Vernal Sweet Pea is one of those reliable early spring bloomers that is seldom found in garden centers. Propagated by seed, it forms an 18″ mound of beautiful blue-purple sweet pea flowers in April and early May. Plants look great for the rest of season with occasional watering. Lathyrus vernus needs a humus rich but well drained soil to thrive.
