Pilosocereus pachycladus
(This plant comes in a 3.5" pot. You will receive a very similar plant to the one in the picture. It may or may not be blooming at the time of your purchase. The plant is shipped in its pot to prevent any damage to the roots).
Description: It is one of the most spectacular columnar tree-like cereus 1 to 10 (or more) m tall. It ramify at the base or develops a distinct trunk with dozens of erected glaucous (bluish-silver) branches. Its elegant habit (shape) makes it look like a miniature blue Saguaro. This is one of the bluest columnar cacti.
Pseudocephalium: As Pilosocereus cacti age, they produce what is called a 'pseudocephalium', but in Pilosocereus pachycladus the fertile portion is often slightly differentiated from normal vegetative parts. The floriferous areole are usually located on one or more ribs near the apical part of the branches and produce thick, soft tufts of orange/white hair (sort-of like that seen in 'old man cacti' Cephalocereus senilis). This area of the cactus is where the flowers pop out.
Blooming season (Europe): The flowers open at night in summer and continue the day after; (in its habitat it flowers in October and fruits in January) Flowers are seen only in large, mature specimen at least 1 m tall.
