Thats more or less how Betty got it! apparently found on a house front in
the mid west and taken all the way to Texas as a cutting in a potato.
Still has the best scent of any summer flowering clematis.


It is a lovely little plant and has done really well up my pergola this
year, flowering for ages. Not too showy but a steady display of flowers.
I just regret that, at a distance, the flowers are difficult to make out
amongst the leaves.
