Heuchera Dark Leaves: A Guide to Growing and Caring for Heucheras with Dark Foliage

Table of Contents

Heuchera plants, also known as coral bells, are perennials that are loved by gardeners and landscapers alike for their colorful and showy foliage. While there are many varieties of heuchera plants available, those with dark leaves are particularly highly sought after due to their striking appearance.

In this guide, we'll explore everything you need to know about growing and caring for heuchera plants with dark foliage, from planting and watering to pruning and propagating. We'll also take a look at some companion plants that pair well with heuchera dark leaves, as well as frequently asked questions about these beautiful perennials.

What are Heuchera plants?

Heuchera plants are native to North America and belong to the Saxifragaceae family. They are commonly grown for their attractive foliage and delicate bell-shaped flowers that bloom on tall spikes in early summer.

Heuchera plants are herbaceous perennials, which means that they die back to the ground each year and then grow again the following spring. There are over 50 species of heuchera, with many more cultivars available to gardeners.

Why choose Heucheras with dark leaves?

While all heuchera plants have lovely foliage, those with dark leaves make a particularly bold statement in the garden. The deep hues of black, burgundy, and purple create a dramatic contrast when paired with other plants, and they add depth and richness to mixed borders, beds, and containers.

In addition to their beauty, heuchera plants with dark leaves are generally low-maintenance and hardy enough to withstand most conditions. They're relatively pest-free, and the leaves of most cultivars are semi-evergreen, meaning that they keep their color longer than many other plants.

Growing and Caring for Heuchera Dark Leaves

Planting Heuchera

Heucheras with dark leaves prefer well-drained soil in a location that receives partial shade to full sun. Although they can tolerate some drought once established, they will do best when watered regularly and deeply.

When planting heuchera, dig a hole slightly larger than the size of the container, and mix in some compost or other organic matter to improve the soil. Place the root ball into the hole, and backfill with soil, then water thoroughly. Mulching around the base of the plant will help retain moisture and suppress weeds.

Watering and Fertilizing Heuchera

Heuchera plants require regular watering, especially during periods of drought. While they can tolerate periods of dryness, consistent moisture will help them grow stronger roots and produce more abundant foliage.

Fertilizing heuchera with a balanced fertilizer (such as a 10-10-10 blend) every four to six weeks can help promote healthy growth and flower production. Be sure to follow the instructions on the fertilizer package for best results.

Pruning and Deadheading Heuchera

Pruning heuchera is generally not necessary unless you notice dead or damaged foliage. In this case, simply trim off the affected stems with a pair of clean shears. You can also remove spent flowers by cutting them back to the base of the spike, which will encourage new blooms to form.

Dealing with Pests and Diseases on Heuchera

Heuchera plants are relatively pest-free, but they can occasionally fall victim to aphids, mites, or snails. You can control these pests by spraying the leaves with insecticidal soap or a neem oil-based spray.

In terms of diseases, heuchera plants can be susceptible to root rot during periods of wet weather or if planted in heavy clay soils. To avoid this, make sure your heucheras are planted in well-draining soil, and avoid overwatering them.

Heuchera Varieties with Dark Foliage

Here are some popular cultivars of heuchera plants with dark leaves:

Heuchera 'Obsidian'

With its deep, glossy black foliage, 'Obsidian' is one of the most dramatic heuchera cultivars out there. The leaves have a slight shimmer that catches the light beautifully, making for a stunning display in any garden.

Heuchera 'Black Taffeta'

'Black Taffeta' has velvety, dark purple-black leaves with ruffled edges that mimic the texture of taffeta fabric. This cultivar looks particularly striking when paired with other bright colors, such as orange or yellow.

Heuchera 'Midnight Rose'

'Midnight Rose' is a unique cultivar with deep purple leaves speckled with bright pink dots. As the plant matures, the dots become more pronounced and cover more of the leaf surface, making for a lively and eye-catching display.

Heuchera 'Canyon Duet'

'Canyon Duet' is a newer cultivar with leaves that are a rich burgundy-red on top and deep mahogany below. This contrast creates a stunning effect when the plant is in full sun, and the color remains vibrant even in partial shade.

Propagating Heuchera with Dark Leaves

You can propagate heuchera plants with dark foliage in two ways: division or seed. Here's how to do each method:

Division Propagation

To propagate heuchera through division, wait until mid-spring when new growth starts to emerge from the ground. Using a sharp shovel, carefully dig up the clump of heuchera you want to divide, being sure to keep the root system intact. Then, use your hands or a knife to separate the clump into smaller sections, each with its own roots and shoots.

Replant the younger divisions in well-draining soil, keeping them consistently moist until they become established.

Seed Propagation

To propagate heuchera through seed, collect the seeds after the flowers have faded and the spikes have turned brown. Store the seeds in a cool, dry location until ready to use.

To start the seeds, sow them in moist potting soil and cover lightly with a layer of vermiculite or perlite. Keep the soil consistently moist and warm (around 70-75 degrees Fahrenheit), either by placing it in a bright location or using a heating mat.

When the seedlings have grown two or three sets of true leaves, transplant them into individual containers or into the garden bed.

Companion Plants for Heuchera Dark Leaves

If you're considering adding heuchera with dark foliage to your garden or landscaping project, here are some companion plants that pair well with them:

Astilbe

Astilbes are known for their feathery plumes of flowers in shades of pink, white, and red. They make a lovely contrast to heucheras with dark leaves, especially if planted in groups or drifts.

Ferns

Ferns come in many varieties, but those with lacy, delicate fronds are particularly beautiful when paired with heuchera. They add texture and movement to the garden, and their soft greens and silvers make a nice complement to dark-leaved heucheras.

Lamium

Lamium, or dead nettle, is a shade-loving groundcover that comes in many colors and patterns. The silver-green leaves of some varieties look great next to heucheras with dark foliage, and their small, tubular flowers provide additional visual interest.

Hostas

Hostas are a classic shade-loving perennial that pairs well with heucheras with dark leaves. Their large, bold foliage adds structure and mass to the garden, and they come in a variety of colors and shapes to suit any taste.

Heuchera plants with dark leaves are a beautiful addition to any garden or landscaping project. With proper care and attention, they can thrive and add unique interest to your outdoor space. Whether you choose one of the cultivars we've mentioned here or another variety that catches your eye, we're sure you'll love the drama and beauty that these perennials bring.
