Alyssum makes a great cover crop for weed suppression and for attracting beneficial insects. Its flowers attract predatory wasp species that feed on caterpillars, aphids, and other pest insects.
Alyssum adds carbon to soil, and it is a winter hardy flower that can be set out in early spring. In frost-free climates Alyssum can be also grown throughout the fall and winter.
This cover crop likes sunny climate but does not tolerate well prolonged dry periods.
