Leptodermis oblonga dwarf lilac
I have had 2 False Lilac since 2005 that I got from Park's and they are zone 5. I am zone 3 or 4 but thought I could make it work by covering in the winter. First year they bloomed in their pots. Brought them in for the winter and kept in a cool place, 40 degrees. They bloomed very little that next summer. Have been leaving them outside in the ground these last years and they come up but never get to bloom. Last winter was really cold and I covered them well but they are just coming up nicely now. They are only a few inches tall. I thought they wouldn't even come up. Our first frost could be anytime now, or hold off for a few weeks. If I would dig them up this fall and bring them in the house,giving them a lot or light, maybe they would bloom? Do they bloom on new wood? Or, should I dig them up and keep them in a cool/darker place again like I did the first year or so? They really didn't seem to thrive that way either. Any advice would be appreciated.
