Please recommend annual vines with bright flowers. I want to grow them in full sun on a tall trellis (they can grow 10 to 20 feet).
There are several annual vines which will grow in full sun and give you plenty of color most of the summer. Here are a few:
- Morning glory, which comes in blue, white, pink, and red, is a fast-growing vine that blooms from July until frost. It is easy to grow, even in poor soil conditions.
- Hyacinth bean can reach up to 15 feet in one season and has beautiful lavender flowers and purple bean pods. The foliage is an attractive dark purple/green.
- Cardinal vine has bright red flowers and grows quickly up a trellis. You can easily start this Ipomoea from seed.
