good locations

Potential living space locations include a South window, or a three to four seasons room that receives plenty of sun light. This species will tolerate very cool days and cold nights, but will need the temperatures to remain above 20 °F. It is possible for this variety to survive freezing temperatures, but cold exposure will cause skin damage. It is an option to over winter this plant in almost any low light window space as long as it is set outdoors for more sun in the growing season. If this variety is to be set outdoors during the growing season it needs to be in a location with plenty of sun and will tolerate lots of rain.

These plants may start with 5 ribs as small plants and increase these ribs to 8 ribs, but sometimes plants may continue to increase the number of ribs as they grow depending on the individual plant genetics.

Flowers can be up to 3 inches wide on large adult plants and they are almost always bright yellow.


Ornatum is a cactus that grows from 4 to 12 inches wide, and may become columnar with age. They remain in a globular form for many years, and if they do become columnar they can get up to 4 feet high. These plants have a common name, 'Monk's Hood', but whatever... They sport fairly thick spines along their ribs and vary in the amount of, what's called, fleck or frocking. Individual plants can vary in appearance with different frocking patterns, which gives a lot of variety to the visual appearance of ornatum.
