10 Seeds Bidens pilosa Black Jack Daisy Annual Flower

Bidens pilosa, commonly called Black Jack or Spanish needle, is a warm-season annual known for its cheerful, small daisy-like blooms with bright yellow centers and white petals. It grows quickly in sunny gardens and containers, attracting pollinators and adding a relaxed, naturalistic look to meadow-style plantings.

Often used in wildflower mixes and pollinator gardens, Black Jack Daisy produces abundant airy blooms through the warm months and readily self-sows where conditions suit it. It pairs well with grasses and other annuals in informal borders and cut-flower patches. For best results, direct sow after the last frost or start indoors for earlier bloom.
