@Jon; reminds me of the time a new gardener quoted me a ridiculous figure for buying plants for an area of garden; I told him it was daylight shrubbery...
@Paul, hehe, very funny. I did wonder if Thyme was a shrub or a herb, online sources seem to be divided on the subject. I went with Chambers which calls it “half-shrubby” whatever that is.
if you regard "herb" as a function rather than not being woody, plants can be both shrubs and herbs at the same time. bay leaves are used as herbs in cooking, and they grom on trees!
