Hi Maggi,
Thanks! I have 3 clones and none are pure. I don't know what other Australians have but I doubt if there are any different ones here although one could have arisen in hort, but I doubt it.
Anyway the upshot is I don't think there is anything wrong with Chris' plants, just a splash of aberrant colour!
Cheers, Marcus
PS Very pretty crocus in Sandy's article.
