Beebombs

I've just seen a thread about sowing wild flower seeds  which reminded me that I received some Beebombs as a gift. My garden doesn't lend itself to wild flowers such as those in the Beebombs. Has anyone any suggestions as to what I could do with them? The instructions say that the ground needs to be clear but not necessarily dug, that once scattered you just leave them to do their own thing and that the flowers might not appear for 2 years (obviously biennial). Putting them where the ground will be mown such as a grass verge doesn't seem viable. It's a pity to waste them.
