It is a good idea to plant Lilies-of-the-Valley along a walkway or in raised containers which you regularly pass by, so you can enjoy their strong fragrance every time you pass by.
Grow Lilies-of-the-Valley in areas that are moist and well drained, in full or partial shade, in leafy, fertile humus-rich, moist soil. In autumn top-dress them with leaf mold.
If you want to propagate them sow seed in containers in a cold frame as soon as they ripe, removing the flesh from the seeds before sowing them. You can also propagate Lily-of-the-Valley by separating the rhizomes in autumn, keeping them moist until established.
If you want a fragrant indoor display just lift and pot up some rhizomes in autumn and force them gently or allow them to grow at their own pace. Replant them out after flowering.
An important note: All parts of Lilly-of-the-Valley are poisonous if ingested, so be careful about their attractive, fleshy berries that appear after flowering and can be ingested by children. A better way is to remove berry stalks before they ripen.
