Ninfa Study Event - 'a historic landscape in a changing world'

Thursday, 8 Oct 2026, 10:00 am

Via Ninfina II, 68, 04012 Cisterna di Latina LT, Italy

Ninfa IDS Study Event

October 8-9 2026

Giardino di Ninfa

The garden of Ninfa is situated in the ruins of a medieval town and has been described as the most romantic garden in the world, because the combination of ruins, water, history, wild life,  amazing views and inspired planting creates a sensory impact on visitors which is hard to forget. In our study day we will look at the challenges of managing a national monument, as well as the history of planting  through three generations since the garden was formed in the early 20th century, and the challenges of adapting the garden to the 21st century while maintaining its character and ethos. We will also look at Ninfa’s role in Conservation. Our afternoon tour will take in all aspects of the main garden, including the enclosed renaissance garden (hortus conclusus) , and will look at the three arboreta outside the garden, and, if there is time, look round the wetland area (Pantanello) created in the late 20th century.

Notes

Torrecchia  https://www.torrecchia.com/garden

Torrecchia has many connections with Ninfa. In 1991, Prince Carlo Caracciolo and his wife Violante Visconti commissioned the famous architect Gae Aulenti to convert the former 17th-century granary into an elegant and understated villa.

The painter Tullio Pericoli also made his contribution. Located within the castle walls, the jewel of the place is undoubtedly the romantic English garden of about two hectares. It was designed by Lauro Marchetti, curator of the Gardens of Ninfa, and was later developed and maintained by the English landscaper Dan Pearson.

Landriana  https://www.landriana.com/

A true green oasis on the Lazio coastline: the Giardini della Landriana cover over 10 hectares within a large estate, near Tor San Lorenzo in Ardea, 35 km south of Rome.

The peculiarity of the garden lies in its division into ‘rooms’, each of which presents a botanical variety that makes it unique and different from the others, such as the ancient rose valley with its lake; the white avenue; and the olive garden.

It all began in 1956 when Marchese Gallarati Scotti and his wife, Lavinia Taverna, decided to purchase a rural property on the Lazio coast at an auction. They named it La Landriana in homage to one of the names of the Taverna family.

At the time of purchase, the land was completely bare. The couple decided to plant trees to bring some shade to the farmhouse and to mitigate the winds blowing from the sea. Later, a family friend gave Lavinia Taverna a packet of seeds, and the marchioness, almost as a joke, tried to sow them. The result of the experiment was sensational: from those small grains the plants that still make up the Giardini della Landriana were born.

In 1967 they brought in the British landscape architect Russell Page, who divided the large garden into spaces with a strongly geometric design emphasized by hedges and pathways.

Junior IDS Weekend - The Cotswolds

Friday, 16 Oct 2026, 6:00 pm

Cotswolds, UK

Junior IDS Weekend
16th - 18th October 2026


Invitation description

This October, Young IDS heads to the Cotswolds to explore some remarkable tree collections at the most colourful time of the year. Are you joining us?

On Saturday morning, we will visit Tortworth Arboretum, first planted in 1853 and holds an impressive collection of champion trees, including notable specimens of Cedrus deodara, Quercus frainetto and Sequoiadendron giganteum. Collections Manager Jake will introduce us to the collection before we explore the arboretum. We will then continue to Leigh Delamere, where IDS member and former chairman Harriet Tupper will generously welcome us for an afternoon visit to her private tree collection.

On Sunday, we will visit Westonbirt, The National Arboretum, home to one of the finest tree collections in the world and five National Plant Collections (Acer species, Japanese maple cultivars, Tilia, Staphylea and Juglandaceae). Mid-October is a particularly special time to visit, with the maple collection at its colourful best in autumn, including the critically endangered Amami maple. The collection also includes an ancient Tilia cordata coppice, believed to be around 2,000 years old.

A limited number of free beds will be available, we will suggest additional accommodation options nearby, and we will help coordinate shared transport where possible.

Members are welcome to bring a guest (non-member) as long as they can vouch for them.

We look forward to a weekend of remarkable trees, autumn colour and good company!

He has authored his first book, ‘How To Garden When you Rent’ and is a regular panellist on BBC Radio 4’s Gardeners Question Time.
