Fancy becoming a green guerrilla? It’s easy with a few Flower Grenades. Designed to introduce vegetation to derelict urban spaces, these biodegradable clay ‘seed bombs’ are packed with soil and various seeds, including ryegrass, poppies and buttercups. Simply chuck ‘em into any neglected urban deadzone to transform it into a blooming garden of greenery. Concrete jungle? Bleurgh!

Throwing the Flower Grenade The clay pieces of the smashed Flower Grenade Poppy flowers fully grown

Launch onto a derelict site

The clay will dissolve
entirely in the rain

Watch the flowers grow!

Flower Grenade Packaging

Cool packaging

If you are wondering what’s in it for you, allow us to explain. There are over 175,000 acres of derelict land across the UK. So unless you want to spend the next few years staring at ugly scrubland littered with broken toilet seats, plastic bags and mattresses, we suggest you get lobbing pronto.

Think of it as your civic duty. The good-for-nothing government will hate you for it, so everyone’s a winner! Besides, the grenades dissolve in the rain, so even confused curtain twitchers can’t complain (unless you’re a really bad shot). It’s like being naughty and nice at the same time. Banksy Titchmarsh? GRENADE!

Customer Reviews

I planted these and all I got was grass. Disappointing.

Firebox says: Sorry to hear that Sally, why not get in touch, and we can help fix this. (
Got these for my dads birthday, he had fun lobbing them around the garden but god knows what the neighbours thought!
Siobhan, Manchester - 25th November 2010
I love the idea of these, but ryegrass is really invasive and very hard to get rid of - please please leave these seeds out!!!
