Evergreen perennials for the Midwest garden

The grasslike 'Evergold' sedge is evergreen, too. It was left in this container to add another color and texture to a winter arrangement, it's third season in a pot. (C) Jo Ellen Meyers Sharp

Say evergreens and most people think pine, spruce or arborvitae. But several perennials fall into this category, including a couple of grass-like plants.

Sedge

Sure, sedge (Carex spp.) can be a weed, but there’s a whole bunch of these grasses that have been cultivated and made garden worthy. Some are native, too. Not only are many sedges evergreen, they are tolerant of dry, wet, sun and shade.

Probably the most readily available is ‘Ice Dance’ (C. morrowii). The narrow green and white blades perk up containers or perform like a pro as an edging on a garden bed. Sedges also can serve as a ground cover.

A great place to see a large planting of a native sedge is outside the Deer-Zink Pavilion at the Indianapolis Museum of Art. A large bed is planted with Pennsylvania sedge (C. pensylvanica), a shade tolerant beauty that looks great all year.

Sedges bloom, but their flowers, although attractive, are not particularly showy. I don’t cut them off. There are several yellow or gold cultivars, too, including ‘Evergold’ (C. oshimensis). Most sedges range 8 to 15 inch tall.

Lilyturf

Along the same ideas as sedge is lilyturf (Liriope spp.), another grass-like ground cover that gets about 12 inches tall. It, too, tolerates sun or shade, but its spike of blue flowers is showy in late summer, followed by black berries.

There are two types of lilyturf, one that spread by underground rhizomes (L. spicata) and one that is a clump grower (L. muscari). To help hold soil on a hillside or to cover a challenging areas, the spreading one would be ideal. The clump grower, a popular one is ‘Big Blue’, works well in many applications, including as a year-round container plant.

Coral bells

I can’t say enough good about coral bells (Heuchera spp.) because the come in so many leaf colors and forms. Found only in North America, coral bells are prized as much for their foliage as they are the blooms.

In fact, as breeders worked on this plant, the foliage got all the attention to the detriment of the flowers. But new introductions, such as ‘Berry Timeless’, have an improved floral show.

Coral bell foliage may change color as it moves through the season, but even in winter, there’s a presence in the landscape, even under snow. Coral bells are very shade tolerant, but prefer well-drained soil.
