Culture

Best grown in humusy, fertile, consistently moist, well-drained soils in full sun. Tolerates very light shade, and appreciates some afternoon protection from the hot sun in southern climates. Pinch stems back as needed from late spring to mid summer (e.g., Memorial Day and the 4th of July) to control height and to encourage bushy vegetative growth. For best bloom, feed plants several times during the growing season. Cut plants back to 6” after flowering and mulch (e.g., straw or evergreen boughs) for winter. Divide as needed (usually every 2-3 years) in spring or fall. It should be noted that in cold winter climates such as the St. Louis area, plants given winter protection will usually survive, but not always. Winter hardiness can vary considerably from year to year and from location to location within the same hardiness zone. Notwithstanding the preceding culture recommendations, garden mums are frequently purchased in pots in late summer each year and grown as fall flowering annuals to supplement or replace summer annuals, rather than as permanent additions to the garden.

Noteworthy Characteristics

MARILYN is a clump-forming, fall-blooming garden mum with flat decorative capitulum form (flattened, double flowerheads with short ray florets). MARILYN is part of the Prophet Series by Yoder. This is a compact, mounded, well-branched hybrid that typically grows 1.5-2’ tall and features white flowers. Profuse bloom covers the plant in fall from September to frost. Thick, aromatic, lobed, dark green leaves (to 3” long). MARILYN is one of ten (10) decorative chrysanthemum cultivars that were planted at the Kemper Center’s Lois Whiteside Franklin Flower Trial Garden in spring 2002 for purposes of evaluating garden mum performance in the St. Louis climate. MARILYN is sometimes sold as a cultivar of Dendranthema grandiflora or C. x morifolium, all of which are synonymous. U. S. Plant Patent #7905 issued July 7, 1992.
