Please donate to support our ‘Plants to Save the Planet’ Project. The Project is directed at enabling designers of ‘carbon farms’ and ‘food forests’: agroecosystems of perennial plants, to choose the most appropriate plants for their requirements and site conditions. We are working on a subset of plants in the PFAF database identified as having the most potential for inclusion in such designs. We are adding search terms and icons to those plants pages, and providing a range of search options aligned to categories of plants and crop yields, with Help facilities including videos. More >>>

Summary

Sunflowers are usually tall annual or perennial plants that in some species can grow to a height of 3m or more. Perennial sunflowers have protein and oil-rich seeds. Perennial crops are being developed for their oil-seed. The Land Institute see them as part of a perennial polyculture system [1-1].


Physical Characteristics

 icon of manicon of flower

It is hardy to zone (UK) 10.
It is noted for attracting wildlife.
Suitable for: light (sandy), medium (loamy) and heavy (clay) soils, prefers well-drained soil and can grow in nutritionally poor soil. Suitable pH: acid, neutral and basic (alkaline) soils. It cannot grow in the shade. It prefers dry or moist soil.

Edible Uses

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]. Perennial crops are being developed for their oil-seed. The Land Institute see them as part of a perennial polyculture system [1-1].

Medicinal Uses

Various medicinal qualities depending on the species.

Our new book Edible Shrubs is now available.

Edible Shrubs provides detailed information, attractively presented, on over 70 shrub species. They have been selected to provide a mix of different plant sizes and growing conditions. Most provide delicious and nutritious fruit, but many also have edible leaves, seeds, flowers, stems or roots, or they yield edible or useful oil.

Other Uses

See individual species. Some sunflowers are a good source of biomass. The tubers are used in industry to make alcohol etc[141]. The alcohol fermented from the tubers is said to be of better quality than that from sugar beets[269]. Can be grown as a temporary summer screen[200]. Ornamental. A food plants for the larvae of many lepidopterans.

Cultivation details

Management: Standard  Staple Crop: Protein-oil  Under Development

Climate: boreal to warm temperate. Humidity: semi-arid to humid. Carbon Farming Solutions - Cultivation: under development. Management: standard (Describes the non-destructive management systems that are used in cultivation) [1-1]. Perennial crops are being developed for their oil-seed. The Land Institute see them as part of a perennial polyculture system [1-1]. Several perennial sunflowers are being worked with including prairie natives handling boreal to warm temperate semi-arid conditions: Helianthus maximliani (Maximilian sunflower), Helianthus tuberosus (Jerusalem artichoke), Helianthus pauciflorus (Stiff sunflower). Less tolerant of boreal conditions but good on poor soils is Helianthus cusickii ( Cusick's sunflower) [1-1].

Weed Potential

Right plant wrong place. We are currently updating this section. Please note that a plant may be invasive in one area but may not in your area so it’s worth checking.

Perennial sunflower species are not as common in garden use due to their tendency to spread rapidly and become invasive.
