Epimedium koreanum (common name: korean epimedium)
Propagation: Seed - best sown in a cold frame as soon as it is ripe in late summer[1]. Sow stored seed as early as possible in the year in a cold frame. Prick out the seedlings into individual pots when they are large enough to handle and grow them on in light shade in the cold frame or greenhouse for at least their first winter[K]. Plant them out in mid to late summer[K].
Division in July/August according to one report, in late spring according to another[1]. 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.
Cuttings in late summer[1].
Cultivation: We have very little information on this species and do not know if it will be hardy in Britain. However, judging by its native range, it is likely to succeed outdoors in most areas of the country. The following notes are based on the general needs of the genus.
Succeeds in any fertile humus-rich soil[1], preferring a peaty loam[2]. Grows best in semi-shade[1]. Plants can succeed in the dry shed of trees[3].
Members of this genus are rarely if ever troubled by browsing deer or rabbits[3].
Range: E. Asia - Korea.
Habitat: Wet areas in forests and mountain valleys[4].
Medicinal: The aerial parts of the plant contain several medicaly active constituents including flavonoids and phytosteroids[4]. They are used in Korea in the treatment of spermatrrhoea, impotence and forgetfulness[4].
This plant is related to Epimedium grandiflorum, and contains a similar range of bioactive constituents. The uses of that plant are as follows:-
The aerial parts of the plant are antiasthmatic, antibacterial, antirheumatic, antitussive, aphrodisiac, hypoglycaemic, tonic and vasodilator. Its use lowers blood sugar levels[5][6]. It is used in the treatment of impotence, seminal emissions, lumbago, arthritis, numbness and weakness of the limbs, hypertension and chronic bronchitis[6]. It has an action on the genitals similar to the male sex hormone and can increase the weight of the prostate gland and seminal vesicle, it has increased copulation in animals and increases the secretion of semens[6].
The leaves are used as an aphrodisiac[7]. Administered orally, the leaf extract increases the frequency of copulation in animals[7].
Soil: Can grow in light, medium, and heavy soils.
