Carthamus tinctorius is apparently native originally to the eastern Mediterranean; it is known only in cultivation and as escapes today. Safflower has been reported from Texas; I have not seen the specimen.

Safflower is cultivated as an oil seed, a source of vegetable dye, as birdseed, and as an ornamental. It is one of the earliest known crop plants, with cultivation dating back to prehistoric times. In the United States safflower is grown principally in California and Arizona; it has been a successful crop in every state west of the 100th meridian.

Carthamus oxyacantha M. Bieberstein (wild safflower) was collected in 1978 in Monterey County, California. It is considered by the United States Department of Food and Agriculture to be a noxious weed subject to eradication if found. In central and southern Asia it is a pernicious weed of agricultural lands and other disturbed ground. Carthamus oxyacantha most closely resembles cultivated safflower; it has smaller heads and much spinier leaves. Its cypselae are usually darkly pigmented, smaller (4–5 mm versus 5.5–9 mm), and almost always lack pappi.

Carthamus tinctorius
Worldwide safflower production
Carthamus tinctorius - MHNT

Safflower (Carthamus tinctorius) is a highly branched, herbaceous, thistle-like annual plant in the family Asteraceae. It is commercially cultivated for vegetable oil extracted from the seeds and was used by the early Spanish colonies along the Rio Grande as a substitute for saffron.[2] Plants are 30 to 150 cm (12 to 59 in) tall with globular flower heads having yellow, orange, or red flowers. Each branch will usually have from one to five flower heads containing 15 to 20 seeds per head. Safflower is native to arid environments having seasonal rain. It grows a deep taproot which enables it to thrive in such environments.

Biology

Plant morphology

Safflower is a fast growing, erect, winter/spring-growing annual herb, that resembles a thistle.[3] Originating from a leaf rosette emerges a branched central stem (also referred to as terminal stem), when day length and temperature increase. The main shoot reaches heights of 30–150 cm (12–59 in). The plant also develops a strong taproot, growing as deep as 2 m (6 ft 7 in). First lateral branches develop, once the main stem is about 20–40 cm (7.9–15.7 in) high. These lateral branches can then branch again to produce secondary and tertiary branches. The chosen variety as well as growing conditions influence the extent of branching.

The elongated and serrated leaves reach lengths of 10–15 cm (3.9–5.9 in) and widths of 2.5–5 cm (0.98–1.97 in) and run down the stem. The upper leaves that form the bracts are usually short, stiff and ovate, terminating in a spine.[3] Buds are borne on the ends of branches, and each composite flower head (capitulum) contains 20–180 individual florets. Depending on variety, crop management and growing conditions, each plant can develop 3–50 or more flower heads of 1.25–4 cm (0.49–1.57 in) diameter. Flowering commences with terminal flower heads (central stem), followed sequentially by primary, secondary and sometimes tertiary branch flower heads. Individual florets usually flower for 3–4 days. Commercial varieties are largely self-pollinated. Flowers are commonly yellow, orange and red, but white and cream coloured forms exist.[3] The dicarpelled, epigynous ovary forms the ovule. The safflower plant then produces achenes. Each flower head commonly contains 15–50 seeds; however, the number can exceed 100. The shell content of the seeds varies between 30 and 60%, the oil content of the seeds varies between 20 and 40%.[3]

Plant development

Safflower usually emerges 1–3 weeks after sowing and grows slower under low temperatures. Germination of safflower is epigeal. The first true leaves emerging form a rosette. This stage occurs in winter with short daylength and cold temperature, as the safflower can tolerate frosts up to −7 °C (19 °F) during the rosette stage.

When temperature and daylength start to increase, the central stem begins to elongate and branch, growing more rapidly. Early sowing allows more time for developing a large rosette and more extensive branching, which results in a higher yield.

Flowering is mainly influenced by daylength. The period from the end of flowering to maturity is usually 4 weeks. The total period from sowing to harvest maturity varies with variety, location, sowing time and growing conditions; for June or July sowings, it may be about 26–31 weeks.[3]

Both wild and cultivated forms have a diploid set of 2n = 24 chromosomes. Crossings with Carthamus palaestinus, Carthamus oxyacanthus and Carthamus persicus can produce fertile offspring.

