The Sawtooth Oak is a species of oak that was imported as an ornamental tree from Asia in 1920. It produces acorns at a relatively young age which makes it a valuable tree for wildlife that feed on the acorns. It is generally considered a low-maintenance tree but may not be reliably hardy during St. Louis winters since it is not very tolerant of freezing weather.
