Dangers connus

  • Although no mention has been seen for this species, at least one member of this genus has a root that is rich in saponins [2].
  • Although toxic, these substances are very poorly absorbed by the body and so tend to pass through without causing harm [65].
  • They are also broken down by heat so a long slow baking can destroy them .
  • Saponins are found in many plants, including several that are often used for food, such as certain beans .
  • It is advisable not to eat large quantities of food that contain saponins .
  • Les saponines sont beaucoup plus toxique pour certains animaux, comme les poissons; des tribus de pêcheurs en ont traditionnellement mis de grandes quantitié dans les rivières et les lacs pour droguer ou tuer les poissons [K].

Usages médicinaux

  • The root is alterative, diaphoretic, purgative and tonic [4, 61].
  • Although rarely used, this species can be employed in many of the same ways as soapwort, Saponaria officinalis [4].
  • It is a valuable remedy, used as an external wash, for the treatment of many skin diseases [4].

Autres usages

  • The plant contains saponins [4, 61].
  • Can these be used as a soap substitute? .

Culture

  • Requires a sunny position and a deep soil [1].
  • Lime tolerant [1].
  • Grows well in a dryish soil [1].

Propagation

  • Seed - we have no information for this species but suggest sowing the seed in a greenhouse in spring .
  • When they are large enough to handle, prick the seedlings out into individual pots and, if growth is sufficient, plant them out into their permanent positions in the summer .
  • If the plants are too small to plant out, grow them on in the greenhouse for their first winter and then plant them out in late spring or early summer .
  • Division au printemps ou à l'automne .
  • Les plus grandes divisions peuvent être replantées directement à leur place définitive, il vaut mieux mettre en pot les plus petites divisions et les cultiver sous chassis jusqu'à ce que les racines se soient développées .
  • Plantez les au printemps .
  • Basal cuttings before the plant flowers .
  • Harvest the shoots when they are about 10cm long with plenty of underground stem .
  • Rempotez les dans des pots individuels et gardez les sous une ombre légère sous chassis ou sous serre jusqu'à ce que les racines se soient bien développées .
  • Replantez les en été .
  • Root cuttings .

Réferences

[1] F. Chittendon. RHS Dictionary of Plants plus Supplement. 1956 1951.
Comprehensive listing of species and how to grow them. Somewhat outdated, it has been replaces in 1992 by a new dictionary (see [200]).
[2] Hedrick. U. P. Sturtevant's Edible Plants of the World. 1972.
Lots of entries, quite a lot of information in most entries and references.
[4] Grieve. A Modern Herbal. 1984.
Not so modern (1930's?) but lots of information, mainly temperate plants.
[50] ? Flora Europaea 1964.
An immense work in 6 volumes (including the index). The standard reference flora for europe, it is very terse though and with very little extra information. Not for the casual reader.
[61] Usher. G. A Dictionary of Plants Used by Man. 1974.
Forget the sexist title, this is one of the best books on the subject. Lists a very extensive range of useful plants from around the world with very brief details of the uses. Not for the casual reader.
[65] Frohne. D. and Pfänder. J. A Colour Atlas of Poisonous Plants. 1984.
Brilliant. Goes into technical details but in a very readable way. The best work on the subject that I've come across so far.
