The survey, which opened online last April, attracted 1,677 votes from Scotland and the UK as well as 37 countries around the world including America, Canada and Australia.
The results reveal that the iconic Scots pine is the number one choice with 15 per cent of the vote. Seen as evocative of Scotland’s landscape, the Scots pine is an important provider of habitat for species such as crossbill, pine marten and capercaillie.
In second place, with 14 per cent of the votes, is the Scottish bluebell or harebell.
The rowan tree is in third place, the Scottish primrose – one of a handful of British flowers that only occur naturally in Scotland – is in fourth place and the silver birch in fifth place.
Votes have also been received for some more unusual choices including bog myrtle, melancholy thistle, Arran whitebeam, round-leaved sundew, twinflower, eyebright and woolly willow.
RBGE’s science conservation officer Dr Heather McHaffie said: "The survey has been fascinating and has also helped provoke discussion about the fragility of our trees and plants. Many of Scotland’s native species are vulnerable or endangered. This can be for a number of reasons from changing land uses or grazing to climate change. From Shetland to the Borders, RBGE is taking a lead to bring at least 75 per cent of threatened native species into its conservation collections."
The survey was inspired by Scotland’s Big 5 campaign to identify Scotland’s favourite wildlife. When Scottish Natural Heritage revealed that its ‘big five’ were animals and birds, RBGE decided to champion biodiversity and find Scotland’s five most popular native trees, plants and shrubs.
Both the SNH and RBGE surveys were part of the Year of Natural Scotland celebrations, championed by VisitScotland.
