This is the easiest primrose to grow, either from seed or purchased plants. The rugose foliage stays neat and compact and the brightly-colored flowers are conspicuous sitting atop the leaves. The plants stay low, reaching a height of about 6 inches, and they bloom in my bog garden for 8 to 10 weeks beginning in early spring. They increase rapidly and can be dug up and divided in their 3rd year from seed.
