General Culture:

Easily grown in average, medium, well-drained soils in part shade to full shade. Prefers moist, rich, organic soils. Tolerates wet soils. Spreads by rhizomes to form an attractive ground cover, but is easily controlled. Remove spent flower stems for best ground cover appearance. Easily grown from seed and may self-seed in the garden.

Noteworthy Characteristics:

Goldenstar is a rhizomatous, low-growing perennial which typically forms a foliage mat 3-4" tall, but flowering stems can bring total plant height to 8-12". Features star-shaped, bright yellow flowers (to 1.5" diameter) on stems originating in the leaf axils. Each flower has five, rounded, slightly-notched, yellow petals and a center tuft of yellow disk flowers. Long, spring to fall bloom period in cool summer climates. In hot summer climates such as St. Louis, bloom is profuse in spring, but usually becomes sparse or stops in the heat of the summer, with a light rebloom occurring in the fall. Ovate, toothed, bright green leaves to 3" long. Native to rich woods in southeastern U.S.

Problems:

No serious insect or disease problems. Some susceptibility to mildew.

Uses:

Ground cover for woodland gardens, native plant gardens or naturalized areas. Edging for woodland paths. Also may be used in shaded areas of border fronts or rock gardens.
