Another plant for the masochists out there with mischievous young children, looking for suitable revenge! Ecballium elaterium has rough sea-green leaves on wandering stems to 1m or more and yellowish flowers followed by exploding inedible mini ‘cucumbers’ from July to frosts. These fruits explode to the touch when ripe, squirting out a thick gooey mess of seeds. I have read that it is hardy to about -5C!
