Helping You Become a More Successful Gardener
CHRYSANTHEMUM x morifolium 'Yorock'(ROCK) PP18275
Decorative Chrysanthemum, Spray Chrysanthemum
Developed for the cut flower trade, Rock chrysanthemum produces sprays of double, dusty-red blossoms on sturdy, upright, 36- to 40-inch (90 to 100 cm) stems. The 3-inch-wide (7 cm), many-petaled blooms appear in autumn under "natural" conditions, but greenhouse-grown specimens can be brought into bloom at other seasons, with plants flowering approximately 8 weeks after 2 weeks of "long nights" (13.5 hours or more). This vegetatively propagated mum was introduced by Yoder Brothers of Barberton, Ohio.
C. × morifolium originated in eastern Asia, where this herbaceous perennial has been cultivated and bred for many centuries. Its many cultivars are grown for their showy blooms, which are borne above clumps of fragrant, deeply lobed leaves.
Like most mums, Rock thrives in full sun and a fertile, well-drained growing medium.
