In Cornwall, at this time of year the farmers grow fields of 'spring
greens', also known as collards. They are, as you describe, a
non-heading cabbage similar to kale, widely available in supermarkets
locally as 'spring greens' or just 'fresh greens', and very nice too.

Ah! So the name would have reached the USA from the West Country.

Whether they're the same as your collard greens I don't know, but I
suspect they're very similar.

Yes. Modern USA collard greens have been selected for better heat
adaptation (most UK brassica varieties are VERY sensitive to anything
above chilly conditions, as the result of long selection for our
climate), but I believe that is pretty well the only difference
between them and some of our kales ("spring greens" is a recent
marketing term for kale).
