Scientist Says These Trees In Latin America “Walk” More Than 65 Feet A Year

7. We have kalanchoe that do the same trick.

No stilt-roots, but they grow tall and unstable, to a height of 3 feet or so, perhaps more. Then something knocks them over. Where they touch something with enough moisture, they put down roots and grow. After a couple of fairly mild winters (even with the vortices last year, those near our back porch managed to survive) some have migrated their growth points 6 or more feet. Hard to be sure, their original roots are long gone.

I guess they're now Bryophyllum daigremontianum.

There's at least one species of bent grass that grows around Houston that does the same trick. It grows up, flops over, sprouts roots from a joint in the stem and continues to grow.

I guess it's odd in a palm.
