Butterfly Flower (seed)
Start inside 8-10 weeks before planting out, in peat pots. Cover seed lightly, provide light and cool conditions (10-24 degrees C). May also be direct seeded outside in early spring or early autumn. Transplant when plants are still small in early spring. Space 24 inches in a permanent spot.
These plants hate to be moved or divided. Full sun to light shade and soil. Pinch back plants when 6 inches tall to encourage branching.
