Cultivation Details

Succeeds in a moist, well-drained circum-neutral soil in full sun[]. Succeeds in poor soils.
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[]. Buttercups growing nearby depress the growth of the nitrogen bacteria by means of a root exudate[]. When removing plant remains at the end of the growing season, it is best to only remove the aerial parts of the plant, leaving the roots in the ground to decay and release their nitrogen.

Propagation

Pre-soak the seed for 12 hours in warm water and then sow in spring in situ.
