I've had this on the Plant ID forum, but thought I'd put it here as well. Bought this spring at Wal-Mart without any label at all. Now it's blooming, but without any pups so it may be committing suicide. First photo was taken in June; 2nd photo in October; the closeup today - plant is still growing at 5'10". I want to label it 'Kalanchoe luciae' based on the bloom. What do you think?
Edited to add these photos taken today. It finally topped out at about 6'2". I think it has passed peak bloom now and still no sign of any pups. The lower leaves are drying up and falling off now, but that may be the result of changing habitat from outside to inside the closed porch. It's really hard to maneuver at that height and it's really unstable. The pot isn't large enough or heavy enough to counter balance the growth.
