Echinacea companion plants are the final touch to a wildflower garden, sometimes they are called purple coneflower.

Echinacea Companion Plants

They are the perfect match for the wild coneflower, and they present a beautiful sight together, as is a plant that grows the healthiest under the full sun but can also thrive in partial shade and moist, well-drained soil.

With echinacea in the garden and a little bit of companion planting, you can easily fill your garden with vivid colors and a lush vibrance, making for a wondrous sight!

Keep reading the list of Echinacea purpurea companions, all of which also prefer the same conditions if they are to survive together. 

List of Echinacea Companion Plants

1. Stachys

Stachys is also known as the Hummelo betony, scientifically, and it is a beautiful perennial flowering plant. 

– Characteristics

It has dark green leaves and rosy-lavender flower buds that grow on the stems. These plants are easy to grow and maintain, and the beauty they bring with them is a good bonus. Stachys are related to the mint family and can grow up to two feet. 

– Aesthetic Features

The plant has upright flowering stems that can rise to about 12 inches above the foliage. These stems grow in late spring to early summer, and each limb has reddish-purple tubular flowers. The clumps of foliage spread over time to form a ground cover. 

Stachys Aesthetic Features

However, some varieties of stachys have gray fleshy leaves, but they are primarily grown for vivid flowers. These flowers provide a spectacular display, especially when there is a large cluster of them together.

– Pairing Benefits

Like echinacea, Stachys can also easily thrive under the full sun or in partial shade and grow excellently in hardiness zones 4 to 8, as compared to 3 to 9 for perennials. As such, you can grow them almost anywhere you can grow purple coneflowers, as they are the perfect companion. 

– Attracting Pollinators

These plants are a great source of attraction for many insects and birds. Stachys attract hummingbirds, bees, and butterflies. This interaction with many animals results in an increased pollination rate. Overall, being a companion of echinacea, they help increase the pollination rate for the coneflowers.

In addition to all these benefits, these flowers are very deer resistant. Plant coneflowers with them, and they will protect them from any unwanted ravagers.

2. Catmint

Catmint (Nepeta mussinii) is another gorgeous plant that can be a fantastic companion to echinacea. It is a perennial with lush green leaves and long stems.

– Aesthetic Features

Catmints bloom with incredible blue-lavender flowers along the stems. The vibrant beauty of the flowers accompanies the striking colors of echinacea perfectly, making it an excellent choice for a companion. It can grow up to 10 inches tall, with a usual spread of about 12 inches, though you can find taller or dwarf cultivars, due to their varieties. 

Catmint Safety Precaution

– Pairing Benefits

The most significant benefit of catmint as a companion plant is its natural bug-repelling ability. It is particularly effective against aphids, mosquitoes, and squash bugs. Catmint gets this ability from its secreted chemicals in the air, which triggers the chemical receptors that bring forth a sensation of pain or itch.

– Characteristics

Additionally, catmint is easy to grow and maintain and is drought-resistant. Like the coneflower seeds, catmint seeds also prefer the sun and moist, well-drained soil. Furthermore, catmint provides a few health benefits. The herbal tea from its roots helps treat numerous digestive and respiratory problems.

– Safety Precaution

Cat mint can cause cats to experience hallucinations. Be careful if you have one as a pet, because if they ingest it accidentally, it can cause harm as they are toxic to pets.

3. Black-Eyed Susan

The Black-eyed Susan is scientifically known as the Rudbeckia fulgida. This plant is a tall flowering plant that can grow up to three feet tall, and they combine very well with echinacea as its companion plant. 

– Aesthetic Features

The Black-eyed Susan produces yellow-orange daisy-like flowers. It is called “black-eyed” because of the dark brown center of its flower head. The yellow blooms contrast sharply with the purple coneflowers, enhancing the scene’s overall beauty. In addition, the different colors make the scenery more vibrant.

Black-Eyed Susan Benefits

– Pairing Benefits

This plant thrives under the full sun. It can also live under the partial sun, but its bloom would not be to its full potential. In addition to partial shade, this plant can also tolerate harsh conditions such as bad soil and water. But naturally, the flowers will not be able to bloom with their full brilliance, because they don’t receive proper nutrients.

