I was on some allotments at the weekend and was struck how bare and scruffy they look at this time of year. We've passed the Spring equinox, but seedlings…
Grow in a fertile, well-drained soil, in a position which gets full sun. The bulbs should be planted in the autumn and will prefer to be grown in hot dry areas in a sandy loam-based potting compost.
You can grow from seed or divide the clumps in spring.
