I'm not sure it is wise to plant crow garlic out or best ensure it is well contaned and any bulbils that form in the flowers are not allowed to scatter (may be eat them) and don't compost them. RHS regards it as a problem weed.
Wikipedia suggests that "It imparts a garlic-like flavour and odour on dairy and beef products when grazed by livestock".
