Why September Is The Best Time To Plant This Ground-Covering Perennial With Gorgeous Blooms

September is the best time to put on those gardening gloves and give your favorite plants, including barrenwort (Epimedium spp.), a strong start to the season. As a perennial, it benefits from warm soil. By the time the frost comes around, the roots are already stable enough to stand up to the winter. And come spring, this easy-to-grow ground cover plant will brighten your garden.

Barrenwort, also known as bishop's hat, is a genus of herbaceous perennials in the barberry family. While most of its 58 species are native to Asia, specifically China, a few are evergreen varieties from the Mediterranean region. Cultivated and hybridized for over a century and a half, it can survive in many conditions. This hardy perennial is a force to be reckoned with, as its roots spread through rhizomes that can compete easily with nearby tree roots for nutrients. Its presence shoos off unwelcome wildlife like rabbits and deer, making it a great option for woodland areas, patios, walkways, shade borders, or even outdoor containers.

Give barrenwort shade, and it will reward you with four-pointed blooms in shades of red, pink, yellow, and white, along with glossy, heart-shaped (or arrow-shaped), semi-evergreen foliage that sets it apart from its fellow perennials. Another plus: Its leaves are edible. But if you're not into the bitter taste, soaking and boiling takes care of it. If you're looking for a ground cover perennial that loves shade, you've found it.

Before you get your hands dirty, make sure you have the right spot to plant your perennial. In cooler northern climates, it can handle more sun, but in most regions, you'll want your planting area to have at least partial or full shade. Barrenwort thrives in USDA hardiness zones 5 through 8, so keep that in mind. As for soil, it prefers fertile, well-drained ground that's acidic or neutral. Because of its ability to spread, plant crowns at least 18 inches apart so they have enough room to fully develop without crowding.

Water your young plant regularly to help strengthen its roots. Once it's established, it will do just fine in dry conditions. Though it's not demanding, feed it with leaf mold each year. Only prune if you are growing an evergreen variety. Divide your barrenwort every 3 to 4 years to ensure it stays strong. Spring or late summer is the perfect time to do it. While this plant generally isn't bothered by pests, do keep an eye out for occasional slugs and aphids. With a September start and minimal maintenance after it's firmly established, this drought-tolerant ground cover can grow in your yard and garden.
