what are the benifits if any betwenn Hawthorne and Blackthore.

Blackthorn gives you sloe gin.

(well, you have to provide the gin)

Hawthorn is thorny, relatively fast growing, has flowers in about may
and red fruits in autumn which are well liked by birds. (though you
don't get as many flowers when you cut the hedge regularly)
Blackthorn is thorny, relatively fast growing, has very early white
flowers (March) and dark purple fruits.

If you're interested in wildlife, you are better to have a mixture, and
with 42 feet you have the space to do so. A mixture will also provide
you with more variety to look at, and something of interest for a
greater part of the year.
