Ruby Colonnade Is a Superb Holly for Form and Foliage Color

Virtues: Don’t expect berries from this male holly, but it has enough other outstanding attributes to make that a non-issue. An evergreen bred at the University of Georgia, it has excellent form all year as well as some added color when new foliage emerges. New leaves are deep red in hue, before they shift to bright green. The foliage is very dense, with a luster that highlights the shrub’s overall texture. This holly is easy to shear or shape into topiary, though it maintains a pleasant pyramidal shape on its own, for those who do not want to prune.
