Cardinal Climber

ANNUAL VINE

Summer/fall bloom
Frost tender

TO START OUTDOORS

In spring, wait until temperatures are above 50°F (10°C) both day and night before planting seeds in full sun in ordinary garden soil 4 to 6 inches apart and 1/2 inch deep. Firm soil over seeds and keep evenly moist but not soggy.

TO START EARLY INDOORS

Sow seeds indoors 4 or 5 weeks before last expected frost in individual 4 inch pots of seed starting mix. Cover 1/2 inch deep and keep warm and moist. After seedlings have several leaves, thin to the strongest seedling per pot. Provide a strong light source until seedlings are ready to plant outdoors. When spring weather has warmed, acclimate seedlings to outdoor conditions before planting outdoors. Thin or transplant seedlings 10 to 12 inches apart and several inches from supports when large enough to handle. Avoid disturbing roots.

GROWING NOTES

Be sure to erect well-anchored, sturdy supports at least 8 feet tall at planting time; strong netting, a fence or a strong trellis is needed to hold these vigorous and rapid climbers that bloom at midsummer. Note: seeds are poisonous; keep from kids and pets.
