The predominant variety (I would say) is Ling, intermingled with Bell (which I documented a few weeks ago). I definitively was NOT going to draw the Ling with it's ridiculously fiddly detail, but in the end succumbed because it would be an injustice to the Exmoorland colours to leave it out...so just a small branch..!
(Off on a slight tangent... In the language of flowers, Heather can mean Protection,
which reminded me of this great song (and album) by Massive Attack in 1994 with Tracey Thorn).
