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.

Requires a well-drained moisture retentive soil and a very sunny position[200]. Succeeds in dry soils. Highly fertile soils can promote soft sappy growth which is frost tender[200]. Trees tolerate a high pH, saline soils, high winds and drought[200, 238]. They also succeed in poor soils[238]. Trees prefer a more continental climate than Britain[11] and when dormant are hardy to about -20°c in such a zone[200]. They are only hardy to about -10°c in the maritime climate of this country[200]. The young growth in spring, even on mature plants, is frost-tender and so it is best to grow the plants in a position sheltered from the early morning sun[K]. They succeed on a sunny wall at Kew[11], and also in a more open but sunny sheltered position there[K], but only really succeed outdoors in the mildest areas of Britain[1]. If killed back to the ground by a severe winter, plants can often resprout from the base[200]. The form 'Rosea' is hardier and more compact, succeeding even in the drier parts of Britain if given some protection[11]. Plants are quite tolerant of pruning and can be fan-trained for growing on a wall. Any pruning is best done in late winter or early spring[202]. Often grown as a summer bedding plant[1]. Quite tolerant of being transplanted[200]. Plants often produce suckers[200]. 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]. Special Features:Attracts birds, Attractive foliage, Not North American native, Invasive, Fragrant flowers, Blooms are very showy.

Propagation

Seed - pre-soak 24 hours in hot water and sow March/April in a greenhouse or sow as soon as it is ripe in a cold frame[113]. Germinates in 2 - 3 months at 19°c. Scarification helps[133]. There are about 11,000 seeds to a pound, about 25 - 33% of which germinate[227]. Prick out the seedlings into individual pots of fairly rich soil when they are large enough to handle and grow them on in the greenhouse for at least their first winter. Plant out in late spring or early summer and consider giving them some protection from the cold for their first winter or two outdoors[K]. Root cuttings, late winter in a greenhouse[113, 200]. Cuttings of half-ripe wood, July/August in a frame[200]. Suckers planted out in late winter[200].

I find that the seeds will germinate in about 3 days not months on a full sun window sill if scarified, soaked for 24 hours and very lightly covered with sand or similar. I then have problems with younge plants though as the leaves seem to crinkle and drop and the plant dies. I think this is because of a lack of tollerence of direct sun in the early stages. I've yet to get any beyond 3 months indoors. My last plant from my last seed is hanging in there though on an indirect sill.

I have had a lot of luck with the plants self sowing from the parent tree. Let them grow for 1 year then pot them up in a 6 inch pot sell them at the local market about 6.00 each.

Hi. We have a young Albizia (red flower) that is only one year old. This season (Early Summer down here in New Zealand) the tips of the leaves have turned white. Do you know what may be causing this, and what we need to do? Thanks. Regards, Leonie & Ben Moore

My Albizia is planted in quite an exposed site and at a relatively high altitude in mid-Shropshire. Contrary to the usual advice, it has been subjected to some serious frost. The plant is about 7 years old and has developed into a shapely small tree. It has flowered for the last three years, although not as profusely as I would want. However, it has got better each year so patience is rewarded.

My experience with this tree is that it is hardy to at least zone 6 if not colder.
