Guerrilla Sunflower Plantings to Happen All Over the City Tonight

Who knew? May Day is much more than immigration. In addition to being Buy Indie Day, it's about guerilla gardening, too. Specifically, it's International Sunflower Guerrilla Gardening Day.
That means that the good clandestine folks at Los Angeles Guerilla Gardening are participating and encouraging others to do the same. At this moment, it's too late to order a delivery of seeds from the group, but that shouldn't stop you from doing it anyway--everyday can be guerilla gardening.
If you want to get your own seeds, the best way to go is with native ones. But there's one problem: they are hard to come by, oddly enough. "Most big box stores don't have what's appropriate for the climate," explained LA Guerrilla Gardening operative Mr. Stamen over the phone. He suggests you head to the Theordore Payne Foundation--the group behind the California Wildflower Hotline--for some native seeds (about $4 a packet).
Another challenge is time of year. This is an international event, but for Southern California, this is not the best time to be planting. Mr. Stamen says a little more watering than usual will be needed.
About 50 sites will be planted tonight around Los Angeles (here's a map). LAist might be doing one, but you never know.... this is guerrilla! (thanks, GreenLAGirl)
