There is a final chance to see illustrated prints by Dutch botanical illustrator Pieter van Kouwenhoom, before the exhibition closes next month. The prints are taken from the Royal Horticultural Society's collection, and the species illustrated were grown especially for the C17th garden.
The exhibition, called Garden Flowers by Pieter van Kouwenhoom, runs until 7th July at Forty Hall Estate, Enfield, and admission is free. Directions here and more info here.
There is also an exhibition of contemporary crafts inspired by flowers, called Bud to Bloom, in the Long Gallery at Forty Hall, and the Beauty of Botany exhibition is still running.
More details here about all three exhibitions.
