WE HAVE GROWN A NUMBER OF THESE FROM LAST YEARS SEEDS AND HAVE LOTS OF GROWTH BUT AS YET NO FLOWERS IS THERE A REASON OR SHOULD I PULL THEM OUT
There are more than 2 dozen native black-eyed susans. A common one, Rudbeckia hirta is a biennial. Usually that means they flower the second year although they might bloom late in the first year. Look up the type of black-eyed susan you have. Some are annuals, biennials and some are perennial. By having different varieties, you can ensure something is in bloom all summer and much of fall. Collect seed if you wish or let them self-sow. The annual and biennial ones are reliable self-sowers.
