ℹ Colour Guard Yucca -This dramatic architectural Evergreen plant is one of the most beautiful variegated yuccas on the market. Its sword-shaped leaves bear bold central stripes of bright canary-yellow against a rich celadon edge. In winter, margins are tinged pink, and the entire yellow stripe turns rose-colored on many of the leaves, lasting through early spring. Branched clusters of nodding, creamy-white bells open in mid-summer on stout stems that reach 6 feet tall.
