Euonymus alatus 'Compactus' (Dwarf-Winged Burning Bush)


Michael's Opinion

A very popular garden plant known for its spectacular red autumn colour. It can successfully be maintained as a rather dense hedge. Tolerant of dry soils in full sun once established. Also fairly pollution tolerant lending itself to commercial applications. I think it tends to be overused because its so reliable however it does make a nice border especially when mixed with other plants for contrast. There seems to be a little confusion around the correct spelling, Hortus Third lists the plant as E. alata 'Compacta'. I have decided to use E. alatus 'Compactus' since it appears more frequently.