History

Safflower is one of humanity's oldest crops. It was first cultivated in Mesopotamia, with archaeological traces possibly dating as early as 2500 BC.[4]

Chemical analysis of ancient Egyptian textiles dated to the Twelfth Dynasty (1991–1802 BC) identified dyes made from safflower, and garlands made from safflowers were found in the tomb of the pharaoh Tutankhamun.[5] John Chadwick reports that the Greek name for safflower (kārthamos, κάρθαμος) occurs many times in Linear B tablets, distinguished into two kinds: a white safflower (ka-na-ko re-u-ka, knākos leukā, κνάκος λευκά), which was measured, and red (ka-na-ko e-ru-ta-ra, knākos eruthrā, κνάκος ερυθρά) which was weighed. "The explanation is that there are two parts of the plant which can be used; the pale seeds and the red florets."[6]

The early Spanish colonies along the Rio Grande in New Mexico used safflower as a substitute for saffron in traditional recipes. An heirloom variety originating in Corrales, New Mexico, called "Corrales Azafran", is still cultivated and used as a saffron substitute in New Mexican cuisine.[2]

Cultivation

Climate

Safflower prefers high temperatures and grows best at 28–35 °C (82–95 °F). It tolerates 40 °C (104 °F), but there are also some varieties which grow under very low temperatures.[7] Safflower is cultivated in different seasons: as a winter crop in south central India, as an early summer crop in California and as a mid-summer crop in the Northern Great Plains of the United States.[8] Minimum length of the growing season is 120 and 200 days for summer and winter cultivars, respectively.[9] Plant performance is highly dependent on the different planting dates in terms of temperature and day length.[8] Winter hard varieties only form a rosette in late fall and elongates in spring.[8] In early stages, safflower tolerates humidity but after bud stage the danger of a Botrytis blight infestation increases[8]

Safflower is drought tolerant.[10] The tap root makes moisture from deep soil layers available.[8] Additionally, this tolerance can also be explained by the higher water use efficiency compared to other oil crops such as linseed and mustard.[11] Shortly before and during maximum flowering water requirements are the highest.[8] Beside drought tolerance, all parts of the plant are sensitive to moisture in terms of diseases.[8] In the case of excessive water supply, it is susceptible to root rot.[8] Therefore, many varieties are not suitable in irrigated agriculture especially on soils with danger of waterlogging.[9]

Safflower tolerates wind and hail better than cereals.[12] It stays erect and can retain the seeds in the head.[8]

Soil

Safflower prefers well-drained, neutral, fertile and deep soils.[8][7] It can adapt well to soil pH (pH 5–8) and tolerates salinity.[7] Safflower can be well grown on different soil types, with water supply as its main driving factor for suitability, depending on climate and irrigation, and the resulting different water regimes of the different soil types.[8] Therefore, cultivation on shallow soils and especially on soils with danger of waterlogging is not suitable.[9] The deep rooting promotes water and air movement and improves the soil quality for subsequent crops in a rotation.[12]

Nutrient requirements can be compared to wheat and barley, except nitrogen amendment should be increased by 20%.[8] Therefore, soils with an adequate nitrogen supply are favorable.[9]

Agricultural practice

Crop rotation and sowing

Safflower is frequently grown in crop rotation with small grains, fallow and annual legumes.[13] Close rotation with crops susceptible to Sclerotinia sclerotiorum should be avoided (e.g. sunflower, canola, mustard plant and pea). A four-year rotation is recommended to reduce disease pressure.[13]

Seeds should be sown in spring as early as 4.5 °C (40.1 °F) soil temperature is exceeded, to take advantage of the full growing season. If wireworms were a problem in the field in previous seasons, a respective seed treatment is recommended. A planting depth between 2.5–3.5 cm (0.98–1.38 in) is optimal. Shallow seeding promotes uniform emergence resulting in a better stand.

