The plants are bigger than plugs and therefore more expensive. It
depends upon how impatient you are. Oh and before Jeff picks me up on
it, when commenting about greek or balkan sage (Salvia fruticosa) I
meant to write triloba and not triphylla as being the synonym.
Anyway, you'll have to hunt around for that, but it is variously
available from places that specialise in Salvia sp.
