Four O'Clock
The native four-o'clock, also known as showy four-o'clock, is a great plant to add to your dryland garden. This plant is native to about 8000 feet from southern Colorado, across Utah to Mexico.

Before planting the showy four-o'clock, here are some facts to keep in mind. It thrives in full sun and dry soil that drains well. Once established, the native four-o'clock becomes a large, shrub-like plant 18 to 36 inches tall and 36 to 60 inches wide. It can quickly overwhelm smaller plants that have been planted nearby.

The four-o'clock's mass of foliage will die back to the ground in the fall. It reappears late the following spring only after the soil temperature warms. It is a long-lived perennial that blooms from July to September. The four-o'clock has handsome gray-green foliage and showy, rose-pink flowers that are trumpet-shaped and open in late afternoon and evening.
