Spring has finally sprung and flower grenades make gardening a blast. Made from compacted clay, the grenades contain soil, wild grass seeds and wild flower seeds. Give the kids a couple to lob and your back yard will soon be awash with the colour. Best of all, there's no tidying up: the clay returns to the soil without you having to sweep up the mess. Available at Designist (01-4758534, designist.ie) at 68, South Great Georges Street, Dublin 2. New stock will be in store for March 31st. They cost €17.50.
