TO START OUTDOORS
In late spring, once weather is warm and settled and nights stay consistently above 50°F (10°C ), plant seeds in a sunny, sheltered spot in well-drained, fertile garden soil 6 inches apart and ½ inch deep. Provide supports at planting time. Keep soil moist but not soggy while awaiting germination, which can be somewhat slow and erratic.
TO START EARLY INDOORS
Sow indoors 5 to 6 weeks before last expected frost in individual pots of seed starting mix. Cover ½ inch deep and keep warm and moist. Provide a strong light source until seedlings are ready for outdoor planting. Once nights stay consistently above 50°F (10°C), transplant outdoors, 6 inches apart, being careful not to disturb delicate roots.
GROWING NOTES
These plants grow best in a sheltered spot, out of the wind. Thunbergia germinates and grows slowly at first, then begins to twine and develop flowers at midsummer. It is a charming choice for hanging baskets, where the vines will grow up and form a pyramid of bloom (plant four seedlings in a 10 to 12 inch diameter basket and feed regularly). Or, grow the vines up a trellis or arbor for a lovely effect.
