How about a mum that is grown for its foliage and not just for the flowers? 'Frosty' does this with its dark green, deeply lobed foliage spattered in white. The color elevates this plant to "unusual" status, having all season interest. When it flowers in fall this 12" tall mum displays abundant, dark-pink, spoon-shaped flower petals surrounded by a bright, sunny-yellow center. Plant in full sun with adequate moisture and good drainage.
