Summer brings clouds of yellow pom-poms which age to brown on this native member of the sunflower family. The round flower clusters sit atop rings of small, down-turned petals, held up on flat stems lined with lanceolate leaves. The flower stalks reach 3 to 5 ft. in height and can be cut down once blooming has finished. Plant in full sun to light shade. Rosilla grows naturally by creeks and seeps and enjoys regular moisture, but will tolerate some drier periods. Attracts a wide variety of insects including bees and butterflies. Goldfinches love the seed. Reseeds readily.
