91-105 days. Goldilocks seeds grow a tidy yet spectacular twist to the traditional daisy-like rudbeckia. Goldilocks seeds mature as neat 15 inch tall dwarfs overgrown with generous 3-4 inch sunburst yellow semi-double and fully double blooms. Goldilocks rudbeckia debuted as a Fleuroselect Gold Medal Winner for its "masses of large double and semi-double flowers" and being "very adaptable and performing well in most soil types and climatic conditions." Rudbeckia Goldilocks seeds are an ideal grow for window boxes, baskets, and indoors or hardy enough fill out a flower bed for rich, abundant color up until the frost.
