Scrub Oak plays a vital role in supporting biodiversity by attracting birds and a diverse range of butterflies. Its ability to thrive in various conditions and benefits to local wildlife make it a valuable addition to gardens.

It is a medium-to-small oak. Its green leaves are leathery on the surface and somewhat hairy on the underside. Scrub Oak is a versatile plant that thrives in full sun to part shade. In cooler regions, it remains compact, while in warmer areas, it spreads out and grows several meters high.

Scrub Oak benefits from a thick layer of oak leaves as mulch with a few large rocks. Refrain from summer watering to mimic its natural drought-tolerant adaptation.
