Safflower plants in bloom. The flowers from the safflower plant (Carthamus tinctorius) can be used to make dye, but the plant is mainly grown for the oil in its seeds (20-38% content). In favourable conditions, the crop can be harvested after 120 days of growth. The seed oil is used mainly in paints and varnish, although it can also be used as a cooking oil and to make soap. After the oil has been extracted, the seed residue can be used as animal fodder because of its high protein content. Photographed in California, USA.
