Crinum
The bulbs grow well in full sun or light shade and prefer rich soil with plenty of moisture. In mildly cold areas such as Holland they are best protected over winter with a mulch of dry leaves or bark. Further north (Central Germany, Scandinavia), gardeners are advised to grow the bulbs in pots that can be moved inside over winter. Plant garden bulbs about 5cm deep; plant potted bulbs with their neck barely covered.
Any mild fertilizer can be used at intervals throughout the growing season. Bulbs should be left undisturbed and may not flower for one or two seasons after being lifted and moved. Let the soil of bulbs grown in pots become slightly dry while plants are dormant in winter. Height 60-80cm.
