Okay so we moved into this house last year and I am just getting to know my garden. We had a vine growing across our pergola (trellis topped structure over a patio) that grew very quickly with tendrils and had purple berries and red leaves in the fall. I think that it was Porcelain Berry but I can't be sure because my husband killed it. We didn't like it much anyway because the berries stained the concrete, attracted too many birds and in June when it flowered, it dropped a lot of stuff which ended up in our food and drink. So, what to replace it with? For this year I may use an annual, any suggestions for full sun? For the long term, I need a perennial that will grow quickly to provide shade, preferably doesn't have berries, with or without flowers that loves full sun. TIA, I am a gardening newbie but love it!
