Best Shade Tolerant Perennials for Your Garden in August

As we move into the heart of August, many gardens can start to look a little tired, especially those areas that don't get much direct sun. We often think of bright, sunny spots for vibrant blooms, but shade gardens deserve their own special attention. We've put together a list of some of our favorite shade tolerant perennials that will keep your garden looking good even when the sun isn't shining brightly. These plants are reliable and add texture and color to those dimmer corners.

Key Takeaways

• Hostas are a go-to for shade gardens, offering a wide range of leaf colors and textures.

• Astilbe brings feathery plumes of color to shady spots, blooming through the summer.

• Ferns provide beautiful, naturalistic foliage that adds a lush feel to any shaded area.

1. Hosta

When we think about shade-tolerant perennials, the Hosta immediately comes to mind for many of us. These plants are absolute workhorses in shady spots, offering a wide range of leaf colors, textures, and sizes that can really fill out a garden bed. We find that their versatility is unmatched; whether you're looking for a low-growing ground cover or a taller, statement plant, there's a Hosta for the job. Their foliage is the main attraction, with varieties ranging from deep blues and greens to vibrant yellows and variegated patterns. While they do produce flowers, often a lovely lavender or white spike, it's the leaves that truly make them shine throughout the growing season, especially in August when many other plants might be fading.

We've found that choosing the right Hosta depends on the specific conditions of your garden, but generally, they prefer moist, well-draining soil and protection from the harshest afternoon sun. Even in deep shade, many Hostas will perform well, though some of the more brightly colored varieties might appreciate a bit of morning sun to really pop.

Here are a few things we consider when selecting Hostas:

• Leaf Color: From deep blues like 'Blue Angel' to variegated types like 'Patriot', the color options are vast.

• Leaf Texture: Some have smooth, glossy leaves, while others are heavily textured with prominent veins or a puckered appearance.

• Size and Habit: Hostas range from miniature varieties that stay just a few inches tall to giants that can spread several feet wide.

• Sunlight Tolerance: While all are shade plants, some can handle more sun than others. Check the specific variety's needs.

We've learned that slugs and deer can be a challenge with Hostas, so it's worth considering preventative measures if these pests are common in your area. Sometimes, simply choosing a variety known to be more slug-resistant can make a big difference.

We also appreciate that Hostas are generally low-maintenance once established. A good layer of mulch helps retain moisture and suppress weeds, and dividing them every few years can help rejuvenate older plants and propagate more for other shady corners of our garden.

2. Astilbe

When we think about adding some color and texture to our shady spots, Astilbe often comes to mind. These plants are just fantastic for bringing a bit of life to those areas where the sun doesn't quite reach. We find their feathery plumes to be quite striking, especially when they start to bloom in the summer months. They really do add a different kind of beauty compared to your typical shade-loving plants.

Varieties and Bloom Times

There are so many different kinds of Astilbe, and they come in a surprising range of colors and sizes. You can find them in shades of pink, red, white, and even a soft lavender. The bloom times can also vary a bit, which is helpful if you want to extend the flowering season in your garden. Some start earlier in the summer, while others hold their blooms a bit longer.

• Early Summer Bloomers: Often smaller varieties, providing color in June.

• Mid-Summer Bloomers: The most common group, typically blooming in July.

• Late Summer Bloomers: These can carry the color into August and even September.

Growing Conditions

Astilbe really thrive in moist, well-drained soil. They don't like to dry out, so if you have a spot that tends to get parched, you might need to give them a little extra attention with watering. They prefer partial to full shade. Too much direct sun, especially in the afternoon, can scorch their leaves. We've found that amending the soil with compost before planting really helps them get established.

Care and Maintenance

Once they're planted, Astilbe aren't too demanding. We usually give them a good watering during dry spells. In the fall, after the foliage has died back, we often cut the flower stalks down. Some people leave them for winter interest, which can look nice with a bit of frost on them, but we prefer to tidy them up.

We've noticed that Astilbe can be quite susceptible to slug and snail damage, especially when the new shoots emerge in spring. Keeping an eye out for these pests and taking action early can save your plants from looking like they've been through a battle.

