Sanguinaria canadensis, commonly known as Bloodroot, is an early spring ephemeral whose showy white flowers open on sunny days when the temperature exceeds 46 degrees, and close as the temperature falls or daylight fades. It is an important nectar source for early emerging native bees, growing 8 to 10 inches tall under deciduous trees. Blooms are followed by distinctive, lobed leaves that make for considerable garden interest until the plant goes dormant in mid-summer heat.
