Hello everybody! I have cultivated Opuntia species for many years, but never really paid good atention to them. Now, several of my plants are in bloom and i have gotten interrested in this genus and about artificial pollination of Opuntia.

I have tried to make a research about pollination and about this genus, but have not found good info about it.

So i have several questions:

I was wondering if it is possible to cross pollinate different species?

Are Opuntia species self-fertile?

Are there any sub-groups or tribes inside Opuntia genus that cannot be cross pollinated one with the others?

Do you know any good site that can provide good info about Opuntia?

Any help given will be much appreciated;0)

Thank you,

Jorge Joel...
