Other Uses

Disinfectant;  Repellent.

The crushed leaves have been rubbed on the face and hands as a protection from mosquitoes[257].

Cultivation details

Prefers a damp peaty sandy soil in a cool damp shady position[1, 42, 200]. Requires a moist neutral to acid soil[200]. The dormant plant is hardy to at least -25°c, but new growth in spring can be damaged by late frosts[187]. Plants only produce their fruit in warm seasons in Britain[200]. They have creeping underground stems and form dense colonies[187]. This species is closely related to C. andrewsiana[188].

Propagation

Seed - best sown as soon as it is ripe in a cold frame, it usually germinates in the spring[200]. Stored seed should be sown in late winter or early spring in a cold frame[164]. It sometimes germinates within 1 - 3 months at 15°c, but may take a year. The seed should be completely separated from the fruit and should only just be covered by soil[164, 200]. If the seed has been sown thinly enough, then it is possible to leave the seedlings in the pot for their first growing season, dividing them after they become dormant. Make sure to give them liquid feeds at intervals through the spring and summer. Otherwise prick out the seedlings into individual pots when they are large enough to handle. Plant out in late spring or early summer at the beginning of their second or third years growth. Division in spring as new growth is just commencing[200].

Just curious about your entry on Clintonia (plant of the northeast US). I have found that here we call it bluebead, not bluebeard. I'm not sure if it's a typo-error or just a difference in translation. But thought I'd bring it to your attention. Looks like a nice page full of great info.

Correct Family name: Convallariaceae or Liliaceae? We were told as children that the fruit is poisonous. Do you know if this is correct?

There are some reports that the fruit is mildly toxic and that eating it can cause mild gastric upsets. These same reports also state that the leaves are edible.
