Which of the following is also known as Purple Coneflower?

Purple Coneflower is scientifically known as Echinacea purpurea. This plant is part of the Asteraceae family and is recognized for its distinctive purple petals surrounding a prominent central cone, making it a popular choice in gardens due to its aesthetic appeal and ecological benefits. Echinacea purpurea is valued not only for its ornamental qualities but also for its medicinal uses, particularly in herbal remedies aimed at boosting the immune system.

In contrast, Cyrtomium falcatum, commonly known as Japanese holly fern, belongs to a different family of plants and is a fern rather than a flowering plant. Carex sp., commonly referred to as sedges, are grass-like plants that serve different ecological functions, often growing in wetlands or as ground cover. Coreopsis sp. includes various flowering plants known as tickseeds, which differ significantly in appearance and habitat from Echinacea purpurea.

Thus, the association of Purple Coneflower with Echinacea purpurea is well-established due to its distinct characteristics and usage in horticulture and herbal medicine.
