There are several flowering stems on each branch, but flowers are borne only on one side of the stem. The flowers have a long vase life lasting several days and prove to be a delight to hummingbirds. Sure we miss-timed the tunnel or the Creator gently reminded a bunch of scientists He is ultimately in control. Considering this vine produces these flowers in one season from seed makes me wonder why it is not more widespread. With arbors, trellises and towers becoming the rage, this is a great plant to select.
Plant seeds into well-drained, fertile soil after the soil has warmed.
Soaking the seeds overnight helps the germination process that takes place in 10 to 16 days. Space plants 18 inches apart. This is a vine that needs plenty of sun and a sturdy structure on which to climb. The vines are capable of growing 10 to 20 feet and will be there a long time. Mulch after planting.
