Planting & Growing
Miller's Crimson Primrose will grow to be about 8 inches tall at maturity extending to 18 inches tall with the flowers, with a spread of 9 inches. When grown in masses or used as a bedding plant, individual plants should be spaced approximately 7 inches apart. Its foliage tends to remain low and dense right to the ground. It grows at a fast rate, and under ideal conditions can be expected to live for approximately 5 years.
This plant does best in partial shade to shade. It requires an evenly moist well-drained soil for optimal growth, but will die in standing water. It is not particular as to soil type or pH. It is somewhat tolerant of urban pollution, and will benefit from being planted in a relatively sheltered location. Consider applying a thick mulch around the root zone in both summer and winter to conserve soil moisture and protect it in exposed locations or colder microclimates. This is a selected variety of a species not originally from North America.
Miller's Crimson Primrose is a fine choice for the garden, but it is also a good selection for planting in outdoor pots and containers. It is often used as a 'filler' in the 'spiller-thriller-filler' container combination, providing a mass of flowers against which the larger thriller plants stand out. Note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden. Be aware that in our climate, most plants cannot be expected to survive the winter if left in containers outdoors, and this plant is no exception.
