The Banksian Medal

There is great competition within our Society for the award of this prestigious medal. It is presented each year to the exhibitor who wins the largest total amount of money in prizes in the whole of the horticultural classes at the Show, or who has the highest number of place points within the vegetable, fruit, flower and plant sections. Prizes awarded in Sections 5 to 9 and any other special prizes listed shall not count towards its award. This medal cannot be won by the same competitor more than once in any three-year period. This helps to give different people an opportunity of winning. The medal is granted by the Royal Horticultural Society to affiliated societies.

Sir Joseph Banks was born in 1743 and died a baronet and President of the Royal Society in 1820. He was a very wealthy man and in 1768 he financed and joined Captain Cook’s expedition in the Endeavour. This voyage around the world took him three years. When he reached Australia, Banks and his companions named the coastline where they landed Botany Bay because of the abundance of unknown plants. He returned home laden with dried plants, seeds, roots, illustrations, and records of an astonishing variety of new discoveries.

The Banksian Medal was first issued in 1922 in commemoration of Sir Joseph and “to encourage exhibitions of various garden productions of excellence, merit or novelty “. This tradition has been carried on by the Royal Horticultural Society ever since.
