Cultivation Details:
Prefers a rich moist but well-drained soil[1, 42]. Shade tolerant[31], it is easily grown in a cool leafy soil[90] and grows well in light moist woodland[203].
Plants are not very hardy outside the milder areas of Britain, they tolerate temperatures down to between -5 and -10°c.
The bulbs should be planted fairly deeply[1].
The seeds have an oil-bearing appendage which is attractive to ants. The ants carry the seed away to eat the oil and then discard the seed, thus aiding dispersal of the plant[203].
Grows well with most plants, especially roses, carrots, beet and chamomile, but it inhibits the growth of legumes[18, 20, 54]. This plant is a bad companion for alfalfa, each species negatively affecting the other[201].
The flowers are sweetly scented[245]. The picked flowers can remain fresh for several weeks[89].
Members of this genus are rarely if ever troubled by browsing deer[233].

Propagation Notes:
Seed - best sown as soon as it is ripe in a greenhouse or cold frame. It germinates quickly and can be grown on in the greenhouse for the first year, planting out the dormant bulbs in the late summer of the following year if they have developed sufficiently, otherwise grow on in pots for a further year. Stored seed can be sown in spring in a greenhouse.
Division in summer after the plants have died down.
