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
Helianthus hybrids is a PERENNIAL growing to 3.6 m (11ft) by 0.6 m (2ft in) at a fast rate.
See above for USDA hardiness. It is hardy to UK zone 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: mildly acid, neutral and basic (mildly alkaline) soils. It cannot grow in the shade. It prefers dry or moist soil.

Other Uses

Biomass  Oil

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].

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.

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.
