Like most members of the Pea Family, the seeds of Sweet Pea are full of nutrients, remaining viable for long periods of time. One plant can produce many hundreds of seeds during a growing season. The Sweet Pea is very tenacious and can spread for considerable distances. Blooms from April to October.
