosa is a perennial plant, the rootstock is thick and woody in old plants. The stem is 1 to 3 feet high, generally branched, very tough. The leaves, which are firm in texture, are very variable in the degree of division, but generally deeply cut into, the segments again deeply notched. The lower leaves are very large, often a foot or even more in length, making a striking looking rosette on the ground, from which the flowering stems arise. The whole plant is a dull green, sparingly hairy. It flowers in July and August. The flowers are terminal, somewhat similar to those of the Cornflower in general shape, though larger. All the florets are of the same colour, a rich purplish-crimson, the outer ray ones with the limb divided nearly to the base into narrow, strap-shaped segments. The flower-head is hard and solid, a mass of bracts lapping over each other like tiles, each having a central green portion and a black fringe-like edge. In some districts the plant is called from these almost round heads, ‘Hardhead,’ and the ordinary English name, Knapweed, is based on the same idea, Knap, being a form of Knop, or Knob.

Cultivation:
Succeeds in ordinary garden soil. Prefers a well-drained fertile soil and a sunny position. Tolerates dry, low fertility and alkaline soils. Does well in the summer meadow. An important nectar plant for bees and butterflies. Members of this genus are rarely if ever troubled by browsing deer.

Propagation:
Seed – sow early spring in a cold frame. When they are large enough to handle, prick the seedlings out into individual pots and plant them out into their permanent positions in the summer. Division in autumn. 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 summer or following spring. This should be done at least once every three years in order to maintain the vigour of the plant. Basal cuttings in spring. Harvest the shoots when they are about 10 – 15cm long with plenty of underground stem. Pot them up into individual pots and keep them in light shade in a cold frame or greenhouse until they are rooting well. Plant them out in the summer.

Parts Used  in medicine: ––Root, seeds.

Medicinal Uses:
Diaphoretic; Diuretic; Tonic; Vulnerary.

The roots and seeds are diaphoretic, diuretic, tonic and vulnerary. The plant once had a very high reputation as an ingredient of the Medieval ‘salve’, an ointment applied to heal wounds and treat skin infections.
The root and seeds are used. Its diuretic diaphoretic and tonic properties are recognized.

It is good for catarrh, taken in decoction, and is also made into ointment for outward application for wounds and bruises, sores, etc.

Culpepper tells us: ‘it is of special use for soreness of throat, swelling of the uvula and jaws, and very good to stay bleeding at the nose and mouth.’
