I'll be moving into a new home shortly and the current foundation shrubs are overgrown, spaced, and trimmed unevenly. I was thinking of pulling them up and replacing them with winter gem boxwoods or something similar. My fiance however wants something that will flower in the spring/summer yet retain its leaves during the winter. The area in which they will be planted is partial to full shade. Will rhododendrons remain full in the winter or is there a better option? I surely don't want barren shrubs along my foundation. Your opinions are greatly appreciated, Thanks!
