Most bulbs can’t take moist soil, but camass lily (Camassia leichtlinii 'Caerulea') is an exception. This heirloom beauty dates to 1853 and goes by a host of names, including wild hyacinth, quamash and Leichtlin’s camass. It’s a must-have bulb for spring color because it brings strong blue tones to the garden during the time between spring daffodils and tulips. Flowers open in spikes surrounded by deer- and rabbit-resistant leaves. Plants naturalize readily to form drifts of color when conditions are right. This beauty grows 24 to 30 inches tall. Hardy in Zones 4-8.
