Rudbeckia lanciniata
This taller cousin of the black-eyed Susan spread enthusiastically via rhizomes, so is best suited to larger landscapes. ~80 seeds/packet.
Please note, for Canadian customers, seeds can be sent as untracked lettermail. Our website will charge you the regular flat-rate for shipping, but if your order only contains seeds, we will refund you the excess fee above the price of the stamp.
