Hosta clausa (1 Page of 5) The Hosta clausa plant species is found in E. Asia - Korea. It is a member of the Funkiaceae family. Cultivation | Propagation | General Uses Medicinal | Edible Uses Latin Name: Hosta clausa Family: Funkiaceae Author: Nak. Known Hazards: None known Mature Height: 0.2 Mature Width: 1 Habitat: Along the banks of rivers where it is subject to periodic inundation[251].
Cultivation Notes: Thrives in most fertile soils if they are rich in humus[200]. Grows well in heavy clay soils and in sandy ones[208]. Very limy soils inhibit growth, but plants can thrive in such a situation if plenty of humus is added[208]. Prefers a pH between 6 and 7[200]. Requires a rich soil that does not dry out readily[1]. Succeeds in full sun as well as in deep shade, growing well in the semi-shade of a woodland[200, 233]. In general, the sunnier the position the moister the soil should be[233]. Plants are best not grown under trees in town gardens since the soot washed from the leaves of the trees in wet weather will tend to remain on the hosta[208]. Plants flower better when grown in a sunny position but the foliage is better when the plant is in a shady position[200].
Plants are in general fully hardy in Britian, but young leaves in spring can be destroyed by frost. New leaves are only produced in the spring and very early summer, so any damage at this time has a deep effect on the plant[233].
A spreading plant with stoloniferous roots, forming medium size clumps[200, 233]. A triploid species that is not often found in the wild, it does not flower very freely and indeed there are forms that do nt flower at all[251]. The cultivar 'Normalis' flowers more freely and is very showy, but is less stoloniferous and therefore less suitable for ground cover[251].
Members of this genus are rarely if ever troubled by browsing deer or rabbits[233].
Plants are very attractive to slugs and snails, the young shoots in spring are especially at risk[111, K].
Hybridizes freely with other members of this genus[200].
