The Rakai Hebe: Low-Maintenance Evergreen Shrub

T

The Rakai hebe (Hebe rakaiensis), also known as the Shrubby Veronica or Golden Dome Hebe, is a delightful little shrub that brings a touch of year-round beauty to any garden. Native to the South Island of New Zealand, this compact evergreen boasts a dome-shaped form adorned with tiny, glossy green leaves and delicate white flowers.

A Plant with Two Names: Hebe vs Veronica

The Rakai hebe has undergone a recent taxonomic shift. Traditionally classified as Hebe rakaiensis, it’s now recognized as Veronica rakaiensis within the Veronica genus. Both names are widely used, so don’t be surprised to encounter either when researching this plant.

The genus Hebe was previously used for a large group of New Zealand shrubs with similar characteristics to Veronica. However, recent genetic studies revealed a closer relationship between these hebes and other Veronica species. As a result, many hebes, including the Rakai hebe, have been reclassified under Veronica.

A Compact Wonder for Your Garden

One of the most appealing features of the Rakai hebe is its size. Growing to a mature height of just 1-2 feet (30-60 cm) and a spread of 1-3 feet (30-90 cm), it’s a perfect choice for smaller gardens, containers, or edging along flower beds. Its compact form also makes it ideal for rock gardens, where its low profile complements larger rocks and cascading plants.

Year-Round Appeal: From Lush Foliage to Delicate Blooms

The Rakai hebe’s beauty isn’t confined to a single season. Its tiny, bright green leaves maintain their vibrancy throughout the year, adding a touch of evergreen charm to your garden, even during the winter months.

From early to mid-summer, the Rakai hebe comes alive with a profusion of small, white flowers. These delicate blooms are arranged in short, dense spikes, adding a touch of elegance and attracting butterflies and bees to your garden.

Once the flowers fade, the spent blooms can be easily removed to maintain a tidy appearance. However, leaving them on can add a touch of winter interest, especially when frosted with a light snowfall.

Easy Care for the Lifelong Gardener

The Rakai hebe is a gardener’s dream, requiring minimal effort to thrive. Here’s what you need to know to keep your Rakai hebe happy and healthy:

Light: Prefers full sun to partial shade. In hot climates, some afternoon shade is beneficial to prevent scorching of the leaves.

Soil: Adapts well to most well-drained soils, including sandy, loamy, or clay soils. Sand or compost can be added to heavy clay soils to help with drainage.

Watering: To build a robust root system, water frequently during the first growth season. Once established, the Rakai hebe is quite drought tolerant and requires infrequent watering, especially in well-drained soils.

Fertilizer: Not a heavy feeder. Early in the spring, a small dose of a balanced fertilizer may be helpful.

Pruning: Requires minimal pruning. However, light pruning after flowering can help maintain its compact shape and encourage bushier growth.
