Physical Characteristics

Perennial growing to 0.6m by 1m . It is hardy to zone 5 and is frost tender. It is in flower from May to July, and the seeds ripen from August to September. The flowers are hermaphrodite (have both male and female organs) and are pollinated by Apomictic (reproduce by seeds formed without sexual fusion). The plant is self-fertile. We rate it 2/5 for edibility and 1/5 for medicinal use.

The plant prefers light (sandy), medium (loamy) and heavy (clay) soils and can grow in heavy clay soil. The plant prefers acid, neutral and basic (alkaline) soils. It can grow in full shade (deep woodland) semi-shade (light woodland) or no shade. It requires moist soil.

Habitats and Possible Locations

Woodland, Sunny Edge, Dappled Shade, Shady Edge, Deep Shade, Ground Cover.

Edible Uses

Leaves Stem.

Young leaves and leaf stems - cooked. The white part of the stem is boiled[46, 61, 177].

Medicinal Uses

Disclaimer

Odontalgic.

Odontalgic[74]. The root is used.

Other Uses

Ground cover.

A good ground cover plant[104], succeeding in dense shade but rather slow to spread[197]. Plants should be spaced about 60cm apart each way[208].

Cultivation details

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 Britain, 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 vigorous plant, forming medium to large clumps[200].
Hybridizes freely with other members of this genus[200]. Since this species produces its seed apomictically, it should breed true[200] (unless there is also cross pollination of course).
Cultivated for its root (used medicinally) in China[74].
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 number of named forms have been selected for their ornamental value[187].

Propagation

Seed - sow spring in a lightly shaded position in a greenhouse and only just cover the seed. Germination usually takes place within 1 - 3 months at 10° c. Make sure you keep the compost moist. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts.
Division is possible at almost any time of the year so long as there is sufficient moisture[233]. It is best carried out in March as growth commences or in early autumn if the soil is not too dry[200]. Hostas can be left undivided for many years and should not be divided any more frequently than once every 3 - 5 years to allow the leaves to reach maturity[200].

Cultivars

'': There are some named forms for this species, but these have been developed for their ornamental value and not for their other uses. Unless you particularly require the special characteristics of any of these cultivars, we would generally recommend that you grow the natural species for its useful properties. We have, therefore, not listed the cultivars in this database[K].
