Need input on sweet pea vines - are they invasive or hard to care for?

I set up this area in 2012 - 2 roses & 3 rose of sharron - I have 6 sweet pea plants, that I am thinking of as a back drop - does anyone anticipate a problem with using them in this way?

    I have found that the invasiveness of things like Sweet pea have to do with where you live, and how much attention they get. I have a hard time getting them to actually grown here in Southern Oregon, we have cold winters (below freezing usually not more than 5 or 10 degrees) but very very hot summers with many days usually over 100 and not humid at all. Also if you are planting from seed usually they are annuals, there is a perrenial variety that can be very invasive but usually in long forgotten fiends etc. Some information http://indianapublicmedia.org/focusonflowers/invasive-sweet-pea/

    Here's one consideration. I suspect that annual sweet peas bloom in late summer where you are. This is the same time rose of sharon blooms, so when your rose of sharons get larger, which it certainly will, they will basically block the view of your sweet peas.

      @Carol S I think that's sort of tricky to do with rose of sharon, but you could try.

    I moved into my house 12 years ago.....I have been trying to rid myself of sweet pea ever since. I just pulled a number of plants out just the other day when I was thining out some plants. They will cover your fence and make it look beautiful, they they will spead and spead and spread!

      @Carol S I have been pulling them for so long, that by the end of summer I usually have none left that I can see, so I'm not really sure if they die back or leave woody vines....but they come up fresh every spring.

    Are you in zone 6? if so those rose of Sharon may get large. What color are they? I know here in zone 7 the white with red centers are very prolific reseeders. I have a double ruffle purple one that is now about 12' tall I think! Enjoy them and watch for the hummingbirds, bees, and butterflies. Happy gardening!

    Wow wish I could get sweet pea to grow, I have tried everything and can't get them started. Mom had them on a chain link fence when I was little and they smelled so good, she used to pick a bouquet of them every day for the house..

    Everytime I view your input photo, this thought crosses my mind; the three are close enough that they will appear as one 8 to 12 foot wide mass. If you wish them as stand alone trees you might want to separate them while young and manageable.
