Protecting Edinburgh Botanic Garden from Extreme Weather

The Royal Botanic Garden Edinburgh reopened its historic Victorian palm houses after a five-year, £23.5m restoration project funded by a Scottish Government grant, over £10m from major donors including the National Lottery Heritage Fund, supporters, members, and a £250,000 public appeal.

Restoring the Historic Palm Houses After Five Years

The painstaking refurbishment kept nearly all of the original sandstone and wrought iron shell while installing panels of toughened glass strong enough to resist a bird strike. Inside the reopened building, the air is purified by ferns that naturally remove toxins. Sadie Barber, the glasshouse curator, noted the risk involved in moving large plants to temporary homes for years, but stated, “It feels like a huge achievement getting all these plants back in here and having them actually so well placed.” She added that the glasshouse team did an “exceptional job” and it is “great to see them actually thriving already.”

Protection Against Scottish Winter Storms and Falling Glass

Before the renovation, severe weather presented a constant hazard to the garden’s collections. High gales during Scottish winters frequently sent hundreds of glass panels crashing to the greenhouse floor, leading staff to enforce safety rules that prohibit anyone from entering when winds exceed 30mph. Sadie Barber, the glasshouse curator at the garden, explained that falling glass has previously decapitated plants and allowed icy winter air to rush into tropical spaces, causing severe damage to specimens cared for over decades. In 2026, staff had already been shut out of the greenhouses for 15 days, following a previous year where high winds blocked access for 20 days.

Garden Targets Sixty Five Million Pounds for Second Phase Expansion

Following the reopening of the palm houses, attention turns immediately to a second phase of fundraising requiring an estimated £65 million. Professor Knights stated that the garden hopes to secure a substantial portion of funding from the Scottish Government alongside an imminent public fundraising campaign. This next phase aims to overhaul 1960s research glasshouses that currently house 3,000 precious and endangered plants, construct a plant health hub to quarantine overseas species, and complete a sustainable energy centre utilizing ground source heat pumps. Professor Knights estimates this phase could take around three years.

Community Engagement

The reopening served as the finale of the Garden’s 2026 Creative Programme for communities. Between March and August, five groups—ELREC Polish Group, ELREC New Scots Group, Score Scotland Women’s Group, Headway East Lothian, and Pilton Community Health Project—participated in 21 creative sessions at the Garden.

Community groups from across Edinburgh participated in creative sessions supported by the National Lottery Heritage Fund, culminating in an opening celebration featuring textile banners, ceramic vessels, and a new composition performed by the Botanics Choir.

How do environmental threats impact the living collection?

Director of science Pete Hollingsworth noted that extreme environmental threats in the wild make ex situ safe sites vital for housing rare plant species that have gone extinct in their native habitats.
