Answer: Our plumeria blooms!!
I received this plumeria three years ago from someone at work. The first year we had it, it bloomed. Just three small flowers - and that was it. Since that time, it's grown like crazy, but it hasn't bloomed. Last weekend when I was out watering, I spied buds!! I was so excited I came running in to tell Kevin!! This past Thursday, when I was leaving for work in the morning, I saw that the first bud had just started to open up; by the time I came home, it was in full bloom. Shortly there after all of the buds started opening. Today it's in riotous bloom. YAY!!
...I guess sometimes it pays to just leave something to it's own devices =)
