An old-fashioned perennial that’s fallen slightly out of favor because it can become quite aggressive, lily of the valley still is a darling spring bloomer. Its tiny white bells dangle on long stems and have a sweet scent in mid-spring. Though the flowers will only bloom for about three weeks before developing into small reddish berries. Plant it in a mostly shaded area where it has room to spread as a ground cover, but not too near other perennials.
