It has threadlike stems that can measure up to 2 meters in length, starting from a tuberous stump that measures between 1 and 5 cm in diameter. The stems have bulbils near each pair of leaves, which allows them to take root if the stem breaks. The leaves are fleshy, heart-shaped (hence its vernacular name "chain of hearts"), mottled with silver on the top and reddish on the reverse. The more it is exposed to the sun, the more the plant takes on a purple color. Its flowers are particularly remarkable but discreet (1 to 1.5 cm in height): of a pink color, they have a bulge at the base and are tinged with black on the top.