3. Coral Bells

Varieties and Characteristics

Coral Bells, or Heuchera, are a garden favorite for their stunning foliage. We find their leaf colors range from deep purples and burgundies to vibrant oranges, greens, and even silvery tones. The small, bell-shaped flowers, usually white or pink, appear on delicate stalks in late spring to early summer, but it's the leaves that truly steal the show. Some popular cultivars we've grown include 'Palace Purple' with its rich, dark leaves, and 'Caramel' which offers a lovely peachy-orange hue that brightens shady spots. Their size can vary, but most stay within a 1-2 foot spread.

Growing Conditions

These plants prefer partial to full shade. Too much direct sun, especially in the afternoon, can scorch their leaves. We aim for soil that drains well; they don't like sitting in wet conditions. A good layer of mulch helps keep their roots cool and moist. We usually plant them in spring or fall.

Care and Maintenance

Coral Bells are generally low-maintenance. We deadhead the flower stalks after blooming if we want to encourage more leaf growth, though leaving them can add a bit of winter interest. Dividing them every few years helps keep the plants vigorous. We've found that a light feeding in spring with a balanced fertilizer is usually enough. They are quite hardy once established.

Companion Planting

We often pair Coral Bells with other shade-loving plants. They look great alongside Hostas, Ferns, and Astilbes. Their varied leaf colors provide a wonderful contrast to the greens of many shade garden plants. We also like to plant them near the front of borders where their colorful foliage can be easily seen.

4. Bleeding Heart

When we think about shade-tolerant plants, Bleeding Hearts (Dicentra spectabilis) often come to mind, and for good reason. These charming perennials offer a unique, old-fashioned appeal with their distinctive heart-shaped flowers that dangle gracefully from arching stems. They truly bring a touch of romance to shady garden spots.

We find that Bleeding Hearts perform best in partial to full shade, especially in warmer climates where they can appreciate some protection from the harsh afternoon sun. They prefer moist, well-drained soil rich in organic matter. While they are generally low-maintenance, a good layer of mulch can help keep their roots cool and retain moisture, which they appreciate.

One thing to note is that Bleeding Hearts tend to go dormant in the heat of summer, especially after they finish blooming. This means their foliage might disappear for a while. Don't worry, this is perfectly normal! It's their way of conserving energy.

Here are a few things we've learned about caring for them:

• Planting Location: Aim for a spot that gets morning sun and afternoon shade, or dappled light throughout the day.

• Soil: Amend your soil with compost or other organic material before planting to give them a good start.

• Watering: Keep the soil consistently moist, but not waterlogged. They don't like to dry out.

• Support: While not always necessary, taller varieties might benefit from a little staking if they get top-heavy, especially when in full bloom.

Bleeding Hearts are wonderful for planting amongst ferns or hostas, creating a beautiful layered effect in a woodland garden setting. Their delicate blooms are a real treat in the spring and early summer.

5. Ferns

Ferns are a fantastic choice for adding texture and lushness to shady garden spots. We find they really bring a different kind of green to the landscape, often with delicate, feathery fronds that can soften the edges of paths or create a dense ground cover. They don't typically flower, but their foliage is so varied and interesting, it more than makes up for it. Many varieties thrive in the kind of dappled light that other plants might shy away from.

Ostrich Fern

Ostrich ferns are known for their tall, vase-shaped fronds that can reach up to five feet. They spread readily, so give them some space. We like to plant them near water features or in areas where we want a dramatic, natural look. They're quite hardy and can handle a bit more sun if the soil stays moist.

Lady Fern

Lady ferns are more delicate, with finely cut, airy fronds. They tend to be smaller than ostrich ferns, usually topping out around two to three feet. These are great for planting under larger shrubs or in mixed borders where their fine texture can contrast with bolder leaves. They prefer consistently moist, well-drained soil.

Japanese Painted Fern

For a bit of color, the Japanese painted fern is a real standout. Its fronds have a silvery sheen with hints of burgundy or red, especially on the new growth. It's not as tall as some other ferns, typically growing about 18 inches to 2 feet. This fern adds a touch of elegance and subtle color to the shade garden. It does best with partial to full shade and moist soil.

