Quote....."Euonymus kiautschovicus, sometimes commonly called spreading euonymus, is native to Japan. It is a broadleaf evergreen to semi-evergreen shrub that typically matures in a rounded form to 8-10' tall. Greenish-white flowers bloom in 2-4" wide cymes in summer (July-August). Flowers are attractive to bees. Pink fruit capsules with red seeds mature in November.
Euonymus kiautschovicus was formerly known as Euonymus patens.
'Manhattan' is a cultivar that was discovered in Manhattan, Kansas. It has glossy, broad-elliptic, deep green leaves (to 2 1/2" long). It typically grows in an upright rounded form to 4-6' (less frequently to 8') tall."......... End quote.
However, with only one pic and no indicator of the size of the leaves, size/growth habit/colour of the seed capsules etc etc ..I still say it is difficult to be 100% sure which Euonymus sp it is.
