The name Lathyrus grandiflorus is sometimes mistakenly applied to the grandiflora type sweet peas of the species L. odoratus. Unlike the sweet peas which are annuals, L. grandiflorus is a robust perennial with a running rootstock. It is a showy plant, flowering in early summer, but rarely setting seed in the UK. There is a nice photo of the flower on the De Mashut website.
