Ray and Anne,
Difficult to answer such a question. It's true that in Europe also, Japanese species emerge very early, before the Himalayan. It depends so much on the way they are grown. Nurserymen in Holland, know that very well and can get flowers of anything almost at any time.
Now, what do our Australian friends think of that?
