Vines

If you're running out of garden space, consider growing vines vertically on trellises, arbors, or fences.  A good annual to try is morning glory.  I start seeds outside in late May. Morning glories don't like to be transplanted so decide exactly where you want them. They bloom from midsummer until frost in shades of blue or pink.

Perennial vines include clematis and wisteria. There are many varieties of clematis in lots of colors. Some are spring bloomers, while others flower in summer or even fall. Check the tag when you buy one to see when to expect flowers. They also have attractive seed pods.
Wisteria vines are very woody and need strong support. After planting they may not bloom for several years. They need full sun to thrive. The blue or light purple panicles flower in April.
