Under condition much poorer than David's, my seedlings of titanum
entered dormancy about 2 years after germination, with tubers about 2
inches, 5 cm. Dormancy under my home conditions lasts 2 - 6 months,
though I try to time dormancy breaking to very early Spring in order
to take advantage of the height-shortening effects of the Summer sun.
Each cycle has resulted in a 6 - 10 fold increase in the mass of the
tuber. As a house plant, I have found it big but adaptable.
