Thank you all for your input! Hubby and I are leaning towards the parthenocissus for the majority of the wall planted somewhere near the right (front) end. But I'm not sure which species would do well in my climate zone and in these conditions where the sun would be on that section for the entire day. Mine is fine with sun hitting it the entire day. If the leaves look scorched, water a bit more. Avoid P. quinquefolia (Viginia creeper) because it is too rampant. Named varieties of other species will be more tame. Expect a year or two to establish a good root system before the plant really takes off, but you should get some coverage the first year. Also, if those sticky suckers flake off, will the plant be at risk of falling off the wall? No. If some bit of the plant accidentally gets pulled off the wall, just cut that part off because it won't re-attach. A new bit will grow and stick on its own. Also, I'd still like to do one bougainvillea on the opposite corner. Anyone have tips for pruning to keep it the shape I want? Use a hedge trimmer and just shear it close to the wall. Bougies bloom on new growth, so new growth = flowers, so cutting back = more flowers, not less (within reason). Do not trim a baby plant too much. Let it establish. I'd like to have it climb up the wall at the corner and then most trail across the top section of the wall. In this situation where it will be attaching itself to the wall, how can I help direct its growth since there's nothing to tie pieces to as one would if growing on a trellis. Bougies won't attach themselves. You will have to install some strong wires or a trellis and use them to attach. Would also appreciate help on choosing a bougainvillea veiety suitable to this location/climate. I'm hoping "Orange Ice" will work because I really love the colors. A non-red color will be much less rampant and would be a good choice. Check on performance for that particular variety in your area--have you seen one growing in your neighborhood that looks good? Plant bougies in June or July when the soil is warm and do not disturb the rootball. Baby bougies are easily killed because the roots are so frail and brittle and need warmth. Established bougies are nearly impossible to kill. For planting slit the planting pot up, place the pot in the planting hole and gently pull out the pieces of the pot, leaving the roots as undisturbed as you can. Should I purchase online or would local nursery be better to ensure getting plants that are best for my area? If you have a good quality garden center nearby, that should be fine. Neither genus is particularly rare or hard to find.

By any chance, do you still have any of the evergreen wisteria seeds to trade? if so, I can send you my list. Can you tell me how long it will take before I see the first blooms? Will it take5 3 years? Thanks!

(wow i just noticed my horrendous grammar in the title. so sorry about that!) I love wisteria and will be planting 2 over a large pergola in the backyard. In fact, it will be visible from the street and should serve as something of a backdrop with the wall in the foreground. So I wanted something else on the wall :) Here's a picture of the wall coming from the other direction. The dark brown pergola looks like a shadow in this picture, but I promise it's much more apparent in real life.

And lastly, this is actually on my Healthier vine. >> I think I wasn't watering them enough when it started warming up and only really started watering them every two days about a month ago so this could be an older leaf from that. But just putting this here in case it can help>
