Everlasting sweet pea

It has been a bad year for ordinary sweet peas, which have the benefit of scent. Lathyrus  latifolius, the everlasting sweet pea comes back year after year. The top one was growing over the floor and through the chair (middle until I tied it up). Scrambling is its great strength, and it can crawl through bushes and beds giving a boost of unexpected flower (bottom picture with a mauve/purple pea).

Here the purple lathyrus is joined scrambling around, by white cosmos and red crocosmia.
