First, it's not a 'tree' ha, ha; that's a misnomer--something I think the marketing people dreamt up as a gimmick. I was dissapointed in it when I first got it. The flowers are not as dark as those marketing pictures show by any means. I'd say it's more of a deep, dark, dark pink rather than dark purple as I expected. Otherwise mine are nice strong growing and hardy lilies. Mine are about 48 to 60 inches tall affter being in the ground here four--going on five years now. I've grown to kinda like it over time. Overall, nice plant characturistics.
