Description

Hydrangea macrophylla 'Star Gazer', also known as 'Kompeito', is a stunning lacecap hydrangea that stands out with its unique star-shaped blooms. Flowering from early summer to autumn, this reblooming hydrangea produces vibrant, double-florets that appear along both old and new growth, ensuring a continuous display of colour even after colder months. This hydrangea's double star-shaped lace cap flowers, start in hues of soft pink, edged with white, and change based on soil pH — offering a charming mix of hues throughout the season. Reaching a compact height of 120cm (4'), 'Star Gazer' has a neat, mounding habit, making it perfect for borders, containers, or as a specimen plant. Its dark green, coarsely toothed foliage provides a lush backdrop to the delicate blooms. Thriving in partial shade, it does well in areas with morning sun and afternoon protection, making it ideal for gardens with a little less direct sunlight. Whether you’re looking to brighten your garden with stunning colour or add texture and structure, 'Star Gazer' brings elegance and resilience to any space

Planting Conditions

Hydrangeas thrive in moist, well-draining soil with access to sunlight for a good portion of the day, ideally in the morning or filtered sunlight in the afternoon. Planting them in locations with dappled shade or morning sun and afternoon shade helps prevent scorching of leaves and promotes vibrant blooms. Additionally, ensure the soil is rich in organic matter and maintains consistent moisture levels. With these optimal planting conditions, Hydrangeas can flourish, producing abundant and colourful blooms throughout the growing season.

Watering & Feeding

Flower colour varies depending on soil pH: in acidic soils, the blooms mature to a vivid blue, while in neutral conditions, you'll see soft pinks or mauves, with some variation possible in between. For those aiming for the bluest tones, maintaining a pH below 6.5 with a specialist soil additives may be necessary. This hydrangea thrives best in light shade, where it can stay cool and moist, and is ideal for gardeners seeking long-lasting colour and architectural beauty. Hydrangeas benefit from regular watering, especially during dry spells, to keep the soil consistently moist but not waterlogged. We recommend applying water directly to the base of the plant to avoid wetting the foliage, which can lead to fungal diseases. Feeding with a balanced fertiliser in Spring, as new growth emerges, and again in mid-Summer can promote healthy foliage and prolific flowering. Mulching around the base of the plant with organic matter helps retain soil moisture and suppresses weeds, contributing to the overall health and vigour of the Hydrangea.

General Care

Regular deadheading of faded blooms encourages continued flowering throughout the season. Pruning Hydrangeas varies depending on the variety. For most types, prune after flowering, removing spent blooms and any dead or weak stems. Some varieties bloom on old wood, so avoid pruning these in late Summer or Autumn. Hydrangeas are generally disease and pest resistant, but they can occasionally suffer from issues like powdery mildew or aphid infestations. Ensuring good air circulation around the plant and promptly addressing any pest or disease issues helps maintain their health.
