Probably half hardy perennials, shelter from winter weather in a greenhouse or similar to get them through. Unless they're half hardy annual ones, in which case, bin them at the end of the season.

Rudbeckia hirta is a biennial to short-lived perennial which usually looks best the first year it flowers--I would bin them this fall. Other Rudbeckias are hardy perennials which just need a short haircut in earliest spring to leave the new growth unimpeded.
