Johnny-jump-up, or Heartsease, is a showy, self-seeding annual with small pansy-like flowers, each of them showing three colors: deep purple, yellow, and white. The plant was established in American gardens before 1700, and Thomas Jefferson sowed it at Shadwell on April 1, 1767, calling it "Tricolor". Jefferson-documented: This plant was documented by Thomas Jefferson in his Garden Book, Notes on the State of Virginia, or other writings.
Start Johnny Jump Up seeds indoors 8-12 weeks before the last spring frost. Transplant to cell-packs once they have several true leaves, then harden off and transplant outdoors 4-6 weeks before last frost. Johnny jump up plants grow in all but the hottest and coldest months of the year, and tolerate light frost. Approximately 90 seeds per packet.
