Carthamus tinctorius An important crop for millennia, found in King Tut's tomb. Source of healthful and high-quality oil, which can be made at home using a simple hand-crank press. Trendy as a cut flower. Seeds are an outstanding bird food, which attracts desirable species but not starlings and crows. Petals are used as food coloring, as a replacement for saffron, and as a textile dye. Extremely drought-tolerant, native to dry-summer Mediterranean climates. A good bee and butterfly plant.
With the advent of GMO canola and other GMO oil crops, making pure vegetable oil is now a serious issue for home gardeners and citizens. One piece of good news is that hand-crank, relatively cheap (under $200) and well-made oil presses are now available. The press I am familiar with is the Piteba, imported from Denmark. (Beware the cheap knock-offs)It will press sunflowers, safflower, poppy seeds, camelina, and others (not olives, unless pitted first)
