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.

Other Uses

This species is planted for dune stabilization and for soil and water conservation[266]. Carbon Farming - Agroforestry Services: nitrogen, contour hedgerow, windbreak. Fodder: bank.

Caragana microphylla prefers a continental climate with its hot summers, cold winters and usually a clear movement from one season to another. The dormant plant can tolerate temperatures down to at least -30°c, but in more maritime climates it is often tempted to come into growth early and this new growth can easily be damaged by late spring frosts[200 ]. Prefers full sun and a light sandy dry or well-drained soil[1 , 11 , 200 ]. Dislikes damp conditions[1 ]. Does not require a rich soil, succeeding on marginal land[11 ]. Caragana microphylla is a polymorphic species and in some cases with transitional forms[266 ]. Hybrids between this species and Caragana korshinskii may occur where these species are sympatric[266 ]. Plants in this genus are notably resistant to honey fungus[200 ]. This species has a symbiotic relationship with certain soil bacteria, these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby[200 ]. Climate: boreal to warm temperate. Humidity: arid to semi-arid. Carbon Farming - Cultivation: regional crop. Management: standard, coppice.

Propagation

Seed - best sown as soon as it is ripe in a cold frame[200 ]. It usually germinates in 2 weeks[K ]. Stored seed should be pre-soaked for 24 hours in warm water then sown in a cold frame[78 , 113 , 200 ]. If the seed has not swollen then scarify it and re-soak for another 12 hours before sowing[138 ]. Germination usually takes place within 2 - 3 weeks at 20°c[138 ]. Good percentage[11 ]. As soon as they are large enough to handle, prick the seedlings out into individual pots and grow them on in a greenhouse for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Cuttings of half-ripe wood, 7 - 10cm with a heel, mid summer in a frame[113 ]. Layering in spring.
