29 Sweet Pea Flower Vines for Your Garden

Sweet smelling and pretty as a picture, sweet peas are a star of the late spring garden. Whether for ornamental value or use in floristry, it is easy to grow these fragrant flowers on their delicate climbing vines.

They got their start as garden plants in the 1690s when a Sicilian monk by the name of Father Francis Cupani shared the seeds he had gleaned from his cultivated plants with his gardening friends across Europe and the UK. 

The popularity of these plants has ebbed and flowed over the past few centuries, with a strong resurgence during the Victorian Era. These antique garden flowers are still popular today and make a wonderful addition to the cottage, cutting, or other ornamental garden. Here are 29 beautiful varieties of sweet pea vines for your viewing enjoyment.
