Description
Cosmos bipinnatus 'Afternoon White' features delicate, pure white petals surrounding vibrant yellow centers, creating a serene and elegant display in any garden. This variety is known for its airy, fern-like foliage and prolific blooming, making it a favorite for adding height and texture to flower beds or as a backdrop in mixed borders. As an annual, it completes its life cycle in one season but self-seeds readily for future growth. These plants are versatile, thriving in average soils without needing rich fertilization, and they attract beneficial insects while providing long-lasting cut flowers.
Transplanting Instructions
Transplant these 3" potted starters outdoors after the last frost date in your area. Choose a sunny location with well-drained soil. Dig a hole slightly larger than the pot, gently remove the plant, and place it at the same depth it was growing in the container. Space plants 9-12 inches apart. Water thoroughly after planting and keep soil moderately moist until established. Pinch back young plants at 6 inches tall to encourage bushier growth and more blooms. Avoid over-fertilizing, as it can lead to leggy stems; cosmos prefer lean soil for best performance.
