Held at the Horticultural Halls in Westminster, the events will bring together the society’s annual Orchid Show with a display of paintings and drawings of plants.
Works by more than 25 artists from as far a field as Japan, Australia and Taiwan will be shown alongside the RHS’ commissioned works of award winning orchids.
The RHS Lindley Library has a collection of more than 7,000 drawings depicting award winning orchids.
A display of 20 gold medal winning contemporary works will also be on show.
RHS international orchid registrar Julian Shaw said: "Orchids are currently the most popular pot plants. Current biotechnology enables millions of clones to be produced rapidly from a first class plant, and make them available affordably through retail outlets. In the last two decades, Orchids have gone from being a class symbol to global pot plant market leader, only rivalled by Poinsettias at Christmas time."
Last December the RHS registered over 500 new orchid hybrids from around the world.
The show will also feature a series of talks aimed at all levels with further displays from the National Association of Flower Arrangement Societies.
