Following up to Rodger Whitlock

Also, is your allotment sunny and dry enough? I consider C.
sativus a somewhat demanding crocus species, requiring warmth,
sun, and quite dry soil in summer. I suspect it also does best in
fairly rich soil, so may need regular (i.e. annual)
fertilization.

Its very sunny and very dry. Next to a river, the soil being
originally silt underlaid with gravel a few feet down. The cold
winter requirement mentioned elsewhere might be a problem.
