It is funny how we all have different times that our trees go dormant or semi-dormant. All fall I waited for leaf yellowing/dropping and finally thought that mine would just keep their leaves. I am just referring to the six trees in the S room. December/January began their dormancy and some lost all leaves and some most leaves. Now some of trees are beginning to leaf-out. The dormancy cycle certainly wasn't due to temperature, since the S room never got below 62F. The trees get several hours of sunlight but that sunlight is filtered by the roof-glass. I guess the suns intensity/time of exposure triggers the dormancy.
Lucky, I try to keep all my plumeria within 7' height. They are "trees" in nature, so the height probably doesn't matter. I do have 2-3 compact/dwarf varieties and it doesn't look like they will get over 4' tall (so far, anyway). I guess they are still trees, just dwarf ones.
