Have you heard of guerrilla gardening, where folks toss flower seeds into vacant lots, or sometimes sneak in at night and plant flowers in unkempt highway medians or strips along city sidewalks? One of their tools is seed bombs — little clumps of dried mud laced with seeds that can easily be tossed over fences into vacant lots. Top choices for best seeds to sow are tough, native species, which you might think would be hard to come by. Think again — one of the showiest and toughest native plants is actually also one of the cheapest and most widely available — the sunflower seeds, sold for birdfeeders, in pretty much every supermarket and hardware store across the country.
Seems like a great way to celebrate Earth Day. No need to pack the sunflower seeds into mud balls — just toss a handful onto bare ground pretty much anywhere that won’t be mowed, and a couple months later you’ll see the showy yellow flower heads of tall, sturdy sunflowers. Birds will love the seeds, and most likely miss a few, leaving them to bloom the following years.
