Need name for shrub
This spring a local retailer planted several green and white, small leafed, moderately sized shrubs. It does not seem to flower. It's taller than wide, standing about 4 feet high by 3 feet wide. It grows kinds of spikey looking, with it's branches sticking out like a porcupine. These shrubs don't get much attention, but they look healthy and have grown well in spite a very hot summer and in the blazing sun all day. Does anyone know what shrub this could be? I can't even guess it's name. Thanks much.
