The Royal Horticultural Society of Ireland (RHSI), Ireland’s leading gardening charity, is founded on September 30, 1816.

The RHSI is founded with the purpose of encouraging the love and sharing the knowledge of gardening in all its forms, while fostering environmental awareness and building a sense of community. The inaugural meeting takes place at the Rose Tavern, Donnybrook, Dublin, as the Horticultural Society of Ireland with Francis Caulfeild, 2nd Earl of Charlemont, as its patron and Francis Hetherington as its chairman. The new society holds its first flower show on Easter Monday 1817, and flower and fruit show on August 18, 1817. After a number of shows in the intervening years, the society declines, and is re-established with a new committee in 1830. By 1848, the Society becomes known as the Royal Horticultural Society of Ireland.

The RHSI’s membership is made up of both professional and amateur gardeners from all walks of life who are united by a shared passion for gardens, plants, and growing. The members enjoy access to expert insights through the Society’s printed journal, monthly talks, regular bulletins, and visits to over 60 affiliated Partner Gardens across Ireland and abroad.

The RHSI acts as a central hub, proudly affiliated with horticultural, gardening and floral art societies and clubs across Ireland. These connections help support a nationwide exchange of knowledge, experience, and enthusiasm. From heritage landscapes to urban balconies, the RHSI celebrates the richness of gardening across Ireland. The RHSI remains committed to supporting those who grow, teach, study, and care for plants—helping to ensure that gardening continues to thrive for generations to come.

The RHSI celebrated its 200 anniversary in 2016.

In November 2023, the RHSI announces an extraordinary general meeting to consider changing its name by dropping “Royal” from the title.
