The cane wigwams provide just enough screening. This year I am growing sweet pea 'Matucana' up them for their strong scent and vibrant colour.. I plann to have magenta with maybe a dash of lime green or even orange.
The black chair in phot two collapsed under someone last year! Thakfully she was not hurt but new chairs are on order.
Apart from that feeding the wisteeria in the corner to see if it will flower better is the only change required for this area. It's a very happy part of the garden. Do you have a happy spot? Or plans to make one?
