The plant is low-growing, but has thick fleshy roots, and including the extremely short main stem it reaches a total height of 18 cm, with the whole stem 7 cm thick. Branches 3-7, branches of old plants prostrate, 5-7 cm long and 1.2-3 cm in diameter. 3 ribs in a spiral shape, the rib margins strongly zigzagged. The epidermis is blue-green with faint markings. On the rib margins there are wart-like protrusions, 0.5-1 cm long, and each protrusion bears a pair of brown spines 0.3-1 cm long. The tips of new branches have tiny leaves that fall early. Flowers are borne on the rib margins of the middle and upper parts of the branches, yellow-green, very small.

Euphorbia tortirama is a small rare species among Euphorbia, and its spiral ribs are very rare among Euphorbia species. It can be used by botanical gardens for specimen display, and can also be cultivated by some enthusiasts.
It likes warmth and sunlight. The potting mix should be well-drained and have a certain amount of fertility; equal parts of leaf mold, garden soil and coarse sand can be mixed. During the growing period from spring to autumn, it can be watered regularly. In winter keep the potting soil dry; although Euphorbia tortirama can tolerate a low temperature of 3°C, under such low temperatures the epidermis of the stems and branches often turns reddish-brown and shrinks, so it is best to maintain above 10°C and water appropriately.

Cultivation techniques:
Propagation by cuttings: cut branches from the base, dry them for several days, then insert them into a semi-moist medium, keeping warm and semi-shaded conditions; rooting is slow, so be patient and wait for 39.

Euphorbia lactea is leafless, and the markings on its stems are very beautiful, so it can be placed indoors. When propagated in quantity, it can also be used as a rootstock for spherical Euphorbia species.
From late spring to autumn it can be grown outdoors, where it grows more rapidly. In winter maintain the temperature above 5°C. For propagation, stem segments can be cut for cuttings.
This species has a widely cultivated cristate variety, 'Chunfeng'. It grows more rapidly than the original species. And the variegated (white-marked) cristate form, 'Chunfeng Jin', is very rare.
