Let's see your jumbo propagations!
The trunk on the left (Dracaena marginata 'Tricolor') was added to this pot as a cutting this past fall (with regular D. marginata that has a little air plant in the crook of its' trunk, a Begonia.)
I just added the piece of Ti plant (Cordyline fruticosa) in this pot a couple hours ago (with existing D. marginata 'Tricolor' trees.) Pretty sure I got the stem all the way to the bottom of the pot. Hope it makes roots all along that length, like the Dracs do, so I can raise it a little whenever I repot, for an interesting exposed-roots look that I like, although I had to put the rock there to stop squirrels from constantly digging in this pot.
