Fosters Holly (Ilex x attenuata 'Fosters #2') would be my guess. But need a close up of leaf to be sure.

Thanks for the info. About as I expected to learn-lots of substandard trees in substandard locations. One thing jumps out when discussing such trees-the inaccuracy in thinking that no fast-growing tree can be a long-lived tree. Such clearly does not apply in the coniferous world. Beyond the obvious case here, many eastern species-white pine, red pine, hemlock, Norway spruce, many larch, all have fast growth and long lives as part of their genetic potential. +oM

Redwood sorral, ferns, hellabore, My redwood drops a lot of leaves, but the hellabore does well.

Cedar-of-Lebanon can be silvery also. In fact it often develops a grizzled appearance to the foliage with age, with there being silver on the top side of the sprays while the rest remains mostly green. And there are also all silver or gray variants, same as with Atlas cedar and Himalayan cedar.
