The round-leaved Hellerkraut grows as a perennial herbaceous plant and reaches heights of 3 to 15 centimeters. It has numerous creeping stems . Usually it forms sterile leaf rosettes and upright flower stems.

The leaves are dark to bluish-green, somewhat fleshy, with entire margins or slightly toothed and glabrous. The round leaves have an aromatic, cress-like taste and chamois like to eat, hence the common name chamois cress.

The hermaphroditic, fragrant flowers are fourfold. Especially when the sun is shining, it gives off a sweet, heavy scent reminiscent of Levkojen . The four free lilac petals are 6 to 9 millimeters long. The anthers are yellow.

The almost wingless pods are 4 to 8 millimeters long and sharply keeled.

The number of chromosomes is 2n = 14.
