What grey leaved plants can I put under a holly tree please ? , trunk is 5ft before branches start
Most grey leaved plants prefer sunshine. The furry leaves are an adaptation to cope with lots of heat. So they don't like being in shade although they can cope with it being dry. Silver leaved dead nettle (lamium) seem to like it under the dry shade of my oak tree.
You could try a green leaf that is frosted like Brunnera Jack Frost.
