Gloriosa Daisy Rudbeckia Hirta Flower Seeds, Black-Eyed Susan, Biennial, Beautiful! Height: 24-36".
Depth: DO NOT COVER but press into soil! SOIL temperature MUST be kept at 70F for proper germination!!! Cool soil, particularly at night can inhibit or significantly delay germination. Overly warm soils, well above 90F, can inhibit germination and provide ideal conditions for seed rot.
To keep soil temperature warm, start seeds indoors. Keep the container covered with a plastic bag on the top of the fridge where the room temperature is higher, therefore the soil temperature is good for germination.
Keep soil moderately moist, though not overly, dripping wet. Water soil when the soil surface just begins to dry. Allow proper air circulation for containers.
Once seedlings have sprouted, keep in small containers until a few sets of leaves have developed. Transplant to larger containers or outdoors.
A superb performer for the perennial flower border, Rudbeckia Gloriosa Daisy, is easily propagated from seeds, and it offers a rewarding long bloom season with a glorious display of color! Gloriosa Daisy blooms vary from solid gold, bicolors, and doubles. The Gloriosa Daisy plant, a relative of Black-eyed Susan, typically has larger blooms with brown centers and a mahogany red color shooting into yellow outer petals. This flower will grow in most soil types that are well-drained and in sunny settings. These biennials bloom the first year, so are often grown as annuals. Very easy to grow from seed. These attractive blooms grow on sturdy stems, and make long-lasting cut flowers. Will attract butterflies, and re-seed itself. *** HOW TO GROW: Depth: DO NOT COVER but press into soil! The Gloriosa plants form a clump that will reach 12 inches in width. Deadheading prolongs the bloom season, but Gloriosa Daisies will re-seed themselves readily if you leave a few blooms to go to seed. Rudbeckia Hirta flowers will not bloom much the first year the wildflower seeds are sown. Subsequent years will bring many more blooms. *** **SOIL Temperature for Germination: 70-85F **Plant Spacing: 12-18 inches. **Hardiness: Zones 3-10. **Sun Requirement: Full Sun / Partial Shade. **Days to Germination: 7-30 days. **Germination Rate: 94%.
