Hypericum olympicum 'Grandiflorum'

Ideal placement of a Hypericum olympicum 'Grandiflorum'

Hypericum olympicum 'Grandiflorum' thrives best in locations with full sun to partial shade. This ensures the plant's bushy and spreading growth habit is well supported, allowing it to reach its full potential of vibrant yellow blossoms throughout the summer months. The species is adaptable to all soil types, provided they are well-drained. Its resilience to drought makes it suitable for a variety of garden settings, particularly in borders, group, or edge plantings, where its silver to grey-green foliage can create a striking contrast. Proper placement ensures this species will flourish with minimal care.

How do I plant a Hypericum olympicum 'Grandiflorum'?

For successful establishment, Hypericum olympicum 'Grandiflorum' should be planted into well-drained soil to accommodate its adaptable nature. This species thrives in both sunny and partially shaded locations. Upon planting, ensure the root ball is level with the soil surface and spaced adequately to allow for its bushy spreading growth habit. Water moderately to settle the soil around the roots and maintain average moisture levels, particularly during dry spells, as the plant is drought-resistant but will benefit from consistent watering while it establishes. Given its moderate growth rate, this plant will reach its mature height of 40 cm, contributing a robust, silvery-green foliage and vibrant yellow blooms to any garden border.

Pruning a Hypericum olympicum 'Grandiflorum'

The minimal pruning requirements of Hypericum olympicum 'Grandiflorum' make it a low-maintenance addition to any garden. To encourage robust growth and maintain its bushy form, it is best to prune in early to mid-spring. This timing allows the plant to recover from any frost damage and capitalize on the burgeoning energy of early season growth. Simply remove any dead or damaged wood and thin out congested areas to allow light and air to reach the center of the plant. This will also help to stimulate the forthcoming blooms.

Watering a Hypericum olympicum 'Grandiflorum'

Hypericum olympicum 'Grandiflorum' has moderate water requirements and is able to withstand periods of dryness due to its drought-resistant nature. However, for optimal growth and bloom, ensure the soil remains moist, particularly during the warm summer months when it is actively flowering. It is important to water deeply and less frequently, rather than light, daily watering to promote a strong, deep root system. In pot culture, be vigilant as the planting medium can dry out faster, requiring more consistent watering to maintain soil moisture.

Fertilising a Hypericum olympicum 'Grandiflorum'

To ensure the robust growth and vibrant yellow blooms of Hypericum olympicum 'Grandiflorum', it is important to provide optimal nourishment through careful fertilization. A balanced, slow-release fertilizer applied once in early spring can support the plant's needs throughout the growing season. The fertilizer should be scattered around the base of the plant, avoiding direct contact with the foliage and stems to prevent any potential damage.

Given its ability to thrive in various soil types, this species does not demand heavy feeding, and over-fertilization should be avoided to maintain its natural growing conditions. An annual application is typically sufficient to sustain its bushy and spreading growth habit, as well as to enhance the silvery aspect of its foliage, which persists from spring through autumn.

The characteristics of a Hypericum olympicum 'Grandiflorum'

Cultivated within the confines of a pot, Hypericum olympicum 'Grandiflorum' offers a compact growth habit, making it an excellent choice for those with limited space. Its vibrant yellow flowers provide a cheerful display throughout the summer months. This variety thrives with minimal care, and its drought-tolerant nature ensures resilience even in less than ideal watering conditions. An often-overlooked benefit is its ability to attract pollinators, adding not only beauty but also ecological value to your garden or patio.
