Thirty years ago I bought seed from T&M~~ Champagne
perpetual~IMMSMC! I grew a row of thirty crowns which varied tremendously
but were ideal for my needs. They have now all been discarded {a fresh
garden has been made} but in all those thirty years not one ever produced a
flower. I have no explanation. With unlimited fym and seaweed, overfeeding
is a possible explanation but highly unlikely.
Non flowering cannot have been part of their heritage!! So
what~~~~~~???
