From Johnny's Selected Seeds:
"Thin, flat leaves with delicate garlic flavor.Attractive white flowers in midsummer, in the second year of growth. Flowers make a great addition to bouquets. The budded flower stalks are sold as "gow choy" in Chinese grocery stores.
Edible Flowers: Pull the florets apart and sprinkle on salads, dips, sauces, soups, stir-fries, and pizza. Great as an addition to potato salad. Flavor is of mild garlic."
