Yes... I love reading that book which I called by the wrong name above, it should have been Southern Herb Growing ~ another senior moment.
I have also read interviews with Ms Hill in herbal magazines and she was so knowledgeable and entertaining.
I love the scented geraniums but have killed far more than I should have.
Cameron ~ she recommends that English lavender be treated as an annual in the humid south ~ that's me! But she says in Central and North Texas you should be able to grow these successfully. Recommended to "plant in the driest area you have, in full sun, and neglecting them a lot."
Good luck if you try them and please post your success with it.
