The body presented the wild Sorbus torminalis trees to mark Kew's 250th anniversary. The trees were planted in the natural areas close to Queen Charlotte's Cottage by tree expert Henry Girling of the Arboricultural Association and Kew's head of arboretum Tony Kirkham.
Girling grew the presentation trees from seed.
"These are modest trees of great beauty," said Girling. "They are medium sized so could be grown in gardens. They have pretty flowers in spring, attractive leaves, wonderful autumn leaf colour and fruits, which the birds like. But these trees are worth growing and conserving in their own right, not just to hang bird boxes in.
"They are also an ancient link to the past. Trees create an important part of the future and we need to look after that future today. We should all give trees as presents, as a matter of principle."
The three wild trees form part of a "chain" of trees that Girling has given as gifts throughout the country over the past 20 years.
