Ah, good to know. I don't know if I've experienced rust, but I do know I usually end up with random snaps the 2nd year, not as prolific as the freshies, but certainly welcome. This is a bed I have been trying to populate with reseeding annuals, largely unsuccessfully. I do get poppies (field and CA) to reseed, but was surprised to lose both borage and calendulas. Maybe I'd have better luck to try to save seed and start things inside.
