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 - best sown as soon as it is ripe in a cold frame[200]. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Division in spring[200]. Basal cuttings in spring[1]. Harvest the shoots when they are about 10cm long with plenty of underground stem. Pot them up into individual pots and keep them in light shade in a cold frame or greenhouse until they are rooting well. Plant them out in the summer. Layering in moist sand, it forms roots at the nodes[200].
