Culture

• Prefers a sunny position in a light well-drained dry to moist soil [1].
• Bulbs are not hardy in all parts of Britain, they probably tolerate temperatures down to between -5 and -10°c but because of their need for a very well-drained dry to moist soil are probably best grown in a bulb frame [90].
• The plants need a dry period in late summer when they are dormant in order to fully ripen the bulb [203].
• Les bulbes doivent être plantés assez profondément [1].
• Most members of this genus are intolerant of competition from other growing plants [203].
• Pousse bien avec la plupart des plantes, notamment les roses, carrottes, betteraves et camomille, mais inhibe la croissance des légumes [18, 20, 54].
• La plante est un mauvais compagnon pour la luzerne, chaque espèce affectant l'autre négativement [201].
• This species is a cultivated crop in Iran[105], where it is sold in the bazaars of Teheran [183].
• Les membres de ce genre sont rarement (ou jamais) incommodés par le broutage des cerfs. [233].

Propagation

• Graine - Semez au printemps sous un chassis .
• Prick out the seedlings into individual pots when they are large enough to handle - if you want to produce clumps more quickly then put three plants in each pot .
• Cultivez les sous serre durant au moins leur premier hiver et plantez les à leur position définitive au printemps, une fois qu'elles poussent vigoureusement et sont suffisamment développées .
• Division au printemps .
• The plants divide successfully at any time in the growing season, pot up the divisions in a cold frame or greenhouse until they are growing well and then plant them out into their permanent positions .
