Rudbeckia triloba, Brown Eyed Susan

Smaller flowers, three lobe leaves, and its branching habit make Rudbeckia triloba, aka Three-lobed Coneflower (the 'susan' names are being phased out), stand out from the more common biennial Rudbeckia hirta (the other 'susan'). Threatened in the Minnesota, this is a fairly common garden plant. This perennial is short-lived, but will spread by seed in disturbed, open spots just like its cousin, the other susan.

Blooms: yellow, July into September

Height: 3 to 5 feet
