Upcoming Events

The Events Committee of the RHSI organise a full and varied programme of events for members and guests. Some events must be pre-booked. Early booking is advisable and bookings are taken on a first come first served basis.


Lectures take place on Wednesday evenings and during the winter months, on Saturdays afternoons. There is a fantastic range of prominent speakers from gardeners to designers and plant specialists from Ireland and abroad who share a wealth of experience and photographs.

Floral Art demonstrations also take place on Wednesday evenings. We have many well known floral artists from Ireland and occasionally from abroad who come and show us new and innovative ways of creating flower arrangements. Gala demonstrations organised at Christmas are always a sell-out and early booking is advisable.

Day tours are organised during the summer months and are extremely popular. The tours consist of visits to gardens of which many are not usually open to the general public, as well as visits to other well known gardens. Travel is by coach leaving from south Dublin but with the option to meet the coach along the route for country members is required.

Overnight tours in Ireland and abroad are arranged each year. These are also very popular and can be booked up very quickly.

All events are listed on the programme. At times a last minute opportunity for a special garden visit or lecture may arise and these are posted on the website and sent to members by email as soon as they become available.

Lectures and floral art demonstrations are usually held in Wesley House, Leeson Park, Dublin 4. Some lectures and seminars are held in the National Botanic Gardens, Glasnevin. Full details are listed under each event.

Non members are very welcome to join our events many of which must be pre-booked. Occasionally events will be restricted to members only.
