Lathyrus chloranthus | Also known as: climbing sweet pea, sweet pea | Rating: 1 votes | Print / Pdf

Yellow sweet pea is happy climbing or in a pot, but less happy when made into soup.

If you’re not sure where to begin with your outdoor space, you’ll certainly get a taste for gardening with lathyrus chloranthus or yellow sweet pea, a climbing plant that offers something a little bit different. The unusual yellow-green flowers look like miniature fans or sails and are a fantastic way to add interest to your garden. Yellow sweet pea likes moist sandy and loamy soils, rich in humus with good drainage . It will grow in partial shade as well as full sunlight. The climbing ability of this plant makes it a far more attractive way to decorate a bare wall than a splash of paint and it will also happily clamber up a trellis. For an alternative use, grow yellow sweet pea in a container and allow it to grow over the edge for a beautiful cascading effect.
