How to Plant and Grow Purple Coneflower Seeds

April 21, 2009

A beautiful flower perfect for spring planting is the purple coneflower seeds. This flower is extremely hardy and is resistant to drought, making it a great flower for gardeners who live in dry areas or who don’t have a lot of time for watering their gardens. They will tolerate partial shade as well as full sun. The purple coneflower produces large flowers that have an interesting arrangement of purple petals that point toward the ground. In the center of the flower is a large reddish cone that grows into the large, colorful focal point of the flower.

The seeds can be planted anytime that the soil reaches a temperature of 70 to 75 degrees and the threat of frost is over. Choose an area that has well-drained soil for planting purple coneflower. The seeds should be planted at a depth of about 1/8″. This can be done by gently pressing the seeds into the soil so that they are barely covered. The germination time for purple coneflower seeds is about 15 to 30 days after planting.

Once the purple coneflower has sprouted, you can expect the plant to grow quickly and to bloom for a long period. In most parts of the US purple coneflower will not flower the first year. It will however flower for the next 15 to 25 years. I have purple coneflowers I planted from seed that have been growing in the same place for 15 year. The average bloom time for this flower begins in June and runs all the way through October. The flowers grow on long stalks and make perfect cut flowers for your flower arrangements. These tall flowers grow to a stunning height of up to 3 feet and can be cut with a long stem. Once the purple coneflower is cut, it will last for about 5 to 7 days in a vase before wilting. When mixed with flowers of contrasting colors, it makes a stunning and unusual cut flower that will stand out in any flower arrangement, or it can be used on its own in a coneflower arrangement. Purple coneflower is one of my favorites. The only thing I do to keep them looking good is mow them down in the fall. Make sure you pick the seeds heads off if you want more seed to plant the next year somewhere else. Keep Gardening.
