Next project: LONG border of marigolds with...???
Since I have such wonderful luck with marigolds, I have this massive project that I'm planning on undertaking next season: lining my entire driveway (300 ft+) with marigolds. My question is: what companion can I plant WITH them that will also flower throughout the whole season into fall until frost sets in? My marigolds are still going & going & going, and I'm very happy with them, so want something that is equally as hardy & low maintenance.
