does anyone know hou to put 2 kind of bougainvillea together?(2color)?

Answer 1

I do not know if you can create a bicolor, but there are bicolor Bougainvillea plants available.

Coconut Ice is one. Color varies between white and lavender-pink mixed together on the same plant often on the same branch.

Try this web site for a list of bicolor types. http://members.tripod.com/~Hatch_L/boug511.html

Good Luck.

Answer 2

Are you talking about grafting, or breeding, or just planting them next to each other?
Well, no matter, call the County Extension Office in your area and talk to a Master Gardener. They should be able to help.
If not, look on the web for information bougainvilleas and nurseries selling them.
