Saw this on the roadside today, any idea what it is and is it available to buy,
Cuckoo flower aka Lady's smock - Cardamine pratensis - a lovely native flower of old damp meadows - getting rarer and rarer
It is also the food plant of the orange tip butterfly, another reason to have it in the garden!
Yes, Simon, the Cardamine pratensis is a favourite flower of the Orange-tip butterfly (Anthocharis cardamines). Here are two pics of the butterfly and the plant I took a few years ago of that lovely butterfly, now become too rare, unfortunately.