The rigid stems provide structural support for the echinacea. In addition, the flowers attract insects, birds, and other pollinators. Like with Stachys, accelerated pollination helps grow the number of echinacea.

4. Coral Bells

Coral Bells have many other common names, such as Alumroot, American Sanicle, and Rock Geranium. Coral Bells pair excellently with echinacea, because they have similar requirements and help each other grow in different ways.

– Aesthetic Features

Unlike the last few flowers on this list that came with their distinctive colors, coral bells offer a wide range of colors in their flowers and foliage: cream, lavender, green, orange, and tan. All these colors, mixed and matched with the purple hue of echinacea, make for a fantastic scene in your garden of echinacea.

Coral Bells pair excellently with echinacea

The colorful foliage is the most striking feature of the coral bells. They have large leaves that can be heart-shaped or rounded. Many of these leaves are variegated, which adds even more variety to their looks. 

– Characteristics

Many coral bells are evergreen plants, bringing year-long interest to every garden they settle in. They also attract pollinators, who help spread the flowers to all corners of the vegetable garden.

– Pairing Benefits

In addition to providing visual beauty, coral bells protect against herbivores like deer and rabbits. Coral bells give off an aroma that the deer avoid at all costs. Note that this layer of protection keeps coral bells and their companion echinacea safe from these foragers. 

5. Bee Balm

Bee Balm is a member of the mint family, and it is commonly a perennial plant.

Bee Balm Specific Needs

There is also no complex seeding technique involved with these flowers. In fact, as far as the plant is concerned, you can throw the seeds anywhere and it would still grow.

– Characteristics

To the visual upgrades to your wildflower garden, bee balms protect your garden dwellers, just like several other entries on this list. They are deer resistant, keeping those grazers away from your garden. The bright nectar-filled flowers attract many pollinators that spread the seeds to all the corners.

– Specific Needs

Be aware that bee balms are especially susceptible to developing mildew on their leaves without proper air circulation and excess moisture. Mildew is a fungal disease that affects plants due to excess humidity. You must make sure your area does not have these conditions before planting them! 

6. Blue Phlox

Blue Phlox (Phlox divaricata) are perennial wildflowers that are excellent companions for echinacea plants.

Blue Phlox are natural dwellers of forest floors, making them an exceptional addition to your wildflower garden. They bloom with refreshing colors such as rose, violet, and lavender. These colors blend perfectly with the colors of echinacea, in your garden. Overall, they will fit right in with the scenery and play a large part in enhancing it.

Blue Phlox drought-tolerant

– Pairing Benefits

Blue Phlox is a great gathering hub for pollinators such as hummingbirds, butterflies, and bees. 

Like all other entries on this list, blue phlox flowers thrive the best in rich, fertile, moist, and well-drained soil. This soil provides the necessary water without the chance of overwatering, which could result in root rot.

In addition, keeping these flowers in their optimal environment is essential, as too much humidity and moisture can cause mildew infections.

Even though it is preferable to keep the blue phlox and echinacea at their ideal conditions for maximum benefit, they can still tolerate harsh conditions such as dry or clay soil. It is drought-tolerant as well.

7. Butterfly Milkweed

Butterfly Milkweed (Asclepias tuberosa) is a widespread flowering plant found everywhere, including roadsides, fields, rocky woods, and botanical gardens.

In addition to ornamental beauty and benefits, butterfly milkweed has a medicinal history, providing an effective cure for pleurisy and other ailments of a respiratory nature.

8. Salvia

Salvia (Salvia farinacea) is also called Blue Sage and Mealy Cup Sage. It is a captivating member of the mint family.

These plants are drought resistant, hardy, and require the same growing conditions as their companion plant, coneflowers. Note that following are some beautiful plants that would go very well with coneflowers. They complement each other’s beauty and grow side by side without harming one another.

9. Stonecrop

Stonecrop (Hylotelephium) is another perennial plant that shares the characteristics of echinacea and offers most of the same benefits as the other plants so far. However, it packages all of this in a rather bushy facade, particularly the flowers, which makes it distinct from the rest.

– Aesthetic Features

Stonecrops allow you a choice between several colors of unique shades to look perfect together. These colors include pink, white, purple, yellow, red, etc. You can pick the one that best complements your garden’s look, as they all pair well with echinacea.
