Fragrant, double, soft yellow flowers point upright above the large green leaves on this non-hardy shrub that thrives and flowers during the warmer weather of early summer through the first hard frost of fall. When grown outdoors either in a large container or in the ground, it rarely suffers from aphids or spider mites. However, greenhouse- grown plants are susceptible to these pests and will need to be grown in full sun and the foliage rinsed off several times a week to prevent infestations from getting to the point where pesticides are required. The flowers are delightfully fragrant, particularly in the evenings, when the combination of light-colored flowers and fragrance are an attractant for a number of moths; during the daytime hummingbirds and butterflies are the primary visitors.
