The genus contains a single species, C. majalis, which is among the most useful ground covers for shade. These charming and richly fragrant plants have many bell-shaped white flowers in late spring and are beloved by everyone. In the garden, they spread diligently and will prosper in low light. They are often found near old foundations, where they proved more durable than the houses. Culture is the same as that used for all woodland plants--a woodsy soil (one rich in humus) and a location in shade or well-filtered sunlight. Lily-of-the-Valley is also excellent for forcing.
