Hosta ventricosa () is a Perennial which grows to a height of 0.6m and a width of 1m . It has a hardness rating of 5and is quite resiliant to frost.
Hosta ventricosa will flower in November to January. the seeds ripen from February to March
The flowers from this plant are hermaphrodite (has both male and female organs) and they are pollinated by Apomictic

Soil Information

Hosta ventricosa will grow in light (sandy),medium (loamy),hard (clay) soil. It is not necessary for the soil to be well drained.
The soil prefers the following PH / acid levels :
- pH of less than 6, Acidic soils
- pH between 6 and 8, Neutral soils
- pH greater than 8, Basic soils
Hosta ventricosa prefers moist soils

Ideal Planting Locations

Hosta ventricosa can grow in full, semi shaded areas and areas with no shade.

Rocky or stony river banks near ponds and lakes[74].

Planting places suited to this plant described below.

• Grows within a woodland garden
• Grows on a sunny edge
• Works within dappled Shade
• Grows in a shady edge
• Is suited to a deeply shaded location
• Can spread to cover ground and will out compete weeds

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].

Edible Uses*

* See disclaimer
Edible Rating: 2/5
Young leaves and leaf stems - cooked. The white part of the stem is boiled[46, 61, 177].

• Leaves -
• Stem - this often intergrades into leaves.

Medicinal Uses*

Medicinal Rating: 1/5
Odontalgic[74]. The root is used.

• Odontalgic - Treats toothache (temporary measure only) and other problems of the teeth and gums.

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].

Known Hazards

None known

Other Uses

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].

• Ground cover - Usually low growing plants that can be grown with other plants, especially shrubs and trees, to prevent the growth of weeds.

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].
