Brown-eyed Susan is a cheerful, frost-hardy perennial that thrives in zones 4 through 4, reaching 30 to 48 inches tall with a compact 12 to 18 inch spread. This Rudbeckia triloba variety blooms reliably from summer through fall, attracting pollinators while shrugging off deer and drought with equal grace. The plant's moderate water needs and tolerance for full sun make it a low-maintenance addition to any garden, and its seed germinates quickly in warmth, ready to flower in the season ahead.

Brown-eyed Susan flowers from June through November without fussing, a long season that keeps color in the garden well past frost. Deer leave it alone, drought doesn't stress it, and pollinators flock to its blooms. This is the kind of plant that rewards neglect: full sun, moderate water, and it handles the rest.
Brown-eyed Susan serves as a pollinator magnet in sunny borders and wildflower meadows, drawing bees and butterflies throughout the warm months. Its extended bloom window makes it valuable for creating continuous color in native plant gardens, and its compact height suits it to the middle or front of perennial beds where it won't shade shorter neighbors.

Stratify seed for 30 to 60 days by mixing with damp sand or vermiculite, sealing in a bag, and refrigerating at 35 to 40°F. Check regularly for germination and transplant seedlings as they emerge. After the chill period ends, sow into containers and maintain lightly moist conditions. Germination occurs within 10 to 30 days following the stratification period.
Harden off seedlings before transplanting outdoors after the last frost date. Space plants 1 inch apart or 12 to 18 inches for mature width, depending on desired density. Transplant into prepared soil in full sun.
Direct sow in fall to early spring into prepared soil. Surface sow and lightly press seed into the soil; do not bury.
