These old-fashioned favorites are a real treat in midsummer when they bloom in profusion and brighten the entire garden.

TO START OUTDOORS
In late spring, once weather is warm and settled and nights stay consistently above 50°, plant seeds in a sunny, sheltered spot in well-drained, fertile garden soil 6 inches apart and 1/2 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 1/2 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°, transplant outdoors, 6 inches apart, being careful not to disturb delicate roots.
