A solitary, large, drought tolerant, slow growing, monoecious palm. Common in cultivation, locally common in the wild. It has a rough, dark-grey trunk, 12.2 m. (40 ft.) tall, 38 cm. (15 inch) diameter with persistent leaf-bases and spaced ring leaf scars, and huge segmented, pinnate (feather) leaves, 3.7 m. (12 ft.) long, 0.9 m. (3 ft.) wide, bluish-green above and, greyish green beneath.
Butia yatay can tolerate freezing temperatures to about -15°C (5°F). It naturally occurs in open, sun exposed, montane or lowland hilly locations, and should be planted to maximise sunshine exposure. Under extreme freezing conditions we recommend you keep this palm as dry as possible, which will usually mean constructing a glass or plastic roof over the plant to keep rain off. Any cover placed over this palm during times of rain or during cold nights must be removed or vented during hours of sunshine or the plant could be severely heat exhausted.