When choosing ferns, consider the mature size and their specific moisture needs. Most ferns appreciate rich, organic soil. We often amend our planting areas with compost to give them a good start. They generally don't need much in the way of fertilizer, but a light feeding in spring can be beneficial.

• Soil Preference: Most ferns prefer moist, humus-rich soil. Avoid heavy clay or overly sandy soils.

• Watering: Consistent moisture is key, especially during dry spells. They don't like to dry out completely.

• Light: Dappled shade to full shade is ideal for most varieties.

• Pest & Disease: Generally quite resistant, but watch out for slugs and snails which can damage the new fiddleheads.

6. Brunnera

When we think about adding some sparkle to our shady spots, Brunnera often comes to mind. These plants are really something special, especially for areas that don't get much direct sun. We've found that their heart-shaped leaves are quite attractive on their own, but it's the spring flowers that really steal the show. They look like tiny blue forget-me-nots, and they create a lovely carpet of color. We like to plant them near the front of a border or along a path where their delicate blooms can be easily seen. They also do well in containers, bringing that splash of blue to patios or decks.

Varieties to Consider

There are a few different types of Brunnera that we find particularly appealing. Each offers a slightly different look, so we can pick the one that best suits our garden's style.

• 'Jack Frost': This is probably the most popular variety, and for good reason. It has silvery leaves with green veining, making it a standout even when it's not in bloom. The blue flowers in spring are a bonus.

• 'Silver Heart': Similar to 'Jack Frost', this one also features striking silver foliage. The leaves are a bit more rounded, and the silver color is very bright.

• 'Looking Glass': Another excellent choice for silver foliage. The leaves are almost entirely silver, with just a hint of green near the edges. It really brightens up dark corners.

Growing Conditions

Getting Brunnera to thrive isn't too complicated, but we do pay attention to a few key things.

• Light: They prefer partial to full shade. Too much sun can scorch their leaves, especially in the afternoon. We aim for dappled shade or morning sun.

• Soil: Good drainage is important. We amend our soil with compost to give them a nutrient boost and help with moisture retention. They like soil that stays somewhat moist but not waterlogged.

• Water: Regular watering is needed, particularly when the plants are getting established and during dry spells. We try to water at the base of the plant to keep the foliage dry.

We've noticed that Brunnera really shines when planted in groups. The mass of blue flowers in spring is quite breathtaking, and the variegated foliage provides interest throughout the growing season. It's a plant that rewards us with very little fuss.

7. Lungwort

Lungwort, or Pulmonaria, is a delightful ground cover for shady spots. We appreciate its early spring blooms, which often appear in shades of pink, blue, and white, sometimes on the same plant. The foliage is also a major draw, with many varieties featuring attractive silver spotting that brightens up dim corners of the garden.

We find that Lungwort thrives in moist, well-drained soil and prefers partial to full shade. It's a low-maintenance plant once established, making it a favorite for many gardeners.

Here are some key points about growing Lungwort:

• Planting Time: We typically plant Lungwort in the spring or fall.

• Watering: Consistent moisture is important, especially during dry spells.

• Soil: It prefers humus-rich soil.

• Pest Resistance: Generally resistant to deer and rabbits.

We've noticed that Lungwort can sometimes be susceptible to powdery mildew, especially in crowded conditions or when air circulation is poor. Proper spacing and watering at the base of the plant, rather than overhead, can help prevent this issue.

8. Solomon's Seal

When we think about plants that do well in shady spots, Solomon's Seal often comes to mind. This plant is a real workhorse for us in the garden, especially when we need something reliable that won't demand too much attention. Its arching stems, dotted with those distinctive bell-shaped flowers in spring, give it a graceful look that really softens the landscape. Even after the flowers fade, the foliage remains attractive through the summer and into fall, often turning a lovely yellow before it dies back. We find it pairs wonderfully with ferns and hostas, creating a lush, layered effect.

Bloom Time

While the flowers are a spring feature, typically appearing in April and May, the plant's main appeal for an August garden is its foliage. It provides a consistent green presence when many other spring bloomers have finished their show.

