If you're looking to add a tropical flare to your landscape with a very cold hardy and colorful beauty that can handle temperatures down to -40F, the 'Dark Mystery' Hardy Hibiscus is a North American native perennial flowering shrub that wows with both foliage and enormous flowers that will do just that, even more so than a tropical hibiscus would! A little later to bloom than other cultivars, the huge, dinner plate size white to very soft-pink flowers of Dark Mystery begin coming mid summer and continue nonstop through early fall. Each flower has a dark cherry red eye from which dark pink veining extends through the petals. But where this variety gets its name is from its handsome deep wine-purple foliage, which serves as the perfect backdrop to showcase the flowers. Although the foliage is a little later to emerge in spring than some other types of plants, once it starts emerging the growth is rapid. The large, maple-like leaves are broadly smooth and form a full, billowy look on mounding plants that might reach 5.5 feet tall and equally as wide. A captivating specimen, grouping or hedge in the landscape. Especially nice around patios, pools and around other outdoor sitting and living spaces. Get all the details below
