Hibiscus rosa-sinensis

Hibiscus rosa-sinensis "Cooperi" is a great hibiscus to grow. Its white, pink and green foliage make it a wonderful plant in any collection. Unlike other hibiscus, "Cooperi" has a very compact habit. Ours is 3 feet tall at 5 years old.

Blooming Time: Summer. The red flowers appear at the tips of side branches and are up to 4 inches across.

Culture: Hibiscus rosa-sinensis "Cooperi" plants need a well-drained compost consisting of 2 parts peat moss to 2 parts loam to 1 part sand. The plants need full sun to partial shade with intermediate to warm temperatures. Water the plants freely during the growing season. Fertilize the plants twice monthly with a balanced fertilizer from April through September. To keep mature plants growing vigorously, prune out about 1/3 of the old wood in the spring. Pinching out tips of stems in spring and summer increases flower production. They may be grown outside in zone 7, but should be treated as annuals.

Propagation: Hibiscus rosa-sinensis "Cooperi" are propagated by cuttings or layers in spring.

Hibiscus rosa-sinensis "Cooperi" was featured as Plant of the Week December 1-7, 2000.
