If you have ever wondered what a grown up mustard seed looks like.. here one is! We planted a whole load of the seedlings in our herb garden a few months ago, and now they are huge flowering mustard plants! I wouldn't recommend eating the leaves though.. they are all hairy and not very appetising! After I spent ages assuring James that they were edible, we both tried a leaf, and both ended up spitting them out! I think maybe it's best eaten like cress when it's only a few days old so it doesn't actually prickle your mouth!
