Commonly know as catmint, this is a family of around 250 species. I find this amazing as you are lucky if most garden centres even stock one! They originate from southern Europe right across into Asia and are found in hot dry conditions. The normal garden catmint is racemosa or mussinii which loves a sunny spot and will form a mass of soft grey foliage up to 1 meter accross and will flop casually; looks great over a low wall or at the edge of a border spilling onto gravel. We also stock the smaller nervosa which is a bit more shrubby and has greener leaves. This is more contained in a smaller space.
Bees (and cats) love it and you will see the whole range of short-tongue varieties (bumblebees, carders, mason and honeybees). The reason cats go potty is it gives of a scent that has a weird effect on them like a temporary 'high'.
