Rudbeckia Seeds

Giant 5 in. wide yellow blooms with primrose tips and green eyes. Prairie Sun rudbeckia puts on a stunning display in the garden from early summer until frost. Both plants and flowers show incredible heat tolerance; they remain fresh and healthy even when temperatures reach well over 100° F. Prairie Sun will also thrive when grown in more moderate temperatures.

Prairie Sun rudbeckia is definitely high on our list of recommended flowers for your garden. Flowers attract butterflies and are excellent for cutting. The 3 ft. tall plants stand up to heat and are incredibly showy when massed. An All-America Selections Winner and a winner of the Fleuroselect Gold Medal (Europe's top prize).
