Grow the best heirloom coneflowers in your garden
Heirloom coneflowers are native to the United States and belong to the daisy family. Plant this perennial to ensure plenty of pollination for neighboring plants. Except in exceedingly arid locations, heirloom coneflowers are drought resistant and thrive on the available moisture from rain. Wildflower blends such as Eden Brothers' All Perennial Wildflower Mix and The Bees Knees Wildflower Mix feature our heirloom coneflowers and add a splash of color to any flower bed!
Prepare to grow heirloom coneflower
Prior to planting, heirloom coneflowers must be cold stratified. To achieve this, soak the seeds for one to two hours. Using a paper towel, absorb the excess water and spread the seeds out in a single layer on the towel. To keep the seeds damp but not soggy, wrap a dry paper towel around the wet one and place everything in a sealed plastic bag. Refrigerate the bag for eight to twelve weeks before you wish to plant them. If your seeds sprout before the end of the cold stratification process, take them as soon as possible and plant them indoors until they are ready to be transplanted outside.
When to plant heirloom coneflower seeds
Heirloom coneflower seeds can be planted after the last frost date in fall, or you can start them indoors six to eight weeks before the final frost date. Heirloom coneflowers thrive in average, well-drained soil in bright, sunny weather, though they may tolerate moderate shade if necessary. Because heirloom coneflower requires sunlight to sprout, put the seeds straight onto the soil's surface, compressing slightly without covering them.
Heirloom coneflower maintenance
Additional watering is not required in places with regular rainfall. Heirloom coneflowers usually don't need fertilizer unless the flowers are small or aren't developing properly. If this is the case, use a phosphorus-rich fertilizer. Reduce the height of the plants by a third when the blooms appear to be spent. This will assist the plant in re-energizing as well as conserving energy for future seasons. If not cut back, the heirloom coneflower plant will grow larger, but it is not a species that spreads or takes over other plants nearby.
