This past year, I bought four singles (the only way they were offered for sale), and they
doubled. Just stepped outside to count them.
Three of the singles bloomed and I used the pollen. Small plants with normal sized bloom.
Amazed me to no end. Now, if they will just make it through the winter. The one that did
not bloom was a bonus plant, so can't complain.
Also bought two plants (double fans each) that have not increased at all, although they did
bloom and again I used the pollen.
