Depends on where you live.

A good start, yeah. Especially if it's a lone hawthorn.
Although you can always summon one. There are a good few methods to it, listed in The Discoverie of Witchcraft and I think the Book of Oberon? But ceremonial magic bores the hell out of me, with its lengthy prayers and conjurations that we're supposed to memorize and recite. So I'd personally not bother unless I could use a cheat sheet or find a simpler method.
