Light
Coneflowers of all kinds thrive in full or partial sun, tolerating the heat without a problem. These plants need at least five hours of sunlight a day.
Water
This plant is drought tolerant. It only needs about an inch of water every week.
Soil
Coneflowers prefer well-draining fertile soil. However, it’s not a fussy plant and can still live in poor soil.
Temperature and Humidity
Most coneflowers are cold-hardy in zones 3 to 8, including the Firebird variety. This means that they can be grown in most areas of the USA. They love the hot, dry heat of summer and can handle some humidity but do not like moist, soggy soil.
Fertilizer
At planting, you can give it fertilizer or humus-rich compost but go light with it. You may end up with lush foliage but fewer flowers.
Pruning
Gardeners may deadhead the flowers for aesthetic reasons; it doesn’t promote reblooming (they will rebloom on their own).
Propagating Firebird Coneflowers
If your plant looks to be losing its vitality or overcrowding in its container or spot, divide the plants in the spring. These plants can grow from seeds, division of existing plants, or root cuttings.
How to Grow Firebird Coneflowers From Seed
These plants propagate easily from seeds. They prefer cold stratification (or storing the seeds just below freezing for two to three months, such as a fridge or freezer door). Warming up triggers the growth cycle for the seeds. Plant the seeds in the spring well after the last frost with temperatures in the 60s. Plant the seeds 1 to 3 feet apart. Germination begins after about 4 weeks. After 12 weeks, you should start seeing several sets of leaves. Unfortunately, coneflowers usually do not flower the first growing season.
Potting and Repotting Firebird Coneflowers
Firebird coneflower is a good selection for planting in outdoor pots and containers. It can grow about 3 feet tall and 3 feet wide. As far as the type of container, it makes a great thriller centerpiece. Plant it near the center of the pot surrounded by smaller plants that are “fillers” to fill in the spaces and “spillers” that spill over the pot. When growing plants in outdoor containers and baskets, they often require more frequent waterings than they would in the yard or garden.
Overwintering
You may need to give the plant some protection in the first winter in your garden, but after this, they are tough and rugged.
