How to Grow Lily of the Valley Flowers

Botanical Name: Convallaria majalis

Fragrant lily of the valley flowers are a delight when they bloom in spring. But why wait? These types of lilies are easy to force into bloom indoors in the middle of winter.

The sweetly scented clusters of nodding bells are nestled between pairs of broad, pointy tipped leaves. Once the flowers fade, they're followed up by a show of red berries.

Don't let this lily's delicate appearance fool you. This hardy plant is a vigorous grower. It spreads quickly from rhizomes and will need to be potted up or divided each year.

You'll find lily of the valley plants for sale in nurseries and online florists' delivery sites already potted or shipped bareroot, ready for planting.

How to Get Lily of the Valley to Bloom Again

Beautiful lily of the valley flowers will bloom for about 4 weeks, then can be brought back into bloom the next year. Here are the steps:

  1. When flowers die, keep soil lightly moist and give your lily indirect sunlight until it goes dormant, typically in late summer or fall.

  2. Wait till the foliage turns yellow and withered, then cut it back. Don't pull the leaves off with your hands. Use sharp scissors or pruners to avoid damaging the rhizome. Put the dormant plant in a cool, dark spot giving it just enough water to prevent the rhizomes from drying out completely.

  3. Dormant rhizomes can be restarted in winter or spring. This is a good time to divide them. Pot 5-6 rhizomes together for an attractive planting, using fresh soil. Place rhizomes horizontally, root-side down and top with just enough soil to cover the rhizome. Put the pot back in a warm, bright spot (out of direct sun) and keep the soil lightly moist. Blooms should appear in 6-8 weeks.

CAUTION: All parts of lily of the valley are highly poisonous to people and pets.
