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 >>>

Propagation

Seed - we have no information for this species but suggest sowing the seed in a pot that is standing in its own depth of water in a greenhouse as soon as the seed is ripe if this is possible. Stored seed is likely to have a short viability. Prick out the seedlings when they are large enough to handle and increase the depth of water around the pot until the plants are covered by a few centimetres of water. Grow the plants on in a sunny position in the greenhouse for their first winter, increasing the depth of water as the plants grow larger. Plant them out into their permanent positions in early summer. Division in spring[56]. Cuttings of erect shoots in the growing season[56].
