Days to Germination:5-10 days
Ipomoea. A spectacular climbing annual, this old-fashioned favorite will scramble up any type of supportive structure for a beautiful floral display until the first frost in the fall. Prior to planting, carefully nick the hard seed coat and/or soak the seeds overnight. Then, direct-sow them where they are to grow after all danger of frost is past. Or, start the seeds indoors 4 to 6 weeks before planting outside. Carefully thin or transplant Morning Glories to a spacing of 6" to 8" apart without disturbing their roots, and plant in full sun and well-draining soil. Water moderately, as Morning Glories prefer dry conditions. Only fertilize lightly, as soil that is too rich will discourage flower production. Morning Glories require a trellis, fence, string, lamppost or mailbox post to support their long, climbing vines and profuse flowers. Summer flowering. Height: 6' to 12'.
Days of Vines and Roses
If you’re looking for a great trellis on which to grow an annual vine, consider a sturdy, well-established climbing rose. The thorny canes provide excellent support, and won’t mind a little competition. Since the vines will come into their glory later in the season, they’ll add color to a rose that has finished its main flush of bloom. But any overlap will produce handsome combinations as well: Hyacinth Bean or Sweet Peas with a pale pink New Dawn rose, or blue Morning Glories with your favorite yellow-flowered climber.
