as the nme implies, minor is smaller! minor has a smaller more

ground-hugging habit than major (which, IMHO can look a bit
straggly)
ISTR than minor has a lot more varieties available too.

There is also a really nice varigated variety...........

Thank you, the pics in my book both looked the same!

V. minor grows to about 6" high, and V. major to about 1'; the latter
is more drought resistant, and can be a real thug. I have just shorn
mine down to ground level to get it back under control - yes, that is
one way to prune it :-)

If you are in this area, and want some V. major "oxyloba" (a very
different strain, with lighter leaves but much darker and more spiky
flowers), please ask. For reasons I cannot understand, it is rarely
stocked. It is a much better than the common one in several respects.