Growing Conditions

Solomon's Seal prefers moist, well-drained soil and partial to full shade. It can tolerate a bit more sun if the soil stays consistently damp, but we generally plant ours where they get dappled light or morning sun only. It's not overly fussy about soil type, but adding some compost when planting really helps it get established.

Varieties to Consider

There are several types we like to use:

• Polygonatum odoratum 'Variegatum': This is a popular choice with white-edged leaves, which adds a bit of brightness to shady corners.

• Polygonatum biflorum: The native species, often a bit more upright in habit.

• Polygonatum humile: A smaller, more compact variety that's great for the front of a border.

Maintenance

Once established, Solomon's Seal is quite low-maintenance. We usually just cut back the dead foliage in late fall or early spring. It doesn't typically suffer from many pests or diseases, which is another reason we appreciate it. Division is rarely needed, but if you do divide it, spring is the best time to do so, just as new shoots are emerging.

9. Foamflower

When we think about adding delicate beauty to our shady garden spots, Foamflower, or Tiarella cordifolia, often comes to mind. These low-growing plants are fantastic for ground cover and look especially good along the edges of woodland gardens or nestled amongst ferns. Their leaves are often attractively lobed, and in the spring, they send up airy spikes of frothy, white flowers that really do resemble foam. They aren't the showiest plant in the garden, but their subtle charm is undeniable.

We find that Foamflower prefers consistently moist, well-drained soil rich in organic matter. They can tolerate a range of light conditions, from full shade to partial shade, but we've noticed they do best with a bit of morning sun and afternoon shade, especially in warmer climates. Too much direct sun can scorch their leaves.

Here are a few things we appreciate about Foamflower:

• Attractive Foliage: Many varieties have leaves that are marked with deep red or brown, adding interest even when the plant isn't in bloom.

• Spring Blooms: The delicate, star-shaped flowers appear in late spring to early summer, providing a soft texture.

• Low Maintenance: Once established, they are quite easy to care for, requiring little more than consistent moisture.

• Spreading Habit: They spread gently by runners, making them excellent for filling in spaces and preventing weeds.

We've found that planting them in groups really makes a statement. They naturalize well, so don't be surprised if they spread a bit over time, creating a lovely carpet of green and white.

We've had success planting Foamflower in areas where other ground covers struggle. Their ability to thrive in shady, moist conditions makes them a reliable choice for those trickier spots in the garden. Just make sure the soil drains well, and they'll reward you with their understated beauty year after year.

10. Heuchera

We often find ourselves drawn to the vibrant colors and interesting leaf shapes of Heuchera, also commonly known as Coral Bells. These perennials are fantastic for adding texture and color to shady spots in our gardens, especially when the summer sun starts to fade. Their foliage provides interest from spring through fall, often persisting through milder winters. We appreciate their adaptability; while they prefer dappled shade, many varieties can tolerate more sun if kept consistently moist. When choosing Heuchera, consider the mature size and color palette to best suit your garden design.

Varieties to Consider

We've had good luck with several types:

• 'Palace Purple': Known for its deep, reddish-purple leaves.

• 'Caramel': Offers lovely caramel-colored foliage that can shift with the seasons.

• 'Black Beauty': A striking dark foliage option that really makes other plants pop.

• 'Green Spice': Features silvery-green leaves with a delicate veining.

Care Tips

Caring for Heuchera is generally straightforward. We find that:

1. Soil: They do best in well-draining soil. We often amend heavier clay soils with compost to improve drainage.

2. Watering: Consistent moisture is key, particularly during dry spells. We try to water at the base of the plant to keep the foliage dry.

3. Mulching: A layer of mulch helps retain soil moisture and keeps the roots cool.

4. Division: Over time, clumps can become woody. We divide them every few years in early spring to rejuvenate the plant.

Bloom Time

While we grow Heuchera primarily for its foliage, we also enjoy the delicate, bell-shaped flowers that appear on slender stalks in late spring to early summer. These blooms attract pollinators, which is always a bonus in our garden. The flower color can vary from white to pink to red, depending on the cultivar. We often deadhead spent flower stalks to keep the plant looking tidy and encourage more leaf growth.
