One plant, available in HO size only.    Ocotillo cactus have thorny, long stems topped with reddish hues.   I've used cranberry color to shade tops.     Plants are approximately 7/8" to 1" in height and 3/4" to 7/8" diameter, but can be rearranged tighter if desired.    Poke wire stem into pre-drilled hole or push into foam to install.
