I think you might be right! The leaves are slightly tinted red around the edges, so I guess we'll see how it progresses as its exposure continues!

Kalanchoe thyrsiflora and Kalanchoe luciae are very similar and often one is mistaken for another even by the grower - I believe that K. luciae is more common; it has more color to the leaves and pale yellow flowers. K. thyrsiflora's leaves are more chalky green or white waxy leaves and scented flowers that are more brilliant yellow. Mother plant dies after flowering, but usually there are few new pups to replace it...Rina

Do you think this guy is fully grown? Meaning, do you think he'll change at all in the time that I have him?

...we posted at the same time - they grow tall, and bloom when mature...color of leaves of K. luciae will change a lot depending on light and temperature.

Thanks so much for your input!
