Broomrape (Cistanche tubulosa) is a flowering plant that grows in arid areas in Israel – I’ve seen them in the Large Makhtesh, Judean desert and while hiking the Israel trail north of Eilat. They are recognizable by a 30cm spike of densely packed yellow flowers. When they are not flowering, no part of the plant is visible above ground. There are no leaves, in fact, the plant contains no chlorophyll and so cannot do photosynthesis. The broomrape is a parasitic plant, one that derives some or all of its sustenance from another plant. Parasitic plants have a modified root, the haustorium, that penetrates the host plant. Amazingly about 4100 species in about 19 families of flowering plants like this are known. On my tours, I always try to point out some interesting flower, plant or tree.
