Planting & Growing
Evening Primrose will grow to be about 12 inches tall at maturity, with a spread of 30 inches. When grown in masses or used as a bedding plant, individual plants should be spaced approximately 26 inches apart. Its foliage tends to remain dense right to the ground, not requiring facer plants in front. It grows at a fast rate, and under ideal conditions can be expected to live for approximately 10 years. As an herbaceous perennial, this plant will usually die back to the crown each winter, and will regrow from the base each spring. Be careful not to disturb the crown in late winter when it may not be readily seen!
This plant should only be grown in full sunlight. 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 or pH. It is somewhat tolerant of urban pollution. This species is native to parts of North America. It can be propagated by division.
At Shelmerdine, we treat this plant as a "HOBBY PLANT" meaning that it is not recognized as winter-hardy in our Zone 3 climate. However, there is a possibility that it could survive winter. Regardless of whether it survives a winter or not, this plant is only warrantied until Nov. 1 of its season of purchase.
