Sweet Pea Perennial Blend HEIRLOOM Seeds

Sweet Pea Perennial Blend HEIRLOOM Seeds

Lathyrus latifolius

Item #1170

Perennial. The perennial sweet pea differs from the annual type not only by its everlasting attribute, but also by the very long vine length and usually scentless flowers. The lush, trailing stems are gorgeous rambling over shrubs or fences, gracing an arbor, or used as a groundcover. Perennial sweet peas withstand summer heat extremely well, and thrive in coastal salty air. Treated as an annual in cold winter climates. Perennial in USDA zones 3-8.
