More information
This variety shows traits typical of early hybrids. Flowers display a range of purple and violet tones, recalling old Gallica roses. Blooms are large and deeply cupped, while the shrub is comparatively small. Coloration varies markedly and can become rather muted. Vigor is moderate. The plant responds to increased fertilizer applications and to regular preventive spraying against disease.
Among David Austin roses, this cultivar exhibits moderate sturdiness. Wise Portia is adapted to dry, hot climates; under such conditions it shows good disease resistance. Flowers open dark magenta or pale crimson, then fade to dark pink, lilac, or purple, especially in hot weather. Blooms form loose rosettes and hold well when cut. Their large size and unusual coloration suit floral arrangements, though the blooms can at times outweigh the supporting branches. The bush is compact, with slender shoots and sparse foliage; leaves are dark green, bronze-red in spring. With attentive care it reblooms quickly.
