Globe Amaranth seeds were first planted by Thomas Jefferson at Shadwell, his boyhood home, on April 2, 1767. It was introduced into Europe from India in 1714 and was grown in Virginia by John Custis of Williamsburg as early as 1737. The clover-like flowers bloom from summer through fall in shades of magenta, pink, and occasionally white. Globe Amaranth thrives in hot, dry weather and the long-lasting flowers are superb for fresh or dried arrangements. Jefferson-documented: Globe Amaranth was documented by Thomas Jefferson in his Garden Book, Notes on the State of Virginia, or other writings.
Start Globe Amaranth seeds indoors 6-8 weeks before last frost at 70 degrees. Soak seeds in hot water for four hours to hasten germination. Transplant to cell-packs once they have several true leaves, then harden off and transplant outdoors after last frost. Approximately 35-50 seeds per packet.
