Re: holdfasts...was: Hydrangea...vines growing thru shrubs/trees -Reply

Penny's right.

'Smatter of fact, sent a private message regarding holdfasts last
night.  Here, FWIW is part of it with links to images of both kinds.

-----
There are two kinds of hold fasts, more or less.  Ivy and climbing
hydrangeas (including Schizophragma who is a close hydrangea
relative) have one kind that looks like little roots, but they aren't
roots in the sense that they can derive nourishment from their host.
The Parthenocissus bunch - including Boston Ivy (which is not an ivy)
and Virginia creeper have another that is like a little disk.

If you'd like to see the difference, I scanned both for my series on
vines a few months ago.
http://www.suite101.com/article.cfm/shade_gardening/24583 - scroll
down - they're at the end of the article; have both types here, with
a real close-up of the Virginia creeper disk, which is rather
incredible.

Penny...can take quite a few years to bloom - at least mine did - but
don't give up on it as it will eventually do so.

Hi Kathy - the Hydrangea has little holdfasts.  I have one which
climbs against a walled in deck  It is now 4 years old and really
started to take off last summer.  No blooms yet and not sure how long
it takes before  they bloom.  It receives only part sun - mid to late
afternoon.  I like its deep green leaves, even without the blooms.
