Purple Bell Vine is a stunning climbing flower that brings deep, rich color to summer and fall gardens from June through November. This heirloom variety grows 6 to 10 feet tall on a slender, graceful frame, making it perfect for trellises and vertical spaces in zones 8 and warmer. From seed to first bloom takes about 112 days, so starting indoors 8 to 10 weeks before your last frost sets you up for continuous flowering through the cooler months.

Purple Bell Vine earned its name from the distinctive bell-shaped flowers in deep, dark purple hues that dangle along the vines like tiny lanterns. The extended bloom season from early summer all the way into late fall gives you months of color when many other vines are fading. Grow it as a tender annual in cooler zones or a perennial in zone 8, training it up a sturdy trellis to fully showcase its elegant, climbing habit and delicate flowers that magnetize hummingbirds and bees.
Purple Bell Vine is grown primarily as an ornamental flowering climber. Train it up trellises, arbors, or garden structures to create living walls of summer and fall color. It works beautifully in containers on patios and balconies where you can position a small support structure to guide its upward growth.

Sow seeds indoors 8 to 10 weeks before your last frost date in pots kept at 70 to 80 degrees Fahrenheit. Seeds need light to germinate, so sow them on the surface or press very lightly into soil. Expect sprouts in 14 to 40 days. Harden off seedlings by gradually exposing them to outdoor conditions over 7 to 10 days before transplanting.
Transplant seedlings outdoors after the last frost date when soil has warmed. Space plants 9 inches apart in full sun. Dig holes large enough for the root ball and gently firm soil around the base.
Direct sow seeds into warm soil after the last frost date, though indoor starting is recommended for best results in most climates.
Prune Purple Bell Vine in early spring to shape the plant and encourage bushier growth. Remove any weak or crossing stems and thin out crowded sections to improve air circulation. Light pinching of stem tips early in the season encourages branching and fuller flowering.
