He married again soon after and had at least two sons. The family returned to England in 1650 and returned to Hanmer's ancestral home at Bettisfield. He became closely associated with many leading horticulturalists of the time, and compiled a detailed manuscript under the title The Garden Book of Sir Thomas Hanmer, which was not published until 1933. He specialised in tulips, but also had an interest in cowslips, primroses and anemones. He died in 1678 at Bettisfield.
