Lathyrus odoratus. The best sweet pea choice for warmer climates or gardens, Old Spice Blend sweet pea seeds are a mix of old heirloom varieties that have weathered the test of time. Solid colours and some streaked flowers appear in cream, rose, white, pink, and purple on long stems that you’ll want to bring inside as cut flowers. This is a good climber that deserves a stout trellis to support vines that grow to 120cm (48″) tall. Make sure to keep the vines picked of all spent flowers and seed pods, and they will reward you with a very long flower period. Old Spice blooms after Mammoth, but before the Spencers.
