​The Evolution of an Iconic Garden

Nestled in the heart of Kent, the Delos Garden at Sissinghurst has long been a cherished gem for garden enthusiasts. Between 2019 and 2024, this historic garden underwent transformations that not only revitalized its beauty but also enhanced its ecological and cultural relevance. When we visited in 2019, the Delos Garden looked like a construction site! In May 2023, it had become established despite the coldest January, wettest February and driest March in decades. In 2024, the garden was simply exuberant.

Vision for Renewal
In 2019, the Sissinghurst gardening team Delos Garden embarked on an ambitious project to rejuvenate the garden. They were inspired by the original vision of Vita Sackville-West and Harold Nicolson following an idyllic vacation on that Greek Island. The project aimed to restore the garden's classical charm while increasing biodiversity and incorporating modern sustainability practices.
​

​Staying true to the original design, one of the primary goals was to bring back the historical elements that had faded over time. The team meticulously researched old photographs, drawings, and writings to understand the garden's original layout and plant species. By 2021, many of the historical pathways, ponds, and fragments of Corinthian columns had been faithfully restored, giving visitors a glimpse into the garden's past glory.

Enhancing Biodiversity and Sustainability
To enhance biodiversity, the gardeners introduced a variety of native plant species that were historically present in the region. This not only helped in creating a more resilient ecosystem but also provided a richer tapestry of colors and textures throughout the seasons. By 2022, the garden was flourishing with an array of wildflowers, shrubs, and trees that attracted a diverse range of pollinators and wildlife.

To achieve this on the quarter acre plot, the soil was altered to a planting mix comprising ragstone gravel, crushed brick and poor-quality topsoil. The planting is primarily a palette of Greek natives, suitable for hardiness zone 9.

​Key trees were positioned to optimize light for the garden and the shrubby Mediterranean plants provided evergreen structure. Open areas were left for ephemeral annuals and short-lived perennials, which colonized the gaps and crevices to give the feeling that the ruins have been inhabited by nature.

There are 12 key plants:
Rhodanthemum catananche 'Tizi-n-Test'
Thymbra capitata
Euphorbia rigida
Achillea coarctata
Cotinus coggygria
Tanacetum densum subsp. Amani
Ballota pseudodictamnus
Lomelosia cretica
Sedum sediforme
Lunaria annua 'Corfu Blue'
Origanum laevigatum​

Sustainability became a core focus in the garden's transformation. The team implemented several eco-friendly practices to reduce the garden's carbon footprint and promote environmental stewardship.

A sophisticated rainwater harvesting system was installed to capture and store rainwater for irrigation. This not only reduced the reliance on municipal water supply but also ensured that the plants received clean, chemical-free water. By 2023, the garden had significantly reduced its water usage, even during dry spells.

Chemical fertilizers and pesticides were replaced with organic alternatives. Composting practices were enhanced to create nutrient-rich soil, improving plant health and resilience. The gardeners also used natural pest control methods, such as introducing beneficial insects to keep harmful pests in check. This shift towards organic gardening resulted in healthier plants and a more vibrant garden ecosystem.

​Community Engagement and Education
The transformation of Sissinghurst Delos Garden was not just about physical changes; it also focused on engaging the local community and educating visitors about sustainable gardening practices.

​Future Prospects

As we move into 2025, the future of Sissinghurst Delos Garden looks promising. The ongoing efforts to preserve its historical charm while embracing modern sustainability practices have set a strong foundation for the years to come. It serves as a shining example of how historical gardens can be revitalized to meet contemporary needs while preserving their timeless beauty. The garden continues to be a source of inspiration and tranquility for all who visit, embodying the perfect blend of tradition and innovation. I can’t wait to see it in May and witness its evolution.
