Seed Bombs or seed balls, are small clusters packed with wildflower seeds that are designed to bring greenery and colorful pollinator habitats to urban landscapes or neglected areas.

Born from the guerrilla gardening movement that took shape in the 1970s, seed bombs were first used en masse by artist Liz Christy and the Green Guerrillas. Tired of Manhattan’s crumbling concrete sprawl, they began tossing what they called seed green-aids (sounds like grenades, get it?) into abandoned lots and run-down urban landscapes.
