Container Gardens Made for the Shade

Nearly every gardener has experienced the problem of too much shade, which can cause plants to become too leggy or fail to thrive. Whether it's a wooded suburban lot or a north-facing apartment balcony, low light means more growing challenges. Rather than being problematic, these dark areas can be viewed as an opportunity.

Pots in shaded entryway
Pots in this shaded entry garden are grouped together for greater impact. Phyllostachys nigra (black bamboo), offers structure and height. Other plants include ‘Kong’, ‘Sedona’ and ‘Chocolate Mint’ coleus, ‘Mardi Gras’ and ‘Margarita’ sweet potato vines, and ‘Bonfire’ begonia. Photo: Janet Loughrey. Designer: JJ De Sousa.

Adding containers to shady spots is a practical way to optimize these spaces. By using brightly colored or shiny metal pots, combined with lighter or contrasting hues of foliage and flowers, these decorative arrangements can brighten up even the darkest corner of a porch, deck, or entryway.

A stump is cleverly recycled as the base for a shallow log container that blends perfectly with the landscape. The emphasis is on woodland foliage, with hart’s tongue and deer ferns, moss, and native sedums. A small hellebore and hosta ‘Tiny Mice’ complete this serene combination. Photo: Janet Loughrey.

Choosing the right plants is essential to successful shade gardening. Woodland natives, ferns, and hostas are just a few plants that prefer lower light levels. Many garden specimens will thrive equally well in containers, given the right conditions. A single plant, such as Japanese maple or bamboo, can be just as compelling as a combination.

For shade containers, Vina Winters chooses a foliage specimen such as Hypoestes (polka dot plant) and pairs it with a similarly-hued flower such as tuberous begonia. Soft shield and maidenhair ferns provide contrasting texture and shape. Photo: Janet Loughrey. Designer: Vina Winters.

Plants with attractive foliage offer reliable season-long color. Coleus are workhorses of the shade garden, with a nearly endless array of colors. Other reliable foliage standbys include Japanese painted fern, sweet potato vine, and Rex begonias.

An underutilized alternative to annual bedding impatiens is Torenia (wishbone flower), which blooms consistently over several months in colors of blue, purple, pink, and yellow. Other prolific bloomers include fuchsias and begonias such as ‘Bonfire’.

Optimal growing conditions are essential to healthy shade container plantings. Landscape designer Lucy Hardiman uses high-quality potting soil, replenishing it annually. She mixes a time-release fertilizer into the top several inches of soil before planting. Because containers need frequent watering during hot summer months, nutrients quickly leach out of the soil. In midsummer, Hardiman supplements with a water-soluble bloom booster fertilizer every other week.

There are no hard and fast rules to mixing and matching plants for shade containers. Breaking the rules can result in some unexpectedly delightful surprises.
