Jefferson sowed seeds of this tender annual along his Roundabout flower border in 1811, calling it "Scarlet Mallow." He likely received seed from Philadelphia nurseryman Bernard McMahon, who noted it in his American Gardener's Calendar in 1806. This handsome plant of the Old World Tropics, rarely cultivated in America, has brownish-green stems and scarlet, mallow-like blossoms that open at noon and close at dawn. Direct sow or transplant to a sunny location after the last frost. Grows to five feet.
Approximately 20 seeds per pack.
