Description
Echinopsis lageniformis, also known as Trichocereus bridgesii, is a fast-growing columnar cactus with greenish to bluish stems that usually have 4 to 8 ribs. The stems grow up to 16.4 feet (5 m) tall and up to 8 inches (20 cm) in diameter. The spines are up to 2.8 inches (7 cm) long and range in color from honey-colored to brown. They are located on the nodes in groups of up to 4. The large flowers are white and up to 5.2 inches (18 cm) long.

How to Grow and Care
If you can grow cacti and succulents successfully, you can likely grow the Echinopsis species without too much trouble. Like many cacti, they prefer a drying period between waterings, even to the point where they slightly wilt. When you water, however, you should water deeply. The plant will noticeably plump up. The cactus mustn't be exposed to prolonged dampness and sitting water. Never let your cactus sit in a dish of water. Lastly, fertilize during the growing season for the best results.
Echinopsis can be easily rooted from offsets, which tend to cluster around the base of the mother plant. Cut offsets close to the stem, at the narrowest possible place. When rooting cacti from cuttings, let the fresh cutting dry out slightly on a paper towel and cut the cacti at the narrowest place possible. After a few days to a few weeks, depending on the size of the cut surface, the cut surface should have dried out and formed a callous or slightly rough opening. Once the callous has formed, place the cutting in a rooting mixture of fast-draining cacti soil.
