Plant in sheltered, sunny borders, just covering the top of the bulb with good soil or grow in large pots - leaving the top of the bulb above the soil. This variety is quite hardy and will overwinter outdoors in Southern half of UK. Choose a sunny sheltered position, preferably at the foot of a south wall and where the soil is light, rich and well drained. Plant before the end of April, about 15cm (6") apart, with the bulb just below the soil surface. Protect during the winter with a good layer of leafmould, garden compost or bark chippings, remove in spring. For cold greenhouse culture, set one bulb to a 10cm (4") pot or three to a 15cm (6") pot. Plant in compost, avoiding rich conditions with the top 1cm (½") of the bulb protruding. Rest pot grown bulbs after flowering. Only re-pot every 3-4 years.
