Overview
Black-Eyed Susan is a cheerful native wildflower featuring bright golden-yellow petals radiating from a dark brown or black central cone. This heirloom variety matures in 100-120 days and thrives in full sun to partial shade with minimal care requirements. Highly adaptable to various soil types, it prefers well-drained conditions and tolerates poor soils where many plants struggle. The flowers bloom prolifically throughout summer and fall, making it excellent for pollinator gardens, naturalized plantings, and cut arrangements. Though occasionally browsed by deer, it resists most pests effectively. Primarily grown for ornamental and ecological value rather than culinary use.
