Convallaria is a rhizomatous genus with only one species (Convallaria majalis) or according to others, three closely related species (additionally Convallaria keiskei and Convallaria montana). There is no agreement about which family to assign to it. It was originally considered to belong to Liliaceae, then moved to the family Convallariaceae. This latter family is not recognized by the Angiosperm Phylogeny Group II which redirects the genera once assigned to it to a broader Asparagaceae or a narrower Ruscaceae. This species is often found in lists of bulbs that can be grown in the shade. It is reported that potted plants are easily forced into flower after vernalization at 0 to 2 °C for 12 to 14 weeks.
Convallaria majalis is commonly called Lily of the Valley. It bears sweetly scented white bell-shaped flowers on terminal racemes in the spring. The Latin name breaks down to 'of the valley' and 'May', which links with another common name "May lily". First two photos taken April 2007 by Jay Yourch. Remaining photos by David Pilling show a ripening fruit, shoots and flower details.
Photographs of seed. Photo 3 shows the same seed as photo 2, a couple of months later, apparently the seed has formed a bud and is waiting for another Winter before starting to grow. Confirmation of that is provided in the last photo which shows the seedlings the next year.
Photos below show forms that are different. The first one shows unusual variegated leaves and was photographed July 2007 at Plant Delights Nursery by Jay Yourch. The second photo taken by Giorgio Pozzi May 2008 is of a variety with pink flowers. Flowers are the same size as the white form and also smell the same. The third photo from Hans Joschko also is of a plant with pink flowers.
