The plants do very well underplanted under a canopy of trees, and planted among other shade garden plants such as ferns.

Lily of the valley grows via a rhizomatous root system underground, easily producing new plants and propagating in this manner.

The roots and underground stems spread and grow under the surface of the soil. They also also produce upright stems which develop into new plants.

Lily Of The Vally Pips

The new upright stems or shoots that come up from the ground in spring are known as pips.

These pips remain connected to the other plants by their root system. However they are easily separated and can be dug and transplanted to another area.

The pips will open to reveal a Lily of the Valley stem with flowers, along with two large green leaves which grow from the base of the flower stem.

Lily of the Valley blooms grow on fairly short stems which are approximately six to eight inches in length.

There are numerous tiny flowers which grow along each stem, and they nod in a downwards direction on the stem.

There are also cultivars with pink flowers, although these varieties are less common.
