On Sunday 20th September 2026, there’s a Rare Plant Fair at Llanover House, Llanover, near Abergavenny, Wales, NP7 9EF. This Rare Plant Fair opens from 11am until 4pm. An historic, listed garden and arboretum. The tumbling Rhyd-y-meirch stream, which runs through the garden, was used by an ancestor of the current owners to create ponds, cascades, rills, and yet another stream, within the 15 acre private grounds. The landscaping trends favoured by Capability Brown were influential, as shown by the Ha-Ha, and clumps of parkland trees, including eight London Plane Trees believed to have been planted in the eighteenth century. Successive generations of the family have continued to plant, particularly Robin Herbert, former President of the RHS, who used his knowledge and passion for trees notable for their autumnal hues, bright berries, or interesting winter bark, to plant throughout the garden. Several of the trees are now National Champions, including a Quercus alba and Nyssa sinensis. The Round garden, planted in 2009 to give ‘maximum effect for minimum effort’ in the autumn, is a feast of colour, shapes and textures in September. The deep herbaceous borders in the unusual circular walled garden, with a dovecote topped by a Pike, have been designed to complement the autumnal hues of gold, red and orange enhancing the berries, barks and falling leaves. I’m told that at least one nursery will be selling orchids and houseplants. For all the details, including information for disabled visitors, please click here.
