Thomas Jefferson forwarded seeds of this vigorous vine to his two daughters, Mary and Martha, in 1791 from Philadelphia. The seeds of this morning glory relative were planted "in boxes in the window" at Monticello. Cypress Vine is a self-seeding annual with star-shaped scarlet flowers and ferny foliage that attracts hummingbirds and butterflies. Jefferson-documented: Cypress Vine was documented by Thomas Jefferson in his Garden Book, Notes on the State of Virginia, or other writings.
Start Cypress Vine seeds indoors 6-8 weeks before the last spring frost at 70 degrees F. Before sowing, scarify and pre-soak seeds for 24 hours. Transplant to individual pots, then harden off and plant outdoors after the last frost. Seeds can also be sown directly after the last frost. Provide cypress vine a support structure. Approximately 10-15 seeds per packet.
