YellowGloriosa Daisy Growing and Maintenance Tips
A biennial, it is a very prolific seeder and flowers from the first-year's germination. Grows best in an average to dry, well-drained soil, in full sun to partial shade. Deadheading will help with overall appearance but not necessary for extending bloom times. Tolerates hot and humid summers and has a good tolerance to drought. Leaving finished flowers will provide both winter interest and food for birds.
