Blackjack Gold Black-Eyed Susan (Rudbeckia triloba) is an improved form of the native Black-Eyed Daisy, bred by Jelitto Seed of Germany to bloom longer and be decidedly perennial. Normally a re-seeding biennial, 'Blackjack Gold' will attract numerous butterflies when in flower and seed-eating songbirds during the fall and winter. Perfect for bouquets. A nice companion plant for Panicum grass as well as red Bee Balm (Monarda), Joe Pye Weed (Eupatorium) and Phlox paniculata 'David'.
