Gash Gardens

📍 Castletown, Laois

🏛️ Attraction

Last updated: 4 March 2026

Overview

Gash Gardens sits on the banks of the River Nore near the village of Castletown, offering a four‑acre sanctuary where water, stone and plant texture intertwine. The garden is a labour of love by dairy farmer Noel Keenan, who in the mid‑1980s began converting his grazing paddock into a horticultural showcase. Today, his daughter Mary and her husband Ross manage the site, welcoming garden lovers, photographers and anyone seeking a quiet day amid thriving flora.

History

The story of Gash Gardens is rooted in a simple vision: to create a place of beauty from ordinary farmland. Over more than 25 years the family has expanded the original paddock into three distinct zones – a semi‑formal gravel garden, a vibrant lawn area with herbaceous borders, and a looped riverside walk. Each zone reflects a commitment to texture and colour, with pathways that reveal new plantings at every turn. The garden’s evolution mirrors the owners’ growing expertise; Ross Doyle now offers landscaping services spanning private gardens to small public spaces, while Mary Keenan shares her knowledge through talks and horticultural consultancy.

What to See & Do

The Moon House

A stone cavern known as the Moon House anchors the garden’s water theme. A cascade tumbles past its circular window into a lily‑filled pond, creating a soothing soundtrack for visitors who pause on the surrounding seats.

Water Features

Beyond the Moon House, meandering streams and still ponds host frogs, newts and reflective surfaces that amplify the garden’s tranquillity. The river walk follows the Nore, offering glimpses of native wildlife and opportunities for quiet contemplation.

Plant Collections

The borders are a riot of texture: rogersia, gunnera, astilbe, ligularia, darmera, iris and crocosmia provide seasonal colour, while standout specimens such as Lilium martagon, Alstroemeria psittacina and Cirsium rivulare ‘Atropurpureum’ draw the eye. A large collection of perennial geraniums pairs with old‑fashioned roses, and shade‑loving plants like Polygonatum, Ypsilandra thibetica, Saruma henryi and Triosteum pinnatifidum add depth to the fernery and woodland areas.

Architectural Highlights

A laburnum archway greets visitors as they enter the fernery, leading to a beech‑hedged path that winds toward the river. Well‑positioned seats and a modest gazebo invite lingering over the views, scents and sounds.

Nursery and Shopping

The on‑site plant nursery offers many of the garden’s own specimens for purchase. Propagated from the garden itself, the plants reflect the owners’ eclectic taste and practical gardening sense, allowing visitors to take a piece of Gash Gardens home.

Events and Learning

Throughout the summer, the garden hosts talks, garden walks and occasional floral art demonstrations. Group tours for ten or more require advance booking, and the owners are happy to arrange private events such as wedding photography, subject to a fee.
