Western Hairy Rockcress (Arabis hirsuta var. hirsuta) typically prefers moderate sunlight that is neither too direct nor too indirect. For optimal health, the plant should receive full sun in the morning and light shade in the afternoon. Western Hairy Rockcress is best suited for planting in an area that receives at least 4 to 6 hours of sunshine each day. It is also important that it not be planted in an area where it is in deep shade for more than several hours of the day.

This will ensure that the growth of the plant remains robust in the spring and summer months.
