Paint a 28-inch-long window box and add frost-tolerant mums and flowering kale for bold color all the way to season's end. We used two types of flowering kale to contrast the warm-toned mums in this arrangement. Keep this autumnal window box in a sunny spot for the longest life.
A: Flowering kale (Brassica oleracea 'Red Sunset') — 2
B: Chrysanthemum 'Beth Violet' — 1
C: Chrysanthemum 'Anna Yellow' — 2
D: Flowering kale (Brassica oleracea 'Redbor') — 1
Flowering kale's leaves come with beautiful variegations in pinks, purples, and reds that blend beautifully with changing autumn foliage. 'Red Sunset' is a compact variety with a bright red center and dark green outer leaves. Plant flowering kale in mid-fall—too hot of temperatures can fade the leaves' color.
Planted for their spectacular flowers that come in a variety of colors, shapes, and sizes, mums are the perfect fall-blooming plant. These showy plants bloom in late summer and continue into the fall, creating dense mats of color. 'Beth Violet' features dense, fuchsia blooms.
With almost every color of the rainbow available, chrysanthemums can enhance any garden or container. Mum bloom shapes and sizes are quite spectacular, with a wide range of sizes including the common small cushion mum to the giant spider mums. 'Anna Yellow' features yellow blooms with yellow centers.
Flowering kale is one of the few plants available to add a fresh burst of color and life to the fall landscape. Brassica 'Redbor' offers ruffled leaves in a rich, dark purple shade that mixes well with just about everything. In this arrangement, the deep, subdued color of the foliage makes the bright mums pop.
