Description
Small, compact, relatively hardy (min. -12 °C), evergreen shrub (H 1-1,5 m, W 1-1,5 m). Leaves broadly ovate (1,5-2 cm), with a serrate margin, smooth, glossy, dark green. Flowers tiny, in dense, oval panicles (up to 4 cm), light blue. Flowering period: May-July. Attracts butterflies and bees. Requires sufficiently drained, light, fertile, humus-rich soils, in sunny, warm, sheltered sites. Not reliably hardy in central-european continental climate, needs winter protection.
