Botanical Name: Potentilla kleiniana
Family: Rosaceae
Subfamily: Rosoideae
Genus: Potentilla
Species: Potentilla kleiniana
Kingdom: Plantae
Order: Rosales

Synonyms: Potentilla reptans. A. Gray. Duchesnea sundaica.

Habitat : Potentilla kleiniana is native to E. Asia – China, Japan, India. It grows on grass thickets, field edges, roadsides and gardens. Field sides, meadows and grassland on mountain slopes at elevations of 400 – 3000 metres in China.

Description:
Potentilla kleiniana is a annual, biennial, or perennial herb, growing to 0.3 m (1ft). Flowering stems prostrate or ascending, 10–50 cm tall, together with petioles pilose or spreading villous, usually rooting at nodes and developing new plants. Radical leaves 3–20 cm including petiole; stipules tinged brown, membranous, abaxially pilose or glabrescent; leaf blade subpedately 5-foliolate; leaflets subsessile or shortly petiolulate, both surfaces green, obovate or oblong-obovate, 0.5–4 × 0.4–2 cm, both surfaces pilose, abaxially densely appressed villous on veins, adaxially sometimes glabrescent, base cuneate, margin acutely or obtusely many serrate, apex obtuse; lower cauline leaves 5-foliolate, upper ones 3-foliolate; stipules green, ovate or ovate-lanceolate, herbaceous, abaxially sparsely villous, margin entire, rarely acutely or acuminately 1- or 2-serrate; petiole gradually shorter higher up stem; leaflets resembling those of radical leaves. Inflorescence terminal, cymose, congested, pseudoumbellate. Flowers 0.8–1 cm in diam.; pedicel 1–1.5 cm, densely spreading villous, bracteate. Sepals triangular-ovate, apex acute or acuminate; epicalyx segments lanceolate or elliptic-lanceolate, shorter than sepals at anthesis, nearly equaling or slightly longer than sepals in fruit, abaxially pilose, apex acute or acuminate. Petals yellow, obovate, longer than sepals, apex emarginate. Style subterminal, conic, base thickened; stigma dilated. Achenes subglobose, flattened on 1 side, ca. 0.5 mm in diam., rugose.
It is in flower from May to September, and the seeds ripen from May to September.

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 and prefers well-drained soil. Suitable pH: acid, neutral and basic (alkaline) soils. It can grow in semi-shade (light woodland) or no shade. It prefers moist soil.

Cultivation:
We have very little information on this species and do not know if it will be hardy in Britain, though judging by its native range it should succeed outdoors in most parts of the country. The following notes are based on the general needs of the genus. Easily grown in a well-drained loam, preferring a position in full sun but tolerating shade. Prefers an alkaline soil but tolerates a slightly acid soil. 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:.…Young leaves and stems – cooked. Fruit – raw or cooked.

Medicinal Uses:

Astringent; Depurative; Febrifuge.

The plant is astringent, depurative and febrifuge. The whole plant is decocted and used in the treatment of colds, influenza, sore throat etc

Crataegus altaica

It is not frost tender. The flowers are hermaphrodite (have both male and female organs) and are pollinated by Midges.Suitable for: light (sandy), medium (loamy) and heavy (clay) soils and can grow in heavy clay soil. Suitable pH: acid, neutral and basic (alkaline) soils. It can grow in semi-shade (light woodland) or no shade. It prefers moist or wet soil and can tolerate drought. The plant can tolerates strong winds but not maritime exposure.
It can tolerate atmospheric pollution.
Cultivation:
A very easily grown plant, it prefers a well-drained moisture retentive loamy soil but is not at all fussy. Once established, it succeeds in excessively moist soils and also tolerates drought. It grows well on a chalk soil and also in heavy clay soils. A position in full sun is best when plants are being grown for their fruit, they also succeed in semi-shade though fruit yields and quality will be lower in such a position. Most members of this genus succeed in exposed positions, they also tolerate atmospheric pollution. Seedling trees take from 5 – 8 years before they start bearing fruit, though grafted trees will often flower heavily in their third year. The flowers have a foetid smell somewhat like decaying fish. This attracts midges which are the main means of fertilization. When freshly open, the flowers have more pleasant scent with balsamic undertones. This species is closely related to C. wattiana. Hawthorns in general hybridize freely with other members of the genus. Seedlings should not be left in a seedbed for more than 2 years without being transplanted.
Propagation:
Seed – this is best sown as soon as it is ripe in the autumn in a cold frame, some of the seed will germinate in the spring, though most will probably take another year. Stored seed can be very slow and erratic to germinate, it should be warm stratified for 3 months at 15°c and then cold stratified for another 3 months at 4°c. It may still take another 18 months to germinate. Scarifying the seed before stratifying it might reduce this time. Fermenting the seed for a few days in its own pulp may also speed up the germination process. Another possibility is to harvest the seed ‘green’ (as soon as the embryo has fully developed but before the seedcoat hardens) and sow it immediately in a cold frame. If timed well, it can germinate in the spring. If you are only growing small quantities of plants, it is best to pot up the seedlings as soon as they are large enough to handle and grow them on in individual pots for their first year, planting them out in late spring into nursery beds or their final positions. When growing larger quantities, it might be best to sow them directly outdoors in a seedbed, but with protection from mice and other seed-eating creatures. Grow them on in the seedbed until large enough to plant out, but undercut the roots if they are to be left undisturbed for more than two years.
Edible Uses:
Fruit – raw or cooked. About 8mm in diameter, the fruit is yellow with a fairly dry mealy texture and a pleasantly sweet flesh. The fruit can also be used in making pies, preserves, etc, and can also be dried for later use. The fruit ripens in August, making it one of the earliest ripening hawthorns. There are up to five fairly large seeds in the centre of the fruit, these often stick together and so the effect is of eating a cherry-like fruit with a single seed.
Medicinal Uses:
Although no specific mention has been seen for this species, the fruits and flowers of many hawthorns are well-known in herbal folk medicine as a heart tonic and modern research has borne out this use. The fruits and flowers have a hypotensive effect as well as acting as a direct and mild heart tonic. They are especially indicated in the treatment of weak heart combined with high blood pressure. Prolonged use is necessary for it to be efficacious. It is normally used either as a tea or a tincture.

Other Uses: Wood – heavy, hard, tough, close-grained. Useful for making tool handles, mallets and other small items.
