This fact sheet describes sweet pea cut flower production in Utah, Planting sweet peas early in the year provides extended, cool-season conditions that are critical for producing a high quality crop and maximizing yield in Utah. High tunnels allow for earlier planting than in the field and therefore, a longer growing period under cool temperatures. In our conditions, Elegance and Mammoth series had the greatest number of marketable stems and are recommended for Utah sweet pea production. Color trends and market demands should also factor into cultivar selection if growing for the cut flower industry.
