About us

Since 1989, Interior Green has been delivering high-quality interior landscaping services across Dublin and nationwide, specialising in office plant rental. The company was founded by John Hannigan, a qualified horticulturist who gained valuable experience working with hydroculture systems during his time in Germany.

Over the years, we’ve grown to serve a wide range of clients — from hotels and data centres to multinational corporations and public sector organisations. Our goal is to bring vibrant greenery into workspaces, improving both atmosphere and wellbeing.

We offer a broad selection of tropical plants, imported weekly from the Netherlands, along with an extensive range of stylish planters in terracotta, stainless steel, or durable plastics. Planters can be customised to match your corporate colours and come in various formats — from freestanding and tabletop displays to green walls, room dividers, and custom-built installations.

At Interior Green, we use a hydroculture system — a peat-free method of plant cultivation in water. This sustainable approach reduces the risks of fungal growth, pests, and environmental damage associated with peat harvesting.

Our core service is a rental and maintenance package, which includes regular plant care every two weeks: watering, feeding, pruning, cleaning, and pest management. We also replace plants as needed to keep your displays looking their best.

Alternatively, clients can purchase plants and planters outright, with the option of a separate maintenance agreement.

We’re happy to offer a free consultation and site visit to help you choose the best plants and displays for your space. Interior Green is based in Dublin, Ireland, and provides services nationwide.
