Can rudbeckia seedlings handle light frosts?
I have a bunch of annual rudbeckia seedlings (Indian Summer, Tiger Eye, Prairie Sun, Cherockee Sunset, Maya) that have already been planted out. We're anticipating a light frost this coming Monday and Tuesday (to 34 degrees). Will the rudbeckia seedlings be able to withstand light frosts? My experience is that petunias are able to withstand frosts, though they are annuals, so I'm hoping that the same is true of the rudbeckias. (In fact, last fall my petunias continued blooming even when the nighttime temperatures briefly dipped into the 20s for weeks.)
