Salvia lavandulifolia ssp. vellerea - 1 litre pot
Another rarely-grown species, these are cutting grown plants taken from my one plant that I managed to germinate from seed sent to me under this name. I am yet to see what colour the flowers are, but so far the gorgeous soft grey foliage and contrasting dark stems are enough to make me want more of it. It is growing in a gravelly soil with good drainage and little water other than when it rains, so is presumably very drought hardy. Approximate size to date is 60-70cm high by 60cm wide. 1 litre pot.
