The leaves are used as an aphrodisiac[218]. Administered orally, the leaf extract increases the frequency of copulation in animals[218].

Cultivation details

Landscape Uses:Border, Container, Ground cover, Rock garden, Woodland garden. Succeeds in any fertile humus-rich soil[200], preferring a moist but well-drained peaty loam[1, 280]. Requires a lime-free soil[280]. Grows best in the light dappled shade of a woodland[200, 280]. Plants can succeed in the dry shade of trees[233]. A shallow-rooting plant, the rhizomes creeping just below the soil and the finer roots occupying the top 30cm of the soil[280]. A clump-forming species, the rhizomes making only short new growth each year, it needs to be divided every 3 - 4 years in order to maintain vigour[280]. Plants are hardy to about -20°c[187], though the flowers in spring can be damaged by late frosts[233]. A very ornamental plant[1], there are several named varieties[187]. It grows well in the rock garden or wild garden[1]. Plants are self-sterile and so more than one clone is required for cross-fertilization in order for seed to be produced. Plants will often hybridise with other species growing nearby[280]. Members of this genus are rarely if ever troubled by browsing deer or rabbits[233]. Special Features: Attractive foliage, Naturalizing.

Propagation

Seed - best sown in a cold frame as soon as it is ripe in late summer[200, 280]. 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, best carried out in August to September according to one report[280], in late spring according to another[200]. 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[200].

If this herb increases the weight of the prostate gland, then 1) On cessation of its use, will the weight return to normal. 2) Is the weight increase likely to be detremental in the future, especially in middle age and beyond in relation to prostate problems for men.
