I had a rosemary bush growing against a sout facing wall - it turned out to be a right thug! Like Topsy it growed and growed..... it seemed to be in ideal conditions. Next time I plant rosemary I intend to put it in a pot!
Did you know you can make a nice rinse for your hair with it? Pour boiling water on a few sprigs in a nice big jug and leave to infuse (and cool) then when washing your hair pour the infusion over your hair in the last rinse, not only will it smell quite nice, it'll add to the shine and make long hair less likely to tangle. I used it a lot on my daughter's long hair when she was young - it used to get very tangled when washing. Mind you only use it if you're a brunette - not suitable for blondes or redheads
