Edinburgh's Historic Palm Houses Reopen After Six-Year Restoration

The iconic Palm Houses at the Royal Botanic Garden Edinburgh have reopened to the public after a six-year restoration project. The historic glasshouses, which had become leaky and rusty, underwent a comprehensive overhaul to preserve their 19th-century architecture and protect a diverse collection of plants.

A Complex Botanical Undertaking

The restoration involved the challenging task of temporarily relocating hundreds of plants, many of which are rare and endangered species. Sadie Barber, the glasshouse curator, described the process as an "unprecedented botanical operation." While the vast majority of plants survived the move and subsequent replanting, one significant casualty was a Sabal palm tree estimated to be over 200 years old. The tree had grown too tall to be moved or stored.

"I think whenever you move a plant and you take it out of the ground and then you stick it in a pot, it's going to suffer or it's going to get under stress," Barber explained. "So there was a bit of trepidation when we picked up the biggest plants, moved them to another place, and left them there for a number of years."

Despite the challenges, Barber expressed delight that the Palm Houses are once again fulfilling their intended purpose. "It feels like a huge achievement getting all these plants back in here and having them actually so well placed," she said. "The glasshouse team have done an enormous job, a really exceptional job of getting the plants looking like they belong. So it's great to see them actually thriving already."

Architectural and Botanical Significance

The restoration work included replacing more than five thousand panes of glass and repairing and repainting the corroding ironwork. Stone elements were also renovated. A partition wall between the two houses was removed to create a more open, airy space that better showcases the architecture and the plants.

Professor Julia Knights, Regius Keeper of the Botanic Garden, highlighted the importance of the collection. "We've got palms, conifers, ferns, begonias, all of those families, plants are hugely important in our living collection and many of them are extinct in the wild," she stated. "So what the palm houses are doing is helping to protect so many of these species, and many of them of course have medicinal properties for human health. So if we don't save these we are also potentially not helping to save humanity, so it's super important."

A New Beginning for an Old Giant

The loss of the ancient Sabal palm was poignant, but its legacy continues. Seedlings were preserved, and one of its descendants has been planted in its place. David Knott, director of horticulture, expressed hope that this younger palm will thrive in the slightly taller glasshouse. "Hopefully, because we've planted it in this glass house which is a bit taller than where it was previously, hopefully it will last a bit longer than the previous one did," he said.

Knott anticipates that the reopening will be welcomed by the public. "For many people in Edinburgh and throughout Scotland and throughout the world, the palm houses in Edinburgh really are one of the most iconic features of the Botanic Garden here," he remarked. "And we hope when we reopen, we will be able to welcome people and they'll be able to enjoy the space as it was always intended to be."

Signs of new life are already apparent within the renovated houses. "You can see new growth coming out of some of those plants that are now in the ground," Barber noted. "When you see that unfurling you know a plant is happy. And if you look around there's just so much life. It's been an enormous job, but a really well done job. So we are overjoyed."

The restoration has modernized the structures with contemporary techniques and materials, ensuring the long-term future of these cherished buildings while maintaining their historic appearance.
