Cathedral Bells

TENDER PERENNIAL VINE

Summer/fall bloom
Usually grown as annual

FOR BEST RESULTS

Sow seed indoors in a warm place 6 to 8 weeks before night temperatures are reliably in the 50°F (10°C) range. Plant 2 seeds per individual 4 inch pot of seed starting mix. Maintain at 70-80°F (21-27°C). Keep moist but not soggy. Germination takes 10 to 21 days. Thin to strongest seedling per pot. Provide a strong light source until ready to go outside. When weather has warmed evenly, acclimate to outdoor conditions and carefully transplant 1 foot apart and 3 inches from supports.

TO START OUTDOORS

Seed can be sown outdoors once nights are reliably above 50° but only in areas with a long warm season. Plant in full sun 4 to 6 inches apart, ½ inch deep and 3 inches from supports. Firm soil well over seeds. When seedlings are well established, thin to stand 1 foot apart, so these vigorous vines have ample room to grow.

GROWING NOTES

Cathedral Bells need full sun and moist, well-drained soil. They bloom mid to late summer. Provide climbing vines with well-anchored supports at least 10 feet tall; use a sturdy trellis or arbor, or a wood or wire fence. Stems cling by branched tendrils that grow on the end of each leaf stalk.
