Mint Bush. We love the genus with the aromatic, deer-proof evergreen foliage and in this case, white flowers tinged lavender. A Welsh nuseryman describes it as "a cracking plant tolerant of heavy frost and sells on sight".

Alpine Bush Mint.  This high elevation Aussie handled our 2010-11 Winter of Horror with scarcely a whimper.  Dense shrublet with rounded packed leaves minty when crushed and white flowers with red-yellow-purple in the throat from spring and sporadically until fall.  Excellent plant.
