You certainly can. Each bulb

You certainly can. Each bulb produces a cluster of leaves. Just wait until the leaves are at least 6 inches tall, then you can harvest the outside leaves of the clump, leaving about 2 inches of leaf at the base, which helps the plant to regrow during the season. You can harvest a few times during a season; avoid older, yellowing leaves. Flowers may take as long as July to appear; the flowers themselves are edible, but the flower stalk is sort of woody, so should be discarded. If you won't be eating the flowers, cut the flower stalk off at the base once the flowers have finished blooming but before they go to seed (or, if you don't mind not having flowers, cut the flower stalk as soon as you see one start to develop).
