Plant Attributes

The Red Star Hypericum, scientifically known as Hypericum Inodorum 'KOLMAREST', is a perennial flowering plant belonging to the Hypericaceae family. This attractive and versatile plant is known for its beautiful red-tinted foliage and golden yellow flowers, making it a popular choice for gardens and landscape design.

One of the most striking attributes of the Red Star Hypericum is its unique foliage color. The oval-shaped leaves display a vibrant red hue, which deepens in intensity as the plant matures. This reddish tint creates a stunning contrast against the bright yellow flowers, which typically bloom from late spring through summer. Each flower consists of five petals surrounding a cluster of bushy, bright yellow stamens, creating a cheerful and eye-catching display.

The Red Star Hypericum is a low-growing plant, typically reaching a height of 12-18 inches (30-45 cm) and spreading up to 24 inches (60 cm) wide. Its dense, semi-evergreen growth habit makes it an excellent groundcover, and it is particularly effective at suppressing weeds and preventing soil erosion. The plant is also tolerant of a variety of soil types, including sandy, loamy, and clay soils, as long as they are well-draining. It can grow in both full sun and partial shade, making it a versatile choice for many garden settings.

In addition to its visual appeal, the Red Star Hypericum is a low-maintenance plant that requires minimal care once established. It is drought-tolerant, requiring only occasional watering, and can withstand moderate foot traffic. Pruning is generally not necessary, although trimming the plant back in early spring can help maintain its compact shape and encourage fresh growth.

As an added bonus, the Red Star Hypericum is deer-resistant, making it a suitable choice for gardens in areas with high deer populations. Its vibrant color, low-maintenance requirements, and versatility make the Red Star Hypericum a popular plant choice for both novice and experienced gardeners.

Planting & Care

Planting and caring for the Red Star Hypericum is relatively straightforward, making it an excellent choice for both novice and experienced gardeners. Here are some essential planting and care tips to help your Red Star Hypericum thrive:

  1. Plant selection: Choose healthy, well-rooted plants from a reputable nursery. Make sure the plants have vibrant foliage, free from signs of pests or diseases.
  2. Site selection: The Red Star Hypericum can grow in full sun or partial shade. Choose a location that receives at least 4-6 hours of sunlight daily. The plant is adaptable to various soil types, but well-draining soil is essential to prevent root rot.
  3. Planting time: The best time to plant Red Star Hypericum is in the spring or fall, when the weather is mild, and the soil is workable.
  4. Planting process: Dig a hole that is at least twice the width of the plant's root ball and as deep as its container. Gently remove the plant from the container, ensuring not to damage the roots. Place the plant in the hole, making sure the top of the root ball is level with the surrounding soil. Backfill the hole with soil, firming it gently around the roots to eliminate air pockets. Water the plant thoroughly to help settle the soil.
  5. Watering: The Red Star Hypericum is drought-tolerant once established. However, during the first growing season, water the plant regularly to help it develop a robust root system. After the first year, water the plant only during periods of prolonged drought or extreme heat.
  6. Fertilizing: Apply a balanced slow-release fertilizer in early spring to provide essential nutrients and promote healthy growth. Follow the fertilizer manufacturer's instructions for application rates and frequency.
  7. Pruning: Pruning is generally not necessary for the Red Star Hypericum. However, if desired, you can trim the plant back in early spring to maintain its compact shape and encourage fresh growth.
  8. Pest and disease management: The Red Star Hypericum is relatively pest and disease-resistant. However, keep an eye out for common issues such as aphids, spider mites, and fungal diseases. Employ appropriate control measures, such as insecticidal soaps or fungicides, when necessary.
  9. Winter care: In colder climates, the Red Star Hypericum may lose some of its leaves during the winter months. Adding a layer of mulch around the base of the plant can help insulate the roots and protect them from freezing temperatures.
