Use: The brightly-colored dense clusters of white, pink, rose, red, purplish, or bicolor flowers made this an old-fashioned gareen favorite for the front of the border or the rock garden, for massing, or as edgings along pathways. Sweet William is often planted with trailing plants like lobelia and alyssum along the edge of raised beds.
Culture: Full sun is best and good air circulation is necessary, If the plants are given adequate light and water, they will bloom again the next year, but with smaller blooms. You can prevent the plant from going to seed by removing spent blooms. Overwatering and poor drainage can make the plants susceptible to rust. The plants may not survive wet winter soil.
