I have had Heartbeat of Heaven for 5 years and love it!!!! It doesn't increase very fast but blooms for a long time. I have never actually counted buds but I would bet it has over 20 per scape. Scapes grow to their 32" height here. The first 2 years I had it, I could not set any pods and even the pollen didn't work. Once it settled in I have set many pods on it. Last summer it did rebloom for me. The flowers never fade here and have great substance. Can't say enough positive about this plant!!!!
