Apple Cactus, Column Cactus, Peruvian Apple, Peruvian Apple Cactus: Cereus peruvianus (Cereus uruguayanus)
This columnar cactus has a bluish-green, ribbed column and stout, brown spines. Eventually, it produces large, scented, white, funnel-shaped flowers, 2–3in (5–7.5cm) wide. Cereus peruvianus monstrosus, sometimes listed as Cereus ‘Monstrosus’ (pictured), is an unusual form that is much smaller than the species and has attractively distorted, branched stems with irregular ribs.
