what are the benifits if any betwenn Hawthorne and Blackthore.

They are both very good hedging plants, the hawthorn tends to grow more
bushy, while the blackthorn is more towards a tree in the Prunus family.
(I occasionally make walking sticks from blackthorn branches) In both
cases, they should be clipped two or three time a year to keep the lower
part dense for hedging purposes. Birds will nest in mature specimens, so
spring clipping should be avoided.
