Polaskia (named after American amateur Charles Polaski) is a genus of tree-like cacti reaching 4–5 m high, comprising 2 species.

[1][2] The tree-like, highly branched species of the Polaskia genus reach heights of growth of between 4 and 5 meters and form dense crowns 3 to 4 meters above the ground.

Its bright green shoots repeatedly fork and grow 1 to 2 meters long.

On their edges, these wear 3 to 4 millimeters wide, shield-shaped areoles at close intervals.

The red, spherical fruits with a diameter of 2 to 4 centimeters are juicy and edible.
