perennial sweet peas

this plant has been growing in my garden here at 6110 since summer 2008.  it is a very pale pink sweet pea and does not have any fragrance, however; it is a wonderful cut flower and does well in full sun.  my references say that it can grow to twelve feet on a trellis, but mine is about 7 feet and droops over the trellis which i encourage. the look is very soft and appealing to me, and one that i have included in my cottage kitchen garden. 

each year, the sweet pea has become stronger and more sturdy on the trellis, though i prune it back to the ground every fall to prepare it for the winter cold and snow. it is cold hardy to zone three and one of my favorite plants in july.
