The Wort we do have around, but it's not an early bloomer here. Actually as of today (warm) it looks like a bunch of normally later things are about to bolt anyway. Not surprising with the crazy cold weather.
I'm not sure if boxwood is hardy enough for us. Florists do love it... Of course as with other shrubbery, it it grows two feet tall that'll be 2 inches after the rabbits find out!
