Plant Importation
With the Age of Exploration
came a keen interest in
Botany. Plants were brought
To Europe from all over the

and private collectors vied
with each other for the largest and
most exotic collections.

and by the 1890’s, the trade had grown to 2,000 tons. In 1875,
50 tons of vines were imported from the US.
