Culture
Easily grown in average, dry, well-drained soil in full sun. Tolerates light shade in hot climates. New growth may be cut back slightly in spring to maintain plant compactness and encourage bushy form. Remove spent flower heads to promote additional bloom. Divide clumps every 2-3 years to maintain vigor.
Noteworthy Characteristics
Nipponanthemum nipponicum, commonly called Nippon daisy, is a shrubby perennial which grows 1.5-3' tall. Features 2-3" diameter flower heads with white rays and green center disks. Flowers appear in fall on long stalks. Thick, oblong, coarsely-toothed, glossy, dark green leaves (to 3.5" long). Excellent and long-lasting fresh cut flower. Formerly known as Chrysanthemum nipponicum.
Genus name combines a name for Japan (Nippon) with chrysanthemum.
Specific epithet means of Japan.
Problems
No serious insect or disease problems. Leaf spots, stem rots and leaf miners are infrequent problems.
Uses
Nippon daisies tend to lose their lower leaves, and therefore generally put on their best display with smaller perennials planted in front to cover up their leafless lower stems. Excellent for mid-borders as long as dry soil requirements can be met.