Seeding rate recommendations are around 17–33.5 kg/ha (15.2–29.9 lb/acre) of live seed.[13] Where lower seeding rates promote branching, a longer flowering period and later maturity and higher rates promote thicker stands with a higher disease incidence. Sufficient moisture is necessary for germination. Usually, row spacing between 15–25 cm (5.9–9.8 in) are chosen using similar drill settings as recommended for barley.[13]

Management

The total N recommendation is 90 kg/ha (80 lb/acre). This should include credits based on previous crops and soil available N. For the latter, deeper positioned nutrients need to be taken into account as safflower will root deeper than small grains and therefore access nutrients unavailable to them.[13] Safflower growing in soils low in phosphorus need to be fertilized. Up to 39 kg/ha (35 lb/acre) of phosphate can be drill-applied safely.

A weed control program is essential when growing safflower as it is a poor competitor with weeds during the rosette stage.[13] Cultivation on fields with heavy infestation of perennial weeds is not recommended.

Harvest

Safflower is mature when most leaves have turned brown approximately 30 days after flowering.[13] Seeds should fall from the head when rubbed. Rain and high humidity after maturity may cause the seeds to sprout on the head.[13]

Harvesting is usually done using a small-grain combine harvester.[13] Moisture in seeds should not exceed 8% to allow for a safe, long-term storage. Drying can be done similar to sunflower. Temperatures must not exceed 43 °C (109 °F) to prevent damage to the seed and ensure quality.

Pests

Diseases

Alternaria spp. present one of the most prevalent diseases causing losses as high as 50% in India.[14] In a field trial in Switzerland, Botrytis cinerea was the most prevalent disease.[15]

Production

In 2020, global production of safflower seeds was 653,030 tonnes, led by Kazakhstan with 35% of the world total (table). Other significant producers were Russia and Mexico, with 28% of world production combined.

Uses

Traditionally, the crop was grown for its seeds, and used for coloring and flavoring foods, in medicines, and making red (carthamin) and yellow dyes, especially before cheaper aniline dyes became available.[5]

Safflower oil

For the last fifty years or so, the plant has been cultivated mainly for the vegetable oil extracted from its seeds. Safflower seed oil is flavorless and colorless. It is used mainly in cosmetics and as a cooking oil, in salad dressing, and for the production of margarine. INCI nomenclature is Carthamus tinctorius.

There are two types of safflower that produce different kinds of oil: one high in monounsaturated fatty acid (oleic acid) and the other high in polyunsaturated fatty acid (linoleic acid). Currently the predominant edible oil market is for the former, which is lower in saturated fats than olive oil. The latter is used in painting in the place of linseed oil, particularly with white paints, as it does not have the yellow tint which linseed oil possesses.

In one review of small clinical trials, safflower oil consumption reduced blood low-density lipoprotein levels – a risk factor for cardiovascular diseases – more than those seen from butter or lard consumption.[18]

Flowers for human consumption

Safflower at a market

Safflower flowers are occasionally used in cooking as a cheaper substitute for saffron, sometimes referred to as "bastard saffron".[25]

The dried safflower petals are also used as a herbal tea variety.

Dye from flowers

Safflower oil as a medium for oil colours

Safflower petals contain one red and two yellow dyes. In coloring textiles, dried safflower flowers are used as a natural dye source for the orange-red pigment carthamin. Carthamin is also known, in the dye industry, as Carthamus Red or Natural Red 26.[26] Yellow dye from safflower is known as Carthamus yellow or Natural Yellow 5.[27] One of the yellow pigments is fugitive and will wash away in cold water. The dye is suitable for cotton, which takes up the red dye, and silk, which takes up the yellow and red color yielding orange. No mordant is required.[28]

In Japan, dyers have long utilised a technique of producing a bright red to orange-red dye (known as carthamin) from the dried florets of safflower (Carthamus tinctorius). Darker shades are achieved by repeating the dyeing process several times, having the fabric dry, and redyed. Due to the expensive nature of the dye, safflower dye was sometimes diluted with other dyestuffs, such as turmeric and sappan.[29]: 1 

Biodegradable oil

In Australia in 2005, CSIRO and Grains Research and Development Corporation launched the Crop Biofactories initiative to produce 93% oleic oil for use as a biodegradable oil for lubricants, hydraulic fluids, and transformer oils, and as a feedstock for biopolymers and surfactants.[30]
