I'd go with the morning glories both blue and white and I'd plant 1 of each in each pot. Morning glories have large leaves and 2 would fill in the spaces. They are also fast growing but their maximum height may be a tiny bit less than 10 feet. Nasturtium and thunbergina won't give you the coverage you want. Their maximum height is much shorter than 10 feet

Hi hope037, my DH built a large pergola over a portion of our back deck. I don't grow anything over it but I do grow clematis up the posts. I thought about growing something over the top but several things stopped me: leaf litter, loss of light to the inside and painting/maintenance. We like to dine under this area and decided we'd rather not deal with the debris that might fall all over the deck if we could avoid it. Also, the pergola cuts down on the light entering the kitchen, which is fine because we have loads of natural light coming in through other windows, but we thought a dense vine would shade more than we'd like. Finally, painting/maintenance could become a chore if whatever we grew had to be chopped back to do so. You may want to consider them, too. Just thought of something else. If the vine attracts stinging/biting insects you or your guests may be running for cover somewhere else. ; ) Please don't get me wrong - I love covered pergolas. Just trying to help you explore the pros and cons of a vine covered one over a patio. Diana

I've been growing it here for years, others have grown it up here also - I once saw one at the Froggwell garden of the late Holly Turner back when she was still there and able to come out and receive visitors. She had it trained onto a shed. There are no significant problems other than it having enough vigor to perhaps catch some people off guard. Not as large-growing as many relations, however, including R. brunonii. A hard winter such as the one in 1990, when it got below 10F would probably kill it to the ground, as it did with R. brunonii and many other kinds of roses both musk and non-musk.

I would plant in the ground as it's just easier, and there are a number of vines that will get tall enough to climb to the top of and over your pergola. Managing plants in pots is more challenging than planting in the ground. Regardless of what you plant, you will want to provide wires or wire mesh or pegs for the vines to climb up your verticals since most vines twine and can't grip something as large as your posts, and this would apply to all the vines I am suggesting. Check out the native trumpet honeysuckle, Lonicera sempervirens, particularly the cultivar 'Major Wheeler'. It would be at least semi-evergreen in your area, and in my garden has a massive flush of bloom in late May-June, but then it continues to flower throughout the summer on any new growth right up until hard freeze. Unfortunately, no scent, but the hummingbirds love it. Regardless of what you plant, you will want to provide wires or wire mesh or pegs for the vines to climb up your verticals since most vines twine and can't grip something as large as your posts. Wisteria is stunning when it is blooming and the Asian types are nicely scented, but requires vigilant pruning and can send up vigorous suckers and seed-grown plants quite a distance from the mother plant. Many folks find it difficult to control. It blooms for just a few weeks in spring. I am partial to Clematis, though they mostly aren't scented. You would need to choose varieties that grow to several meters such as Betty Corning or many of the other viticella hybrids. Pruning is easy for the viticella hybrids - just chop them off to a couple of sets of buds per stem in early spring before they leaf out, and they will have grown tall again within just a few weeks.
