We have several hawthorns planted in the median between the neighbor's driveway and ours, against a fence.
I have no previous experience with hawthorns and did not expect them to be so graceful. They do not have a very positive reputation, which I am assuming is because of the scent some of them have (which I have seen described as "rotting flesh.") The scent of mine is luckily that typical faint musk of spring-flowering stone fruits. It's not my favorite scent, especially up close, but on the air it is a little sweeter and not bad at all. These are blooming in late February.
Looking at the leaves and flowers, the closest I've been able to get to a possible identification is Crataegus punctata, but there are many sub-species that I haven't seen, so I could very well be wrong.
There is a white-flowered form with yellow anthers, a pink-flowered form with burgundy anthers and leaves, and a cream-colored form with burgundy leaves. They are beautiful when in bloom and in leaf, the pink one especially. I just love looking at them and wish they kept their flowers longer.
Even though I am not able to identify the species definitely, I read that the fruits and young leaves of all hawthorns are edible (but not the seeds.) The berries are high in pectin (though apparently flavorless,) C. monogyna so much so that it can make a jelly without cooking, which sounds like a lot of fun to me. I am looking forward to seeing what mine will do.
Also I read in Wikipedia that in Gaelic folklore hawthorn marks the entrance to the fairy world, and is referred to in the entry as "fairy thorn." I like that.
