In the garden

Bulbinella gibbsii originates from New Zealand and is best appreciated in stonework and raised alpine beds where free-draining conditions prevail. It is a perennial suited to rock gardens and alpine gardens, offering seasonal interest when it flowers from May to July. Position plants where they receive full sun or light afternoon shade and plant into sandy or rocky, freely draining soil. Keep soil moisture moderate — avoid heavy, moisture-retentive loams — and choose sites from sheltered to exposed depending on other planting. These conditions mirror its native preference for open, well-drained ground. In a UK setting place Bulbinella gibbsii in gravel pockets, crevices or the front of an alpine scree so it sits comfortably among stone-loving companions. Its flowering period from May to July provides a predictable seasonal element in a rockery, and locating plants where soils drain quickly helps preserve their long-term vigour.
