There are edible flowers, and there are edible flowers that taste good. Sweet Alyssum is the second type, a generously blooming carpet of small buds that tastes like mustard greens.
The variety I have the most of is called “Snow Princess,” a vigorous variety that’s heat tolerant with white flowers; intensely fragrant and grows up to six inches tall and five feet long. They’re self-seeding.
All this time I’ve been using them as flower filler, pops of white delicate blossoms among larger cut flowers. Now, I’m putting them on salads as garnish you can eat. The best part about sweet alyssum is that it genuinely tastes great: like a mild mustard green, the family from which alyssum comes from.
