The Daisy Gloriosa Blend, 'Rudbeckia hirta 'Gloriosa', has huge 4 to 7 inch flowers. The Gloriosa Blend loves the heat and is drought tolerant. Grown as an annual, Gloriosa Daisy is technically a short-lived perennial and may come back for a second or third year. The large, wide yellow flowers have brown bands or stripes with a brown center. This Daisy blooms for 8 weeks beginning in mid summer.
The Gloriosa will grow in almost any soil but it has a preference for rich, alkaline soils that are well drained. They are drought tolerant, but they will bloom best in moist soil. Plant in early spring, 3 to 4 weeks before the last average frost date, or plant up to 2 months before the first fall frost. The Gloriosa Blend is excellent for wildflower planting and in beds and borders. They maintain their color after other flowers are beginning to fade in the fall.
