Opuntia ellisiana
Thornless Prickly Pear Cactus
There is some confusion over the origin
and hardiness of this plant. Luther Burbank
started breeding Opuntia around 1900 to
achieve a spineless form that was palatable
as cattle feed. One of his crosses resulted
in a spineless form that was named 'Bur-
bank’s Spineless' and is still growing in his
California garden today. We are not sure if
we have that variety or one of his selec-
tions of the Texas native O. ellisiana. Based
on our plant’s hardiness, we probably
