Sweet Pea; Lathyrus
Grow Sweet Peas (Lathyrus odoratus) in well-drained soil in full sun. These fragrant climbers prefer cool, moist soil around their roots. Either plant low-growing annuals around them to shade the roots, or apply a layer of mulch. Sweet peas thrive in alkaline soils, so add lime if your soil is acidic. For climbing varieties, provide at least 6' of vertical support at planting time.
