Q. My boxwood shrubs turn a dull bronze color in the winter. Are there any varieties that stay green all winter?
A. Many varieties of boxwood retain their green color during the winter months; others will turn off-color. The degree of color change in some species will vary between winters. Some boxwoods that are prized for retaining their green color throughout most winters are 'Wintergreen', 'Green Velvet', 'Green Mountain', and 'Glencoe'.
