Nora Barlow Columbine, a modern name honoring Charles Darwin's granddaughter, is in fact an old, unusual type of double-flowered, short-spurred columbine known as far back as the 16th century. This short-lived but self-seeding perennial with rose-pink, green-tinged flowers will thrive in fertile, cool soils.
Sow seeds indoors 8-12 weeks before last frost date at 70 degrees F. To improve germination, pretreat seeds with cold, moist stratification for 3 weeks before sowing. Transplant to 3” pots once they have several true leaves, then harden off and transplant outdoors after last frost. Approximately 25-30 seeds per packet.
