Pretty yellow buttercup flowers are followed by shiny, cherry red berries on this compact, semi-evergreen shrub in late summer and fall; the dazzling fruit is the main attraction, and is perfect for cut flower arrangements; shows rust resistance

Ornamental Features

Magical® Midnight Glow St. John's Wort has masses of beautiful yellow buttercup flowers at the ends of the branches from mid to late spring, which are most effective when planted in groupings. The flowers are excellent for cutting. It features an abundance of magnificent cherry red berries from late summer to mid fall. It has burgundy-variegated forest green foliage. The narrow leaves do not develop any appreciable fall color.

Landscape Attributes

Magical® Midnight Glow St. John's Wort is a multi-stemmed deciduous shrub with an upright spreading habit of growth. 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. Deer don't particularly care for this plant and will usually leave it alone in favor of tastier treats. It has no significant negative characteristics.

Magical® Midnight Glow St. John's Wort is recommended for the following landscape applications;

  • Mass Planting
  • General Garden Use
  • Groundcover
  • Container Planting

Planting & Growing

Magical® Midnight Glow St. John's Wort will grow to be about 3 feet tall at maturity, with a spread of 3 feet. 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 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. 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. 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.

Magical® Midnight Glow St. John's Wort 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.
