Flowers are as attractive as they are good to eat.
Fertilize with a balanced organic fertilizer in spring to encourage more flower development. Sow seed outdoors after the last spring frost. You can find an assortment of different flower colors and shapes, also cultivars with variegated foliage. Spray aphids with insecticidal soap. Harvest the peppery leaves and flowers for salads, vinegars, and cheese sandwiches.
