It is a succulent plant, that has a part of its stem dug-in, and it uses it to retain its supplies, which it will use during the drought periods. The other part of the stem, that sticks out the ground is densely covered with hair. The leaves are silky and often have a reddish central mark. The inflorescence occurs during summer. P. articulatum generates large creamy-white flowers, often with purple streaks on the inside.
