[1] 'Ecolonia' was named after a nature reserve in Alphen aan den Rijn in The Netherlands where it was found and distributed by the Proefstation voor de Boomkwekerij in Boskoop before 2008 [2] Description'Ecolonia' typically grows to a height of 0.9–1.2 m. The terminal panicles are mauve-blue, complemented by silvery foliage [1] The shrub is also notable for its scent, and for the long period it remains in flower.
