Manfreda -- sources and reference collections

Dear Luc,
Surprised no one has mentioned Yucca Do Nursery in SE Texas.
http://www.yuccado.com/

They have 2 or 3 Polianthes and Manfreda in their current
listing, but I suspect they may offer others (too few to list) if
you ask.

They are a very reliable and exciting nursery and a excellent source.

The only help on the Prochnyanthes is seed from the
rarepalmseeds.com site as Agave bulliana

Good luck. Jim W.
