Pinesap Flowering

8-5-13 pinesap3  125Pinesap (Monotropa hypopitys), like its close relative Indian Pipe, is a flowering plant which has no chlorophyll, and therefore is not green. Often found under pine trees, Pinesap’s color ranges from yellow to pink, red, orange or brown or some combination of these. Because it has no chlorophyll, it also cannot obtain energy from sunlight. (Therefore, it can thrive in very shady areas.) Pinesap gets its nutrients from other plants’ roots, but not directly. Mycorrhizal fungi are the middlemen, connecting the roots of Pinesap with those of its host plant, allowing nutrients to be passed along from the host plant to the Pinesap. This fungi-dependent relationship is called mycotropism. Similar to Indian Pipe, during fruiting Pinesap’s previously-nodding stem straightens, becoming erect.
