Cultivation details

Requires a sunny position[11], succeeding in any moderately fertile well-drained soil[200] including limy soils[182]. This species is on the borderline of hardiness in Britain. It can tolerate occasional lows down to about -12°c, so long as it is not too wet. It is best grown against a warm, sheltered sunny wall[200]. The plant succeeds against a warm wall at Kew Gardens, where it has grown to a height of 8 metres, it also succeeds in more open conditions on the Isle of Wight[11]. The plant is often cultivated for its very ornamental, showy flowers[274]. 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].

I am interested to know that this plant grows in Britain. I have memories of it when I was a child in the desert mining town of Kalgoorlie in western Australia, where we had a small grove of the shrubs growing in a very dry hard soil. It has a peculiar aromatic smell that i remember well.

I live in Bexleyheath, Kent. For some years now I have tried to grow this plant without success I would grow the plant to about twelve inches bring it indoors for the winter. The next year the same would happen. However one year I built a pergalar at the end of my garden and encased in polycarbonate for the winter. Three years later the damn plant has grown larger than the structure and it has got ten buds (florets). The problem is that now it's got a spread of over eighteen feet. How do I prune it?

Of all the sites I looked at, yours was the only one to include germination information. thank you.
