What Is a Gloriosa Daisy?

Rudbeckia gloriosa is a hardy wildflower more commonly known as the Gloriosa Daisy and also know as Rudbeckia hirta. The daisy-like flower is a descendant of the Black-eyed Susan. The plant is grown in the U.S. Department of Agriculture plant hardiness zones 3 through 10.
  1. Plant Type

    • The daisy plants can be seeded into a flower bed as an annual or biennial. The seeds are compacted into the soil or planted at a depth of 1/16 to 1/8 inch deep in the spring of the first year. Seedlings can be started indoors and transplanted to a flower bed as an annual, biennial or perennial planting. The plants will germinate within 20 days and will mature to a blooming stage during the second spring of growth. The wildflower grows from an existing perennial root system each spring and flowers for most of the summer, on into September.

    Identifiers

    • The Gloriosa Daisy is recognizable with its bright golden orange-yellow 5- to 9-inch blossoms. A star burst of mahogany-red color flows out from a deep mahogany center over the petals. Some strains of the daisy plant have golden yellow petals with a dark mahogany center. The flowers bloom on stalks covered in elongated thin green leaves. The plant clump grows to a height of 2 to 3 feet.

    Growing Conditions

    • The perennial daisy plant requires a sunny location for healthy growth. It will live in many types of well-drained soils. The plant can survive when neglected because it requires very little care and it is tolerant of drought and heat conditions. It will grow along the roadside, in a landscaped flower bed or open field.

    Use

    • The colorful flowering plant is a worthy addition to any landscape. Cut mature blossoms and buds and immerse them in cold water for a long-lasting floral arrangement. Split the stems at the bottom to keep them hydrated. Gloriosa daisies will last for a week or two when arranged in a vase of clean water. The blooms are useful as cut flowers to sell at roadside stands in the summer time. The flowers do not have a medicinal quality nor are they edible.
