The Ultimate Lily of the Valley Growing Guide


Lily of the Valley (Convallaria majalis) is a delicate and pretty plant that produces a delightfully fragrant white flower. While its name would lead you to believe that Lily of the Valley belongs to the lily family, it is actually part of the asparagus family!

It’s a hardy plant that quickly covers the ground and thrives in the shade. Lily of the Valley is a good solution for homeowners who don’t want to mow the grass on a regular basis, but who still want a robust green garden. Dotted with curved wooden benches, a birdbath or two, and some colourful flower beds, Lily of the Valley looks lovely and smells fantastic. What an elegant and low-maintenance alternative to grass!

What Is Lily of The Valley?

Lily of the Valley is a woodland flowering plant that is native to Asia and Europe but has been imported around the world. It is often considered an invasive species in North and South America because it grows quickly and will overtake other native vegetation. It has bell-shaped white flowers that emit a sweet fragrance, which makes them a popular choice in any garden.

Also referred to as May Bells, Mary’s Tears, and Our Lady’s Tears, it can be found as an ingredient in perfumes under the moniker muguet (its French name).[1] It was used as an ingredient in medieval medicine, often listed in archaic recipes as glovewort because it was used to treat hand maladies. Lily of the Valley is densely packed with cardiac glycosides, which can cause heart failure in both humans and animals. Exercise caution when planting near children or curious pets.

Common Lily of the Valley cultivars include[2] Rosea, which produces flowers with a slight pink tinge. For white edges, choose Albomarginata, or go with Albostriata for whiteish stripes that fade to green. For a more golden yellow colour, plant Fernwood’s Golden Slippers. Aureovariegata, Hardwick Hall, and Crema da Mint all feature light green stripes across the foliage.

Dig a hole that is double the width of the root ball, and add some blood, fish and bone meal, working into the soil. Add the plant to the hole and cover with soil so that the plant is at the depth it was when it was in the pot. Pat the soil down gently, and water well.

If you are planting roots or pips, soak the pips for at least 30 minutes. Dig a hole just slightly larger than the roots and add the roots to the hole (there is no top or bottom to the roots).

  • Southern Blight causes tan ball structures to grow near the base of the soil, and causes your plants to wilt and die.
  • Anthracnose and Aureobasidium causes water-soaked spots that then scale up to reddish brown spots all over the leaves. To prevent, water the soil instead of the plants.
  • Rust – Rust causes small yellow spots to develop on the tops of the leaves, and brown spore masses to form on the undersides.
  • Foliar nematode – The veins turn brown and yellow, and the plant must be destroyed.
