The story
Sweet alyssum grows wild on Mediterranean sea cliffs. Lettuce and strawberry growers in California now plant it in strips through their fields, because the hoverflies it feeds lay their eggs among the aphids.
Planting
Press seed onto the soil surface in early spring; it needs light to sprout. Sun or part shade.
Growing
Shear it back by half when it tires in midsummer heat, water, and it blooms again until hard frost.
Harvest and use
Nectar for the smallest beneficial insects, a living mulch under taller crops, and a honey scent along the path.
What to watch for
It stalls in hot weather. It self-sows freely in mild climates.
