WebDandelions are important foundation of urban and rural ecosystems, and knowing the sensitivity of their dispersal to the environment helps us predict how the changing climate will impact ecology. This work may also inspire new environmental sensors and actuators in soft robotics or animated materials engineering. WebAppearance. Dandelion has a rosette of basal leaves sprouting from a stout tap root and exudes a milky latex when damaged. The leaves are soft, mid-to-dark green lobed or unlobed with a midrib sometimes pink especially near the base. Flowerheads are mid-yellow, 2.5-5 cm (1-2in) across; the flower stalk pinkish and hollow.
