Sorry, Jeff, the 3 cuttings I grew this summer from Thea all went in the ground in my garden. I have one in full sun to see what it will do and two more planted at the foot of a very tall Orange Geiger.
Anna, since you are bringing plants for the zoo, I'll start an airlayer off my Thea for you. With the cold nights coming on, it will probably take a couple of months until I can pot it up, but I'm sure there will be a gathering of croton collectors in the spring.
