Its relatively fine texture sets it apart from other landscape plants with less refined foliage. This shrub will require occasional maintenance and upkeep, and is best pruned in late winter once the threat of extreme cold has passed. It has no significant negative characteristics. Hypericum, Red Star is recommended for the following landscape applications; Planting & Growing Hypericum, Red Star will grow to be about 3 feet tall at maturity, with a spread of 30 inches. It tends to fill out right to the ground and therefore doesn't necessarily require facer plants in front. It grows at a medium rate, and under ideal conditions can be expected to live for approximately 5 years. This shrub does best in full sun to partial shade. It does best in average conditions that are neither too wet nor too dry, and is very intolerant of standing water. To help this plant achive its best flowering performance, periodically apply a flower-boosting fertilizer from early spring through into the active growing season. It is not particular as to soil type or pH. It is highly tolerant of urban pollution and will even thrive in inner city environments, and will benefit from being planted in a relatively sheltered location. Consider applying a thick mulch around the root zone in winter to protect it in exposed locations or colder microclimates. This particular variety is an interspecific hybrid. It can be propagated by division; however, as a cultivated variety, be aware that it may be subject to certain restrictions or prohibitions on propagation. Hypericum, Red Star makes a fine choice for the outdoor landscape, but it is also well-suited for use in outdoor pots and containers. With its upright habit of growth, it is best suited for use as a 'thriller' in the 'spiller-thriller-filler' container combination; plant it near the center of the pot, surrounded by smaller plants and those that spill over the edges. It is even sizeable enough that it can be grown alone in a suitable container. Note that when grown in a container, it may not perform exactly as indicated on the tag - this is to be expected. Also note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.
