Dahlia aficionados will appreciate the 'Mystic' series with their signature dark, lobed foliage and vibrant colored blooms. 'Mystic Illusion Yellow' grows fast, two to three feet tall, and generally requires no staking. Its sunny yellow flowers stand out dramatically against the almost-black foliage, making it an excellent choice for cut-flower gardens. Pair with other sun-loving summer blooms in container planters and hanging baskets. Although many gardeners grow this perennial as an annual in the Pacific NW, determined individuals can try sheltering 'Mystic Illusion' under the eaves or in garages during the winter months. By the end of the second season, this variety may have viable tubers that can be dug and stored for the following year.
