Site Selection


Gloriosa daisy is an annual that prefers full sun to partial shade. Plants will tolerate poor soils that are well-drained and once established, thrive in dry conditions.




Direct sow outdoors once the danger of frost has passed. Seed can also be started indoors 6-8 weeks before the last frost and transplanted outdoors once the danger of frost has passed. Optimal soil temperatures for germination are 70-75°F. Seeds require light for germination. Sow seeds no more than 1/8" deep and 4-6" apart. Seeds will germinate in 10-30 days. Thin seedlings so mature plants are 12-24" apart.




Gloriosa daisy flowers from summer to fall. Harvest cut flowers anytime during this flowering period.
