About Yellow Gaillardia: Meriwether Lewis collected the first specimen of this wildflower on July 7, 1806. His research of this and other native species was completed by botanist Frederick Traugott Pursch in 1813, who completed a catalogue of the species discovered on the famous expedition. The genus name Gaillardia honors an 18th century French botanist named Gaillard de Charentonneau, while the species name "aristata" means "bristle" in reference to both the hairy leaves and the spikes on the seeds.
Yellow Gaillardia Germination: Direct sow in late spring, planting ¼” below the surface of the soil and compacting it slightly. Keep the soil evenly moist and at a temperature of 70-75 degrees F until germination, which widely varies from 20-70 days. Since these plants do not transplant well, they should be planted in peat pots if started indoors.
Growing Yellow Gaillardia Seeds: Water the seedlings until they become established. Mature plants tolerate drought well, though watering in especially dry periods will improve the blooming. Excess moisture may result in root rot and other disease. Deadheading or cutting back the plant will also increase the blooms. This is a rather short-lived perennial that does not readily self-sow. This plant attracts butterflies and resists deer.
Harvesting Yellow Gaillardia: For fresh flowers, cut long stems of flowers that have just opened and place them in water immediately; strip the leaves that will fall below the water.
Saving Yellow Gaillardia Seeds: After the petals of the flowers drop off, the center will begin to turn from green to brown. Cut the seed heads off when they have ripened but before they begin to shatter. Spread them out to dry in a protected location for 2-3 weeks. Crush the seed heads to separate the seed from the stems. Store the cleaned seed in a cool, dry place.
