Tarev/Simon, for my plumeria at least, some are regular bloomers, some irregular, and some are really "constipated". I am sure Hetty would know why that is. I only have my 18 or so varieties to go by. I have had only 3 varieties to bloom so far (my season was delayed a month!) and several plants of those three varieties are in bloom. My Malaysian Red is in bud, so it will be my fourth one.
