Heronswood Nursery in the 2006 catalogue, lists three vines that grow
in shade and can grow into trees:

1. Schizophragma hydrangeoides "Moonlight"

2. Schizophragma hydrangeoides "Roseun"

3 Hydrangea anomala ssp. petiolaris

These descriptions are not the same as the new catalogue! Does anybody
have any experience with these? So, if they grow into trees, how does
that effect the tree if at all?

They also list Aralia cordata as a zone 6 plant!

Wonder if they push the zones plants can be grown in?

And Pseudopanax ferox:

Looks like it may be an interesting conversational plant to go inside!
Anyone have any further information on it?
