Perenial trellis plant

Hello

I am looking for a perenial that will trellis up latis. I live in a mobile home in California and am looking to shade my home during the summer months.

Trumpet vine is really very pretty, honey suckle or Virginia creeper.  Grapes might work especially the native varieties.

If you post a location you might get ideas especially for that location.

Zone 9b. Morgan hill California. Might put one in a half wine barrel. I need to cover about 25 feet long and 12 feet of height.

I don't live that far from you, and ones that have worked well for me are potato vine (not really a potato, but that's its common name) and passionflower. The passionflower will cover quickly, and provides habitat for the gulf fritillary butterfly.

If you're up to building a very sturdy trellis, you might try some variety of kiwi. You'd need a minimum of vines (male and female) for fruit, but if all you need is shade then a single plant would work.

Again, for fruit, make sure you compare chilling hours. Like many fruit trees, some varieties won't set fruit until the get a sufficient amount of cold weather. I get the impression that hardy kiwis (which give grape sized kiwis you eat whole, skin and all) are less fussy. It's the species commonly found in our nurseries here in zone 8b.

Homeguides.sfgates.com has a few good recommendations for your area on this page and links to several others that may be of interest. I liked their idea of pot grown cucumbers on a trellis.
