Japanese catmint (Nepeta subsessilis) 'Washfield'
Container size 2L
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.
