I've always been fond of the pretty little sweet-pea flowers of vetch.
More recently I've learnt that it can be used as a green manure as, in common with other legumes, it fixes nitrogen from the air and so enriches the soil. For this use, it seems to be known as tares.
However, neither of these valuable attributes are the point of this blog post. As you've probably guessed by now, vetch is also edible. I believe you can eat the immature seeds, just like peas, but they're tiny and really not worth the bother. I've tried eating the pods, but the lining is very tough and scratchy, so I wouldn't bother eating that bit either. No, the part I eat is the young leaves (which are also edible in garden peas).
You do have to watch out for ants when picking these.
I've found that the purple-flowered variety has broader, softer leaves than the other colours. Luckily, this is the kind I have most of in my garden. They can be eaten raw but I usually steam them for five minutes or so, as I would for any other leafy vegetable. They taste somewhat like peas and are definitely worth harvesting, especially as they're so abundant. So, vigorous to the point of invasive, pretty flowers, tasty leaves (and seeds if you can be bothered) and they're good for the soil. What's not to like?
