Pachycereus weberi is a columnar cactus plant native to Mexico.
Description
[edit]Pachycereus weberi is a columnar cactus that grows strongly tree-like and can reach heights of up to 11 meters. The moderately upright growth habit is candelabra-shaped. However, this typical growth form is only achieved by the plant when it reaches a height of two meters, where numerous branches of the main trunk arise. The slightly waxy, bluish-green side shoots have a diameter of 12 to 20 centimeters and consist of eight to ten ribs, which are covered with white, felty areoles at a distance of 2 to 3 (up to 5) centimeters. The blackish, flattened central spine can be up to 10 centimeters long. It is accompanied by 6 to 12 reddish-brown marginal spines with a length of 2 to 3 centimeters.
The white to yellow flowers, which only open at night, are 8 to 10 centimeters long. The ovary is rounded and woolly. The flower tube is covered with scales and brown hairs. The edible fruits are 6 to 7 centimeters long and have fine yellowish thorns. The flesh is reddish-purple.[2]
