Seed To Bloom:
Recommended. Sow in pots 6-8 weeks before planting out. Keep at 65-75°F. Keep pots evenly moist but never saturated with water.
Sow in place after last frost in areas that have longer growing seasons, such as zones 9-10.
WHEN TO SET OUTSIDE
About 2 weeks after last frost, when temperatures remain above 40°F.
PLACEMENT & CULTIVATION
Cup and saucer is an elegant plant for trellis and arbors with beautiful leaves and stems and unique flowers. Plant in a warm, protected southern exposure in short-season gardens; some afternoon shade is tolerated in hot climates. Wait to plant until the night temperatures have warmed, generally 2-3 weeks after frost danger. As the plant matures, the tendrils cling to any rough surface and climb quite tall; pinching to control size is recommended. The flowers bloom starting in midsummer and continuing into late fall and make beautiful cut flowers. If growing in containers, select a large container that drains well and use a rich, well-draining potting mix.
Water regularly but do not allow soil to remain overly moist.
Not particular about soil pH.
Mix in 2-4" of compost prior to planting and topdress with another inch midseason.
Diseases & Pests:
If humidity levels are low, these vines are susceptible to attack from red spider mites and aphids; prevent this problem by regularly misting your plants or hosing them down.
When to Cut for Bouquets:
Cut when freshly opened. Dip stem ends in boiling water briefly.
