Hosta longissima Swamp hosta (1 Page of 5) The Hosta longissima plant species is found in E. Asia - Japan. It is a member of the Funkiaceae family. Common gardeners may know the plant as Swamp hosta. Cultivation | Propagation | General Uses Medicinal | Edible Uses Latin Name: Hosta longissima Common Name: Swamp hosta Family: Funkiaceae Author: (Honda.)Honda. Known Hazards: None known Mature Height: 0.2 Mature Width: 0.5 Habitat: Swampy grassland and other wet places, often exposed to full sun in the spring but then shaded in the summer by the long grasses it grows amongst[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]. A plant of boggy places, it is flood tolerant[187]. Does well in the semi-shade of a woodland[200] also succeeding in deeper shade[187]. 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].
The rhizome creeps extensively[200].
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].
A polymorphic species, it hybridizes freely with other members of this genus[200].
