Shade Garden Plants for Iowa Landscapes

Shade can feel like a limitation when you are planning your landscape, but it does not have to be. Some of the most beautiful gardens in the Cedar Valley are in shady yards where sun-loving plants would struggle. The key is picking plants that actually prefer shade and giving them the conditions they need. A lot of homeowners fight against shade, trying to force grass to grow under a mature maple or planting sun-loving perennials in a north-facing bed. That is a losing battle. Work with the shade instead of against it, and you will end up with a garden that looks lush and intentional rather than thin and struggling.

Hostas are the undisputed kings of the shade garden, and for good reason. They come in hundreds of varieties that range from tiny miniatures under 6 inches tall to massive specimens that spread 4 feet wide. Leaf colors cover the full spectrum from chartreuse to deep blue-green to variegated combinations of white, cream, and gold. The bigger the leaves, the more impact a single hosta has in the garden. They are incredibly low maintenance. You plant them, water them during dry spells the first year, and they come back bigger every season. In Iowa, hostas handle our winters with no trouble at all. The foliage dies back after the first hard freeze, and you cut it off in spring before the new shoots emerge. That is about all the work they need.

Ferns bring a texture to shady gardens that nothing else can match. The delicate, feathery fronds soften the bold leaves of hostas and create contrast that makes both plants look better. Ostrich fern is a native Iowa fern that spreads nicely and fills in large areas. It gets 3 to 4 feet tall in good conditions and adds a woodland feel to the garden. Lady fern is smaller and more delicate, perfect for the front of a shaded bed. Japanese painted fern has silver and burgundy tones that make it a standout even from a distance. All of these ferns need consistent moisture, especially during dry spells. In the shade under a tree canopy where the roots compete for water, that means watering during dry weeks in July and August.

Heuchera, commonly called coral bells, gives you foliage color that holds all season in part to full shade. The leaves come in shades of deep purple, bronze, bright lime, and silver with dark veins. Unlike a lot of shade plants that are all about the leaves, heuchera also sends up delicate flower spikes in late spring and early summer. The tiny bell-shaped flowers on tall stems add a vertical element to the front of the shade border. Heuchera is a heavy feeder, so give it rich soil with plenty of organic matter mixed in. Plant it where it gets some morning sun if possible, which brings out the brightest leaf colors. But it will do fine in full shade too.

Do not forget about ground covers for the shade. Creeping phlox, lamium, and vinca minor all spread to fill bare areas under trees and between larger plants. Creeping phlox blooms with masses of pink, purple, or white flowers in spring and stays green through summer. Lamium has silver and green variegated leaves with small pink or white flowers that appear in waves from spring through fall. Vinca minor, or periwinkle, has glossy evergreen leaves that stay green all winter and blue flowers in spring. These ground covers solve the problem of bare soil under trees where grass refuses to grow. They look better than mulch, and once established, they need almost no care.

We design and plant shade gardens for homeowners across Cedar Falls and the Cedar Valley. The shade in your yard comes from different sources in different neighborhoods. Mature trees in older parts of town create deep, dry shade where roots compete for every drop of water. Newer developments might have shade from buildings or fences that creates different conditions. We look at what you are working with and recommend plants that will thrive in your specific situation, not just a generic list. If you have a shady spot that you have not known what to do with, give us a call. It might become your favorite part of the garden.
