Lathyrus grandiflorus



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.



An easily grown spreading perennial which can become invasive, particularly in light soils. At its best allowed to sprawl down a bank. Because of its reluctance to set seed, Lathyrus grandiflorus normally has to bought as a plant. It can easily be propagated from its running rootstock.
