Thank you Dodge, a lot, for your help!
Margaret, I have had it since the Sunday School kids planted a tiny little piece in a styrofoam cup, which they presented to each woman after church last Mother's Day. I repotted it and it has gotten bushy and 8" tall, probably 10" across at its fullest part. Was loaded with about 20 buds which bloomed 3 or four at a time, but this last crop of that many buds got fat but wouldn't open, finally fell off. I have fallen in love with the plant
. Right now it has no buds and I assume it is going into a dormant stage (maybe why the buds wouldn't open.) Thanks for your interest.
