Lathyrus odoratus 'America'is an heirloom variety from the late 1800's. The blooms are very sweet smelling and pinkish white with rose marbeling. It is a late bloomer.

Plant seeds outdoors after last frost in cooler climates, 1" deep, 2" apart. In warm climates, seeds can be planted in the fall. When seedlings are up, thin to 3" apart. If starting indoors, allow 4-6 weeks before setting out. Soaking seed can hasten germination. Germination: 10-15 days.
