Melanthium virginicum
Family: Melanthiaceae
What it is like
Melanthium virginicum is a PERENNIAL growing to 1.7 m (5ft 7in). See above for USDA hardiness. It is hardy to UK zone 5. It is in flower from July to August. The species is hermaphrodite (has both male and female organs) and is pollinated by Insects. Suitable for: light (sandy), medium (loamy) and heavy (clay) soils. Suitable pH: mildly acid, neutral and basic (mildly alkaline) soils and can grow in very acid soils. It can grow in semi-shade (light woodland) or no shade. It prefers moist or wet soil.
Height (m): 1.7
Where it is found
Lowland prairies and moist open woods. Bogs, marshes, wet woods, savannas, meadows, along railroads at elevations of 10 - 800 metres.

How it is grown
Requires a deep fertile moisture retentive humus-rich soil. Succeeds in full sun if the soil does not dry out but prefers a position in semi-shade. Dislikes dry soils. Grows best in a cool woodland garden or a north facing border. Succeeds in acid soils in a bog garden.
Propagating it: Unless the seed is stored in damp sand at around 4°c it has a short viability. Where possible it is best to sow the seed in a lightly shaded position in a cold frame as soon as it is ripe. Stored seed needs to be cold stratified but can be very slow to germinate. Germination can be erratic even for seed sown when it was fresh, it usually takes place within 3 - 12 months at 15°c but can be much longer. Sow the seed thinly so that it can be grown on in the pot without disturbance for the first couple of years. Give an occasional liquid feed in the growing season to ensure the plants do not become nutrient deficient. The plant produces just one seed leaf in its first year, this forms an over-wintering bulb. At the end of the second year's growth, pot up the over-wintering bulbs, placing one or two bulbs in each pot. Grow them on in a lightly shaded position in a cold frame for at least another couple of years before planting them out into their permanent positions. It takes up to 10 years for the plant to reach maturity. Division in March/April or in October. Establish the plants in pots in a shaded frame before planting them out. Root cuttings, 6mm long with a bud, rooted in a sandy soil in a cold frame.
