Ipomoea quamoclit. A spectacular climbing annual, this beloved heirloom will scramble up any type of supportive structure for a profusion of little, trumpet-shaped, cardinal-red flowers with finely cut, fern-like foliage. Prior to planting, carefully nick the hard seed coat and/or soak the seeds overnight. Then, they prefer to be direct-sown after all danger of frost has passed. Or start the seeds indoors 4 to 6 weeks before planting outside. Carefully thin or transplant Cardinal Climber to a spacing of 6" to 8" apart without disturbing their roots, and plant in full sun and well-draining soil. Water moderately, as Cardinal Climber prefers dry conditions. Only fertilize lightly, as soil that is too rich will discourage flower production. Summer flowering. Height: 10' to 12'.
