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 >>>

Parkinsonia microphylla is a spiny, deciduous shrub or a small tree usually growing to 4m. The plant is harvested from the wild for local use as a source of food, and has potential for use as a protein supplement. It is sometimes grown as an ornamental in semi-arid regions[1050]. Also known as Parkinsonia microphylla.

Physical Characteristics

Cercidium microphyllum is a deciduous Tree growing to 4 m (13ft) by 6 m (19ft) at a slow rate.
It is hardy to zone (UK) 9.
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 and can tolerate drought.

Edible Uses

Edible Parts: Flowers  Seed  Seedpod
Edible Uses:

Edible Portion: Seeds, Pods, Flowers. Seeds - cooked[257 , 1333 ]. The dried beans were roasted (often until almost burnt) then ground into a powder and made into a mush or into cakes[257 ]. Usually viewed as a famine food and only used when better foods were not available[257 ]. The seeds are rich in protein (they contain around 22% protein, 50% carbohydrate and 18% fat) and have potential for use as a human food[1543 ]. The dried, powdered seed has a digestibility rating of 76%, increasing to 85% when cooked - this is higher than for many of the commonly eaten legume foods. The seeds do contain antinutritional factors, including trypsin inhibitors, phenols, alkaloids and haemagglutinin, but these are not present in high enough concentration to constitute a major nutritional problem. These antinutritional factors are soluble in saline solutions and can be removed by soaking or during cooking[1543 ]. The seedpods are 35 - 110mm long and 7 - 9mm wide, containing 1 - 4, brown, sub-globose seeds 8 - 10mm long and 5 - 7mm wide[1333 ]. Carbon Farming Solutions - Staple Crop: protein (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].

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

The wood is hard and heavy[1050]. Landscape Use: Xeric and/or native desert gardens as a small multi-branched tree or large background shrub. The Seri people, a Native American group of northwestern Mexico, call this tree ziipxöl; They strung the seeds for necklaces.

Cultivation details

Management: Standard  Staple Crop: Protein  Wild Staple Crop

Climate: subtropical. Humidity: arid to semi-arid. Parkinsonia microphylla is a plant of arid and semi-arid climates in southwestern N. America, experiencing high summer temperatures and a highly variable rainfall[1050 ]. Requires a well-drained soil in a sunny position[1050 ]. The leaves of this species are ephemeral. The plant usually comes into leaf in the rainy season, but the leaves are soon deciduous, the function of photosynthesis being carried out by the green stems[1333 ]. The plant often responds poorly to coppicing[1050 ]. This species occasionally forms hybrids throughout its range with blue paloverde (Parkinsonia florida). In Mexico, it hybridizes with Parkinsonia praecox to form the natural hybrid Sonoran paloverde (Parkinsonia x sonorae)[1050 ]. Although many species within the family Fabaceae have a symbiotic relationship with soil bacteria, this species is said to be devoid of such a relationship and therefore does not fix atmospheric nitrogen[1309 ]. It is slow growing. Trees can live for several hundred years. Carbon Farming Solutions - Cultivation: wild staple. 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  (16+ percent protein, 0-15 percent oil). Annuals include beans, chickpeas, lentils, cowpeas, and pigeon peas. Perennials include perennial beans, nuts, leaf protein concentrates, and edible milks.
  • Wild Staple Crop  Some wild plants have strong historical or contemporary use. Although they are not cultivated crops, they may be wild-managed.
