Here's a breakdown:

* Full sun: While it can tolerate some sun, full sun exposure can lead to browning and wilting, especially in hotter climates.

* Partial shade: This is the ideal situation for monkey grass. It enjoys dappled sunlight filtering through trees or shrubs.

* Full shade: It can thrive in shady areas, though it may grow slower and less densely.

Important Note: The amount of sun needed can vary slightly depending on the specific variety of monkey grass. Some cultivars, like 'Black Mondo Grass,' are more shade-tolerant than others.

Always refer to the specific care instructions for the variety of monkey grass you have.
