SIZE: Height: 3-4 feet; Spread: up to 18 inches.

GROWING GUIDELINES: For early blooms, buy your transplants in spring, or start seeds indoors 3 to 4 weeks befor the last frost. Plant seeds 1/4 inch deep. Plant outside 1 to 2 weeks after the last frost date. Seed can also be sown directly into your garden right around the last frost daye. Space your transplants 6 to 12 inches apart. Pinch off stem tips early in the summer to promote branching and more blooms. Push sturdy pieces of twiggy brush into the soil around the young plants to support the stems as the grow. Stake individual stems as needed. Or, they can be left to sprawl, they will send up more flowering stems.
