The Beauty of Botany.
An exhibition of 17th and 19th century botanical drawings and watercolours from the Royal Botanic Gardens at Kew is underway. Held at Forty Hall Estate, Enfield, the exhibition is called 'The Beauty of Botany' and runs until 7th July. Admission is free. Directions here and more info here.
The organisers are confident that these drawings and watercolours can help "deepen your understanding of plant anatomy and the visual qualities of flowers". They are hung along the Grand Staircase at the heart of Forty Hall, a Jacobean mansion situated in extensive gardens and parkland, which offers education activities and exhibitions. More details here.
