Well the first flower finally opened this morning - and it's definately not a Watsonia, it's Fressia laxa alba. Lovely yes, but as I already have masses of these I was really dissapointed, I am nor closely watching two other species of Watsonia that are budding up - I have the feeling that they are also going to be Fressia (syn. Anomatheca).
Thanks Silverhill!

So sorry to hear about the confustion -- it must be maddening! have you contacted silverhill to ask for replacement seeds?
