Named for Elizabeth Strangman’s British nursery where it originated, ‘Washfield’ is regarded as the best subsessilis cultivar currently available. Adored by butterflies and bees, well-endowed, erect branching spikes house vibrant clusters of blue-violet tubular flowers, opening from small buds shrouded in dark calyxes. The bushy clump-forming base yields scented green foliage, which offsets gray-leafed plants to great effect and obliges heavier soil more so than most Catmints. Winterhardy perennial Height 60-70 cm Width 40 cm Spacing 40-50 cm (5-7 pc/m2) Flowering time VI-IX Site sunny to half-shade, medium moist rich soil.
