I have a bed in front of my house (part sun, northern exposure) where I've
tried some annuals that are supposed to reseed (marigolds, sweet allysum,
coreopsis, and something else I can't remember now), but nothing ever comes
back. I'm wondering if there's something I should be doing to encourage
them, short of collecting seeds & sowing them the next spring.
