Re: Future trends?--clematis

I think all metal trellises get too hot for the plants. I had some black metal frames with vines on them and the leaves responed to the heat by developing an ugly thickening leaf and vine. When the season got cooler the vine was back to normal foliage. It even went over to a shrub and that foliage was normal. I know I do not like the sunshine on me in this 90 plus degree days so what can a poor plant do. No cool drink or AC for them.
Nancy Robinson Tennessee finally got some rain.
What do you think about training on metal wire loosely spiraled up a
post? I'm suspicious some clematis do not like the metal. I have
several different types of trellises -- I like old-fashioned straight
wood trellising attached to a building, or tuteurs, or arbors for the
clematis. A new vine combo I like is C.v. Venosa Violacea growing
with Ampelopsis 'Elegans' on an arbor.

===>You might have something there. Without going out and looking, it seems
that the ones on wood do seem to do better than the ones on metal. On the
other hand, the healthiest, most vigorous clematis I have is on a metal trellis
braced to an aluminum downspout. Go figure! But that is also a very moist
spot and there is also Virginia creeper going up the downspout with it, so the
shading factor may also be operating.
