Lily of the Valley

Convallaria
A small genus of groundcover perennials that are part of the much larger Liliacaea ( Lily ) family. They are deer resistant. Lily of the Valley can be used to line woodland pathways or as groundcover ...recommended to plant them 1 foot apart. They can be propagated from dividing the rhizomes during mid-autumn or early spring. A stem bearing 2 leaves grows from each rhizome eye. When dividing the clumps, be careful to leave at least 1 eye on each rhizome division piece which should then be planted at the same depth it was originally.
Insect pests and disease problems are rare, and they tolerate drought and tree root competition. Lily of the Valley is also deer resistant.

Convallaria keiskei
Similar to Convallaria majalis but is native to eastern Russia, Mongolia, China, Korea and Japan rather than Europe. It forms a groundcover perennial, reaching up to 1 x 4 feet.

Convallaria majalis ( Lily of the Valley )
A very attractive, very long lived, rhizomatous, fast spreading but not invasive perennial. After many years plants can spread to form a clump up to 1 x 4 feet in size though can be easily contained. It is a widespread native of Eurasia ( from the British Isles to Russia; south to the Alps to northeastern Turkey to the Caucasus )
The vertically-veined, broad-elliptical leaves, up to 12 x 4 ( rarely over 10 ) inches, are glossy deep green. The leaves are paired on the stem.
The strongly-fragrant, nodding, white, bell-shaped flowers, up to 0.3 inches wide, are borne on drooping racemes during mid to late spring.
They are followed by shiny orange or red berries up to 0.3 inches wide.
Hardy zones 1 to 7 in partial to full shade, preferring well drained, acidic, fertile, moist soil. Applying a layer of organic compost at the end of autumn is like rocket fuel for growth the following year. Propagation is from division, replanting the rhizomes shallow but firm during autumn.

  2. Unfortunately here in Maryland 99.9% of the Lily of the Valley I see are the traditional form ( which is still nice ). I have seen some 'Albostriata' in private gardens but not for sale. Even Kurt Bluemel in Maryland only carries the traditional form and their selection of rare perennials is massive.
    In Canada and New England ( and especially in Europe ) the above cultivars may be more available in the landscape trades.
