Gold and Silver Chrysanthemum

Ajania pacifica (ah-JAHN-ee-ah pa-SIF-ik-ah)

Family: Asteraceae Non-native Herbaceous (1-3 ft)

Silver and gold chrysanthemum is a shrubby herbaceous flowering perennial in the aster family (Asteraceae). It is native to the island of Honshu, the main island of Japan, where it grows along the coast. It is also found in central and eastern Asia. The genus name (Ajania) refers to the Russian port city of Ayan, while the species name (pacifica) refers to the Pacific coastal cliffs of Japan where the plant originated. It is common names refer to its silver leaf margins and gold flowers. Silver and gold chrysanthemum thrives in full sun, but will tolerate partial shade. Some afternoon shade is beneficial in hot summer climates. Plants may appreciate winter protection in USDA Zone 5. It grows well in all types of soil as long as there is good drainage; it does poorly in soggy ground. It is not particular about pH, as it thrives in all types of soil acidity. This plant reaches its full height in 2 to 3 years. It spreads over time by underground rhizomes; in several years it can span 3 feet wide. Pinch back tall stems in June or July to maintain a dense, bushy growth and do not over-water. Propagation is easy with stem cuttings or by dividing the root ball in the spring. This plant is noted for its low, mounding habit and striking variegated foliage. Also of note are its small, button-like yellow flowers in late fall, when other plants have stopped producing flowers. It is considered deciduous, but in some areas, it remains semi-evergreen. This plant is superb as a ground cover or a foliage plant in a border. Diseases, Insects, and Other Plant Problems : No significant problems. Wet soils in winter can be fatal. The Clemson Cooperative Extension Home & Garden Information Center has a factshee t on common pests and diseases.
