What's on at RHS Flower Show Cardiff 2020

Make the most of spring and be inspired to get planting at a show that celebrates horticulture and the great outdoors

RHS LettersCome and join us to celebrate 15 years of RHS Flower Show Cardiff when it kicks off the 2020 gardening season, 17–19 April.

Our celebration will be shared with 15 exhibitors that have had a presence at every show, and will tie in with the Visit Wales theme, the Year of Outdoors. Across the show we are promoting the health and wellbeing benefits of being outside and connecting with the natural world.

From its inception as a pop-up event in 2005, the show has become synonymous with the best of horticulture and Welsh community involvement, supporting ventures from social prescribing and gardening in schools and the wider community to scientific education.

Read on to find out what’s in store and book your tickets ahead of the show.

Spring flowers and plants a-plenty

Visitors in the Floral Marquee
Plants are at the heart of our shows and this year we're making a giant splash with one giant Floral Marquee, housing exquisite blooms. Taking centre stage is the RHS Master Grower for Cardiff – in 2020 the accolade is being awarded to Pheasant Acre Plants from Bridgend. Famous for breeding and selling gladioli and dahlias, Pheasant Acre Plants also supplies plants and bulbs for all seasons.

Of the 44 expert growers, look out for first timers at Cardiff, Glendon Hall Nursery exhibiting a range of delicate epimediums, and Todds Botanics, a family-run nursery in Essex supplying bamboos, olives, hedging, shrubs and perennials. Our RHS Gardening Advice Team can be found here, so gather your gardening queries and ask the experts their advice. Additional nurseries are to be found in the popular Plant Village, providing a burst of floral colour aound the showground.

Garden line-up

This year’s garden line-up includes The Wildlife Trust of South and West Wales, who will walk visitors through what makes a garden wildlife-friendly with their Step into a Wilder Future garden as they build on their successful Wilder Future campaign.
The Giving Nature a Home Partnership (RSPB; Cardiff County Council; Buglife) have teamed up with the Cardiff Rivers Group to create the Taff Bank Garden. By recreating a section of one of Cardiff’s major rivers, the garden will serve as an interactive, educational resource linking to activities at the show aimed at helping people to understand how our actions influence the world around us.
