An excellent cut flower produces a wonderful mass effect as a bedding plant, strongly scented. Use a light weight potting soil and sow seeds 1/4 inch deep. Since pots and containers dry up quickly so do not forget to water frequently. Full grown plants reach 12 inches or more in height, depending on variety. Transplant 30 cm apart. Deadheading sweet William after each blooms lengthens the plant life and blooming season.
