In the garden
A member of the Brassicaceae, Brassica napus 'Rnx5321'PBR sits within the oilseed rape group and is intended for both vegetable plots and ornamental beds. It forms discrete clumps of foliage before producing a succession of yellow flowers through the summer months, with blooms occurring from May to September. As a garden cultivar its contribution is primarily floral and seasonal rather than woody structure. Choose a site with full sun and some shelter; south-, east- or west-facing exposures suit it best. Soils should be loam or sand in texture, neutral to alkaline in reaction, and kept moist but importantly free-draining. The H5 hardiness rating means it is classed as hardy in most UK gardens, tolerating winter conditions common outside the most exposed maritime and upland sites. Plant it where both its flowering period and its role as a productive brassica can be put to use: alongside summer vegetable rotations, within informal orchard underplanting or as a short-term ornamental block in mixed borders. Because its yellow blooms run from May to September, it can bridge early-summer crops and later brassica sowings within the same season.
