True porcelain was first made at Derby in 1748 under the direction of the modeller Andrew Planché and much of the early production clearly mimicked Chelsea products. By 1770, the owners of Derby would actually purchase the Chelsea factory. Like Chelsea, Derby would produce work with botanical illustrations. This diamond shaped plate was painted by William Pegg. Pegg was known as the greatest of all the botanical illustrators and worked not from prints or engravings, but from life.
