What is Echinacea and How is It Used?
Echinacea, or coneflower, is a hardy, sun-loving perennial. It is a versatile plant with a variety of uses, ranging from ornamental to medicinal. Echinacea is a popular choice in flower gardens and landscaping due to its striking flowers and ability to attract pollinators like bees and butterflies. The blooms make excellent cut flowers, adding vibrant color to arrangements and bouquets.
The flowers can be used to create natural dyes, producing shades of pink or purple, which can be used for textiles and crafts. The blooms and leaves are edible, so may be used to decorate food for floral-themed parties. Echinacea can be used to make herbal teas or tinctures, which are consumed for their potential health benefits. Echinacea is a versatile, easy-to-grow addition to an herb, flower, or potager garden.
Echinacea Companion Plants Backstory
A few years ago I was given some echinacea seeds as a gift. I was so pleased to learn that echinacea is a perennial that will return every year, plus it was easy to grow in my USDA Zone 8 garden. Since that first success with growing echinacea, I have planted it in a variety of different places around the yard. It’s easy to move the plants or collect the seeds to increase the number of echinacea plants in your yard or garden. Read on to learn more about this amazing low-maintenance perennial.
Echinacea Companion Plants: Perfect for a Potager Garden
A potager garden is a French-style kitchen garden that combines the practical purpose of growing vegetables, herbs, and fruits with an aesthetic, ornamental design. Unlike traditional vegetable gardens, a potager garden focuses on beauty as well as functionality. Plants are arranged not only for visual effect but also to promote growth. Echinacea is ideal for a potager garden because of its attractive blooms as well as its many uses.
A potager is designed to look attractive in all seasons. This may include evergreen herbs, perennial flowers, or structures like arbors and trellises to provide visual interest even when crops aren’t in bloom. Here is my little potager garden. I have echinacea, chives, and rosemary planted together near our garden trellis and grape arbor. It’s definitely a work in progress!

What Not to Plant with Echinacea
While echinacea pairs well with many plants, there are some plants you should avoid planting near it due to competing needs or potential negative interactions. Here are some plants not to plant with echinacea:
Plants that Require Excess Moisture: Astilbe prefers consistently moist soil, which can lead to root rot for echinacea. Japanese Iris thrives in wet conditions, creating competition for moisture.
Tall Plants that Shade Echinacea: Sunflowers attract pollinators, but their height can shade echinacea, limiting its sunlight exposure. Tall perennials like hollyhocks can overshadow echinacea and hinder its growth.
Plants Prone to Fungal Diseases: Peonies can harbor fungal diseases that might spread to echinacea, especially in humid conditions. Hostas can also be susceptible to similar diseases, which may affect nearby echinacea.
Aggressive Growers: Mint is known for its invasive nature, and can quickly overtake garden space and compete for nutrients and water. Vinca (Periwinkle) is another aggressive plant that can spread rapidly and outcompete echinacea.
Plants with Similar Nutrient Needs: Plants in the Cabbage Family (Brassicas) may compete for the same nutrients, potentially affecting echinacea’s growth.
Plants that Attract Pests: Certain types of vegetables, such as tomatoes and peppers, may attract pests that could harm echinacea.
Plants with Different Light Requirements: Shade-loving plants like ferns or hostas that thrive in shaded areas can compete for resources and do not share the sunny conditions echinacea prefers.

Echinacea Planting and Growing Tips
When is the best time to plant echinacea?
The best time to plant echinacea (coneflower) is in spring or early fall.
Spring Planting: Plant echinacea after the last frost date in your area, typically between late April and early June. This allows the plants to establish their roots during the warmer growing season. Spring planting takes advantage of the longer days and warmer temperatures, promoting faster growth and robust flowering.
Fall Planting: In early to mid-fall (September to October), plant echinacea a few weeks before the first expected frost. This gives the plants time to establish roots before winter. Fall planting allows echinacea to benefit from the cooler temperatures and natural rainfall, reducing the need for watering. It also means the plants will be ready to bloom earlier in the spring. Echinacea plants drop their seeds and can naturally reseed in the fall.
Where is the best place to plant echinacea?
The best location to plant echinacea is in a sunny spot that receives full sun, ideally at least 6 to 8 hours of direct sunlight each day. Echinacea thrives in well-draining soil with a pH between 6.0 and 7.0. You can monitor soil pH level with a handy meter like this one.
Echinacea plants prefer a slightly dry environment, so avoid low-lying areas where water may accumulate. Incorporating organic matter can improve soil quality and drainage. Planting echinacea in these conditions will promote healthy growth, vibrant blooms, and attract beneficial pollinators to your garden.
How much water does echinacea need?
Echinacea (coneflower) requires moderate watering, particularly during its establishment period. Here are some key guidelines for watering echinacea:
Newly planted echinacea should be watered regularly—about 1 inch (2.5 cm) of water per week, either from rainfall or supplemental watering, to help establish strong roots.
Once established, echinacea is relatively drought-tolerant and typically needs water only during prolonged dry spells. Watering should be reduced to about 1 inch (2.5 cm) every 1-2 weeks depending on weather conditions.
Always check the soil moisture before watering; the top 1-2 inches (2.5-5 cm) of soil should be allowed to dry out between waterings. Overwatering can lead to root rot, so ensure the soil drains well.
During periods of consistent rain (like what we often have here in Oregon), additional watering may not be necessary.
What is the best fertilizer for echinacea?
The best fertilizer for echinacea is a balanced, slow-release fertilizer with an N-P-K ratio of 10-10-10 or 5-10-10. This ensures that the plants receive an equal supply of nitrogen, phosphorus, and potassium, promoting healthy growth, strong root development, and abundant flowering. It’s advisable to apply the fertilizer in early spring when new growth begins and again in mid-summer to support blooming. Additionally, incorporating organic compost or well-rotted manure into the soil can enhance nutrient availability and improve soil structure without overwhelming the plants.
How to Make Echinacea Tea
Ingredients
1-2 tablespoons chopped fresh echinacea leaves and flowers
1 cup of water
Optional Additions: Honey, lemon, or other herbs (such as ginger or peppermint) for flavor
Instructions
Bring water to a boil in a saucepan or kettle.
Once the water is boiling, remove it from heat.
Add the measured echinacea to the hot water.
Cover and let it steep for about 10-15 minutes for the best flavor and health benefits.
After steeping, strain the tea through a fine mesh strainer or cheesecloth to remove the plant material.
Optional: You can enhance the flavor of your echinacea tea with a drizzle of honey, a squeeze of lemon, or other herbs and spices like ginger or peppermint.
It’s generally safe to drink echinacea tea 2-3 times a day, but consult with a healthcare provider for specific recommendations, especially if you have health conditions or are pregnant.
Propagating Echinacea
The best way to propagate echinacea is through seed stratification and planting. Collect seeds in fall, then cold stratify them by placing them in moist sand in the fridge for 4-6 weeks to improve germination. Sow seeds in spring or late fall in well-draining soil, and keep the soil lightly moist. Alternatively, division in early spring or fall is a faster method; simply dig up the plant, divide the root ball into sections, and replant. Both methods are reliable, though seed propagation takes longer for plants to mature. Here are some of my echinacea plants going to seed. The seeds of echinacea are very easy to save.
