Beloved for its sweet honey scent, this easy, fast bloomer is one of the best attractors of beneficial insects and butterflies. Tiny insect predators that protect the garden from chewing insects need small, nectar-rich flowers, and sweet alyssum is a favorite. Perfect for cascading down walls or containers, as a low edging (esp. with cabbage family), or as a carpet under tall, relatively open plants like onions, garlic, orach, pole beans, podding radish and sunflowers. Succession-sow, spring to fall.
