Cultivation Details

Since this is a woodland species it should succeed in semi-shade[K]. The following notes are based on the general needs of the genus. An easily grown plant, succeeding in any moderately good garden soil but preferring a position in full sun[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].
