Origin and Common Names
Euphorbia atrox S.Carter, commonly known as the big thicket spurge or cactus spurge, is a species of flowering plant in the Euphorbia genus. It is native to southern and central Texas, as well as to northeastern Mexico.
Appearance
The big thicket spurge is a perennial plant that grows up to three feet tall. The stems are thick, woody, and branched, with a gray-green color. The plant has spines along the branches, which are modified leaves, giving it a cactus-like appearance. The leaves are small and fall off early in the plant's growth. The flowers are small, yellow-green, and grouped into clusters, called cyathia, which are surrounded by a cup-like structure called an involucre.
Uses

Propagation of Euphorbia atrox S.Carter
Euphorbia atrox S.Carter, commonly known as Candelilla, is a succulent perennial plant that is native to the Chihuahuan Desert of Mexico and the southwestern United States. This plant has a unique appearance and is characterized by its green or grayish stems that resemble sticks or candles.
Propagation by seeds
One method of propagating Euphorbia atrox S.Carter is through seeds. Collect the seeds from the plant's capsules during the fall and winter seasons and sow them in a pot filled with well-draining soil mix. Keep the soil moist but not waterlogged and place the pot in a warm, bright area. The seeds should germinate within one to two weeks, and once the seedlings have grown large enough, they can be transplanted into individual pots.
Propagation by stem cuttings
Euphorbia atrox S.Carter can also be propagated by stem cuttings. Cut a stem with a clean, sharp knife from the parent plant, making sure to include two to three nodes. Allow the cutting to dry and callus over for about a week before planting it in a pot filled with well-draining soil mix. Water the cutting sparingly and keep it in a warm, bright area. The cutting should root in 2 to 4 weeks, and once established, can be transplanted into individual pots.
Propagation by offsets
Euphorbia atrox S.Carter also produces offsets or baby plants that spring from the base of the parent plant. These offsets can be removed and planted in individual pots using a well-draining soil mix. The soil should be kept moist but not waterlogged, and the plant should be placed in a warm, bright area until it has established roots and new growth.
Propagation of Euphorbia atrox S.Carter is relatively easy, and the plant is an excellent addition to any garden or collection of succulent plants.
