When grown in masses or used as a bedding plant, individual plants should be spaced approximately 8 inches apart. It grows at a fast rate, and under ideal conditions can be expected to live for approximately 3 years.
This plant does best in full sun to partial shade. It prefers dry to average moisture levels with very well-drained soil, and will often die in standing water. It is considered to be drought-tolerant, and thus makes an ideal choice for a low-water garden or xeriscape application. It is not particular as to soil type, but has a definite preference for alkaline soils. It is somewhat tolerant of urban pollution. This is a selected variety of a species not originally from North America.
