It will grow in full sun or shade and is evergreen in zone 9.
Could you give us more of a description please? Its quite hard to see flower and leaf shape. Also is it scented, leaves or flowers? Are the stems round or square? How many petals on the flowers etc?
I don't think its a Salvia, although there are some Salvia species which are woody, Salvia officinalis is a good example of a woody salvia.
Ok I will try and get a better picture. It doesnt bloom the white is just the leaves, they start out green then turn white. My aunts is about 3 foot tall.
I can't think of the name! It used to be seen all the time around Houston!
