About the Monument Design
This year, The Monument has been dubbed “RHS x Citi Season of Abundance” to celebrate the energy and abundance of May. Furthermore, this immersive planting installation draws on the symbolism of Beltane, the Celtic festival rooted in folklore which marks the shift from spring to summer.. The design draws inspiration from the vitality and strength of nature at this time of year, incorporating plants with healing properties that reflect the potency of the season. The design uses minimal hard materials, creating a planting-led environment for visitors to move through, with reflective furniture and still water reinforcing the theme of abundance.
The Planting
The selected plants have been chosen for their performance in May and healing properties deeply rooted in folklore and tradition:
- Peonies are long associated with wellbeing, historically used to support circulation, reduce inflammation and encourage calm. They represent both vitality and beauty, making them a powerful presence within the garden.
- Hawthorn (Crataegus) comes into flower around Beltane, marking the shift into late spring. Rich in symbolism, it is linked to renewal, protection, resilience and heart health, embodying both seasonal energy and enduring strength.
- Common elder (Sambucus nigra) reaches a key moment in May, aligning with peak spring growth and seasonal celebrations. A symbol of abundance and vitality, its delicately scented flowers have long been used in traditional remedies, cooking and rituals.
- Lemon balm (Melissa officinalis) is valued for its fresh citrus fragrance and soothing properties. Traditionally used in teas and infusions, it is known to support relaxation, digestion and overall wellbeing, making it a gentle yet uplifting presence in the planting.
- Chamomile (Chamaemelum nobile) brings a softness to the scheme. Celebrated for its calming and anti-inflammatory qualities, it has long been used in herbal preparations to aid relaxation and digestive comfort.

Imogen Perreau is a multi-award winning garden designer based in East Sussex, where the surrounding landscape plays a central role in shaping her work. Inspired by the rolling hills of the South Downs, the changing light and seasons and the meeting of land and sea, her modern country planting style leans towards schemes rich.
Imogen's personal experience of nature’s restorative power underpins her approach and this is seen in her work. The connections found between nature, historical ritual and everyday life continues to inform her designs, bringing a sense of meaning, memory and rootedness to the gardens she creates.
Her path into horticulture grew steadily from a lifelong connection to landscape and the natural world. After spending 15 years working in film and television production, moving back to the countryside brought a renewed appreciation for plants, gardens and the rhythm of seasonal change. What began with growing vegetables at home soon expanded into sowing flowers from seed and developing a deeper understanding of plants, their character, complexity, and the way they bring life, atmosphere and feeling to a space.
Before founding her horticultural creative practice, Imogen built an international career in production, managing creative projects across documentary, music and film. That background in storytelling continues to shape her thoughtful approach to design by creating gardens which feel immersive, deeply rooted in place and resonant with the natural world.
Selected by the RHS, this marks Imogen’s debut at Chelsea Flower Show.
