His estate Hartekamp had a rich variety of plants and he engaged the Swedish naturalist Carl von Linné, who stayed at his estate from 1736 to 1738, to write Hortus Cliffortianus (1737), a masterpiece of early botanical literature published in 1738, and for which Georg Dionysius Ehret did the illustrations. Many specimens from Clifford’s garden were also studied by Linnaeus for his Species Plantarum (1753).
