Hibiscus are showy shrubs with large blooms that like full sun, good drainage and regular water. Some are tropical need protection from frost, others such as the Rose of Sharon (Hibiscus syriacus) will survive in cold climates. All are susceptible to aphid and white fly so rinsing the foliage with a strong jet of water from the hose can help keep these pests away. Keep growing, Marianne Binetti
