I really love the Ti plants too; I make leis, so they come in handy and I am trying to get a selection going in my yard. I'd love a piece of that Keely's Golden and Princess Lesha!!! Let me know if you're willing to trade any time.
I find they root very easily from a 6" stick in a glass of water; I then transfer into a pot with soil and once well established they go straight into the ground.
