I have only had Heavenly Curls for 2 years and so far it has been pretty slow in establishing itself, as with most Gossards I have purchased. The first year I only had about 4 flowers on it. This past summer was a bit better so I am anticipating that this plant takes a few years to settle in. Sometimes the third year is a charm. I am anxious to see how it does this summer. So far it has now reached its registered stats. Hopefully once it settles in it does.
