Carbon Farming Solutions - Staple Crop: protein-oil (The term staple crop typically refers to a food that is eaten routinely and accounts for a dominant part of people's diets in a particular region of the world) [1-1]. Under development at the Land Institute to domesticate this species for use as an oilseed crop. Trials yielded 1.1t/ha of seed [1-1].

Other Uses
Oil
Garden Ornamental. Compared to other Silphium species, it is shorter, less likely to topple over, and faster from seed to flower. More manageable than most perennial sunflowers as it spreads slowly, and it is not known to be allelopathic. Adapts well to prairies, wildflower/native plant gardens, naturalized areas, meadows or moist, open woodland areas. Attracts birds and butterflies

Cultivation details
Management: Standard Staple Crop: Protein-oil Under Development
Climate: boreal to warm temperate. Humidity: semi-arid to humid. It needs full sun, poor to loamy soils, and mesic to dry conditions. Average, medium moisture, well-drained soils. Tolerates some light shade. Also tolerates some drought once established. Will grow in a variety of soils including sandy, loamy or clay ones. Cultivation: under development. Management: standard (Describes the non-destructive management systems that are used in cultivation) [1-1].
Carbon Farming
-
Management: Standard
Plants grow to their standard height. Harvest fruit, seeds, or other products. Non-Destructive management systems.
-
Staple Crop: Protein-oil
(16+ percent protein, 16+ percent oil). Annuals include soybeans, peanuts, sunflower seeds. Perennials include seeds, beans, nuts, and fruits such as almond, Brazil nut, pistachio, walnut, hazel, and safou.
-
Under Development
Plant breeders are actively working to domesticate these plants for cultivation, but they are not yet commercially available as crops. Examples include most of the perennial cereal grains.
