It's probably to late to plant spring blooming bulbs and perennials. Don't worry. We've potted up a bunch of new bulbs and plants for spring.Although most are dormant for the winter, the primulas and hellebore are available now for you to enjoy their early blooms.
Dog tooth violets (Erythronium dens canis "Pagoda") are not actually violets. They have a bulb that is white and pointed like a dog's tooth. They are easy to grow in woodland conditions (afternoon shade and regular moisture) and are as reliably perennial as daffodils. Dog tooth violets have showy, pendulous, star-like yellow flowers for a long period in early spring. Their broad, waxy leaves are often mottled with pale maroon markings. We containerize them in fall, so they are ready to bloom in spring.
