National Botanic Gardens Kilmacurragh, Botanical garden in County Wicklow, Ireland.

National Botanic Gardens Kilmacurragh is a 52-acre garden and arboretum near Wicklow Town, a satellite of the National Botanic Gardens in Glasnevin. Its acidic brown soil, low rainfall and mild winters support rare trees and shrubs, including monkey puzzles, Chilean laurel, tiger-tailed spruce, Wellingtonia, Campbell's magnolia and Mexican cypress. The rhododendron walks were developed with David Moore, curator at Glasnevin, and the gardens hold the national rhododendron collection.

Kilmacurragh began as an Acton family estate in 1712; Thomas Acton II built a Queen Anne style house in 1697 with stone from a dissolved monastery. Thomas Acton IV and his sister Jane Acton created the present gardens from 1854, funding plant-hunting expeditions and using nursery contacts to obtain exotic seeds. A friendship with David Moore, curator at Glasnevin, brought the rhododendron walks and the national rhododendron collection here. The State acquired the neglected gardens in 1976, and their management passed to the National Botanic Gardens in 1996.

The site preserves a Queen Anne style house built in 1697 using stones from a dissolved monastery founded by Saint Mochorog in the 7th century. These stones carry forward a long religious history that continues beneath the present gardens.

The gardens lie 5 km from exit 18 of the M11 motorway, outside Wicklow Town, and are reached by car. A café, Actons, opened in 2015 in one of the restored courtyard buildings. Free guided tours run during the summer months, led by the team restoring and replanting the grounds.

The gardens hold the national rhododendron collection and provide optimal growing conditions for species that cannot thrive in Dublin's Glasnevin gardens. This specialization makes it an essential place for preserving rare plant species.
