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 >>>

Our new book Edible Shrubs is now available.

Edible Shrubs provides detailed information, attractively presented, on over 70 shrub species. They have been selected to provide a mix of different plant sizes and growing conditions. Most provide delicious and nutritious fruit, but many also have edible leaves, seeds, flowers, stems or roots, or they yield edible or useful oil.

Cultivation details

We have very little information on this species and do not know if it will be hardy in Britain, though judging by its native range it should succeed outdoors in many parts of this country. The following notes are based on the general needs of the genus. Prefers a moist, well-drained rather light soil, thriving in semi-shade[1]. Grows well in a woodland garden or peat bed. Plants seem to be immune to the predations of rabbits[233].

Propagation

Seed - best sown as soon as it is ripe, the seed rapidly loses viability if it is allowed to become dry[129]. Surface sow and keep moist, it usually germinates in 1 - 3 months at 15°c[164]. Germinates in spring according to another report[129]. Two months warm, then a cold stratification improves the germination of stored seed[134, 164]. Seedlings only produce one leaf in their first year of growth[175] and are very prone to damping off[129]. This species is a biennial and probably germinates more easily than the perennial species.
