The Rigid Stacheldolde is a perennial plant that becomes 20 to 80 centimeters high and which has a gray-green, hemispherical-bush-like appearance. The firm, knotty and downy to bare stems are hollow and stripy to ribbed.
Their stalked leaves, with leaf sheaths , are 2–3-fold pinnate, they are fleshy and stiff with thorny, keeled on the underside, runny sections on the top. The terminal or axillary, double flower umbels consist of 4–8 or more finely haired, thick rays and a 5–10-leaved, spiky sheath. The flowers are five-fold with a double flower envelope . The petals are white, rarely pink. The small sepals are spiky. Each döldchen, with a spiky sheath, contains a central hermaphrodite flower, surrounded by a few male flowers whose stems are connected to the ovary or the flower cup and form a shell around the fruit. The plants are Andromonöz . The ovary is subordinate with long stylus branches and a small stylus pad.
The weak rippige fruit ( false fruit ) is topped by the woody and pointed calyx lobes and the stylus branches. A carpophore is missing here .
The flowering period is June to October.
