Description

Commonly called moss rose.  It's rose-like flowers form a moss-like mat, making an excellent ground cover, thus the common name.

The red, orange, yellow, white and other pastel colors come in single, semi-double and double forms.  The flowers do not open on cloudy or rainy days and close up from sundown to sun up.  

This plant has a high drought and heat tolerance.  Aphids and slugs may occasionally be a problem.  Poorly drained soils may lead to crown rot.

Moisture is stored in the leaves and stems

This plant will self-seed, without becoming invasive.  Deadheading will deter self-seeding.  They don't take well to transplanting, care should be given when handling seedlings.

The leaves resemble fleshy spruce needles.
