I have both red and green, in the ground. The red is actually kinda dark maroon color. Palm Springs is pretty similar to my area (Bakersfield), mine are in partial shade. The green seem to like heat/sun MUCH more than the red.

I got the red ones, four of it. I am going to plant them in the ground under a patio canopy, so quite shady. Let's how it goes.

Are yours matured? How big do they get?

I got one of these early in the summer and every time the sun hits it, it burns. After putting it where it only gets the first and last hour of actual direct sun, it's stopped burning and making much more colorful leaves.

toffee-el:

I think my green and red Ti plants are mature, but they will never reach their full genetic potential, simply because they're not in an ideal environment like Hawaii. In the photos below, you'll see that mine are much shorter (about 3'), compared to those Ti grown in Hawaii (at least 6', and some above 10').

Well that's amazing. Those don't look burned at all, obviously not in the shade. I don't get it.

This is my experience--- the more tropical and red you want them to look, the more shade I had mine with 2 hours of sun and they got dull and green with very little color, then I put them in the shade and im already seeing color improvement in the leaves, it says "bright light" I recommend shade, dappled shade, or 2 hour of sun max, the leaves do get scorched
