Please donate to support our ‘Plants to Save the Planet’ Project. The Project is directed at enabling designers of ‘carbon farms’ and ‘food forests’: agroecosystems of perennial plants, to choose the most appropriate plants for their requirements and site conditions. We are working on a subset of plants in the PFAF database identified as having the most potential for inclusion in such designs. We are adding search terms and icons to those plants pages, and providing a range of search options aligned to categories of plants and crop yields, with Help facilities including videos. More >>>

Other Uses

Can be used as a ground cover plant in a sunny position or light shade[188, 197]. It requires weeding for the first year or so[197]. They are best spaced about 45cm apart each way[208]. Plants have not been a reliable ground cover in Cornwall, often dying after flowering, though they usually self-sow[K].

Cultivation details

Thrives in any damp soil in a shady position[1, 111] or in full sun[200]. Plants are hardy to about -25°c[187]. The sub-species P. grandiflora pyrenaica has larger flowers and is found wild on acid soils whilst the type species is usually found on alkaline soils[187]. Plants tend to be short-lived, often dying out after flowering heavily in the summer[208]. Fortunately, they will usually self-sow freely[K]. Most plants are hermaphrodite but sometimes male plants are found.

Propagation

Seed - sow in mid spring in a cold frame. When they are large enough to handle, prick the seedlings out into individual pots and plant them out in the summer. If you have sufficient seed then it can be sown outdoors in situ in mid to late spring. Division in spring or autumn. Very easy, larger divisions can be planted out direct into their permanent positions. We have found that it is better to pot up the smaller divisions and grow them on in light shade in a cold frame until they are well established before planting them out in late spring or early summer.

There is at least one medicinal use. This blurb is from http://www.fleuroselect.com/goldmedal/details.aspx?id=1026&lang=en " It goes by the common name of ‘self-heal’ due to the fact that the foliage of this plant was used as a remedy to stop bleeding in the Middle Ages. " The degree of the styptic or coagulative effect, or even which it does, is unknown to me. There are numerous other possible(claimed) medicinal uses of the Prunella.
