Hydrangea petiolaris (climbing hydrangea) is a nice idea for shade - though you need to make sure the fence is a sturdy enough support.

Morning glory shouldn't qualify as invasive (are you thinking of reseeding?), especially in that setting.

You can find more ideas here.

I grow several clematis in partial/mostly shade - on the E. and W. sides of a garage that sits under two huge willow trees - and I'm quite satisfied with the amount of bloom I get. You can always put them in large pots to start with so they'd be easy to move if they don't do well. Mine are actually all in pots, as the willow doesn't leave much in the soil for other plants to thrive.

Climbing Hydrangeaa is a lovely plant. Eric is dead on, though. Most people see "partial shade" and fork over the money... failing to realize that this plant attains HUGE proportions and ought to be sited with as much care as one might use when siting a tree. No kidding!

They are also notoriously slow in flowering. Think about it, they get really big. They spend the first few years setting roots. All you see are some leaves and a little bit of top growth. Uninspiring, at best. But then they start to grow and flower. They're gorgeous.

But they keep on growing! and too many people quickly realize the trellis is inadequate, they don't want it stuck to the side of their home or chimney... .

Great plant, I wouldn't surrender our's, but site it carefully and be prepared to wait for results. It won't disappoint.

I, too, do well with Clematis in partially shaded locations. I've been disappointed in Honeysuckle... will yank it and replace it with another Clematis, probably.

I also love Aristolchia durior (Dutchman's Pipe), but it's grown for the magnificent leaves, not the little weird flowers that lend the plant its name.

Thank you all for your insights and suggestions.

eric: where we lived previously the morning glory got into everything (not on our properity) but you are right, I didn't factor in that we are now in a different zone. Thanks for the link.

karinl: could you tell me what kind of clematis you are growing?

chelone: can you tell me why you are disappointed in the honeysuckle? I had never seen Dutchman's pipe - the foliage is beautiful. Do the vines die back?

I've never gotten the kind of flowers from Honeysuckle that I've gotten from Clematis. It's been OK, but compared to "Polish Spirit"... pretty anemic performance. But that's just MY experience, your's might be very different.

Aristolochia durior loses the leaves when the temperatures drop. The vines remain and resprout in the spring. This is also a very large, very vigorous vine. Think of it in the same category as Wisteria, Climbing Hydrangea, Trumpet vine. They will overwhelm a $20 trellis in a year's time.

Have you checked out the Vine forum? it's a lot of fun, with many, many devotees of "gardening in the third dimension". You will glean much from them!
