What is a good colorful vining plant to cover an old ugly shed?

I like the varigated vinca. It has a purple flower and it grows very fast.

Virginia creeper is an aggressive vining plant that has bright orange flowers. It could easily cover a shed.

grape vine. a wild one- not as invasive as morning glory, and provides a good source grape jelly.

for flowers only, morning glory will do the trick.

Honeysuckle and it won't need to be replanted each year. Hummingbirds love the flowers. You will most likely have to trim it every couple years just to keep it in line or it will get bigger than your shed

I know a vine that will cover your shed. It is beautiful, has flowers and grows so fast you can almost watch it grow! Here in Oklahoma we call it Silver Lace. I have heard people call it "Hydrangea Vine". It is part of the clematis family. You do have to trim it back or it will take over. Despite that, I love it and have planted it in every yard I have had.

Kiwi Berry, Make your shed a food source! There is a male and female vine but you should have plenty of room if your'e covering a shed. Of course growing Kiwi depends where you live, but I am sure something edible in vine form grows everywhere. I don't like to have to do yard work on something that doesn't give food back!
