Pilosella aurantiaca aka Orange Hawkweed

Pilosella aurantiaca, also known as fox-and-cubs, orange hawk bit, devil's paintbrush, or grim-the-collier, is a perennial flowering plant in the Asteraceae family. Native to alpine regions of central and southern Europe, this low-growing plant has shallow fibrous roots and a basal rosette of elliptical to lanceolate leaves that exude a milky juice. The stem and leaves are covered with short stiff hairs, usually blackish in color. The stems may reach a height of 60 centimeters and have 2-25 capitula (flowerheads), each 1-2+1⁄2 cm in diameter, bundled together at the end of short pedicels. The flowers are orange, almost red, and reflect ultraviolet light, making them conspicuous to pollinators. The flowers are visited by various insects, including many species of bees, butterflies, and pollinating flies. While orange hawkweed is invasive in North America and Australia, it is also a rare houseplant that needs regular watering and direct light to thrive. It prefers soil that is well-draining and does not require added fertilizers if repotted each time it doubles in size.
