Yes, I did indeed research this plant's gripping method with regard to
potential structure damage. Every data I have seen has proclaimed the
vine's "non-damaging" nature. If anyone has evidence otherwise, I
would be most interested.

I've seen a 30-year-old Hydrangea anamolis petiolaris up close,
climbing up the side of an old brick house. I could detect no damage
to the structure (at least, no more so than the rest of the 50+-year
brick and mortar looked). The homeowner (my aunt) has not experienced
any problems from the vine -- it's a striking and very distinctive
part of her home.

My main concern is whether to plant it so that it gets some P.M. sun,
or no direct sun. However, I do thank the other posters for their
well-intentioned warnings.

I have to take up a contrary position to the other posters on this subject.
Hydrangea anamolis petiolaris will not damage those surfaces to which it
clings. It does need support as it will become quite woody and 'deep', but
it won't damage via its gripping mechanism, which is either vegetative
'hooks' or by excreting pure calcium carbonate which cements the stem to the
structure. A great choice for the sites you mentioned!

Hello,

After much search, I am ready to plant a very nice, large 3-ft tall
climbing
hydrangea (Hydrangea anomala petiolaris). I have one of two sites in
mind,
though.

One is in fairly deep shade, and the vine can climb over and around the
railings of the north-facing front porch.

The other potential site is on the western edge of this same porch, where
the vine can climb up the railing corner and possibly up the side of the
house. It will receive more sun in this area -- qualifying it as a
"partial
sun" location (afternoon sun, but shaded in part by the house next door).

I think it would look great if this vine would grow up the side/corner of
the house. However, my house has vinyl siding. Although the web sites
I've read say "Its climbing stems cling to whatever it is growing on" --
I'm wondering if this means siding, too? Or is the siding too slippery
and
impenetrable for the stems?

Any advice much appreciated.
