John Clayton, a plant collector in Virginia sent him many specimens, as well as manuscript descriptions, in the 1730s. Without Clayton's knowledge, Gronovius used the material in his Flora Virginica (1739–43, 2nd ed. 1762).

He was the son of Jakob Gronovius and grandson of Johann Friedrich Gronovius, both classical scholars. In 1719, he married Margaretha Christina Trigland, who died in 1726, and Johanna Susanna Alensoon in 1729. His son Laurens Theodoor Gronovius (1730–1777) was also a botanist.
