Oh, I've tried to kill it. I've pulled it out several times, and it has always come back even stronger. Last week I gave up and actually sprayed it with Roundup. The primrose is not even fazed. It keeps marching on, spreading, and strangling everything in its path. Bwaaaahhhhhhh! Sat Oct 15 2005 16:20 Zombie Primrose:
Nobody warned me. I planted a six pack of Mexican Primrose last year. (I have found that things with "Mexican" or "African" in their name do well here.) The primrose has such sweet little candy-pink flowers, and it has agressively taken over.
