Taxonomic History

Elegant Pendant Bells

This twining vine reaches 10-15 feet with heart-shaped, softly hairy leaves. The flowers are the jewel: pendant, tubular bells 1.5-2 inches long, in deep, velvety purple to nearly black, with a slightly flared mouth. They dangle gracefully from the stems on long pedicels, appearing from late spring through fall. The darkness of the blooms is rare and mesmerizing.

Purple Bell Vine thrives in full sun to partial shade with rich, well-draining soil and regular moisture. Provide support for twining stems. Frost-tender (zones 9-11); widely grown as an annual vine in cooler climates, reaching 6-10 feet in a season. Pinch to encourage branching.

Sophisticated Vertical Accent

Use on trellises, obelisks, and arbors where the pendant bells can be appreciated at eye level. The dark flowers contrast beautifully with silver, chartreuse, or white companions. Excellent in containers with a support. A refined, unusual vine for gardeners seeking something beyond the ordinary.
