The following trees are resistant to the oak wilt fungus:
Afghan Pine - A fast growing evergreen tree well adapted to dry, limestone sites.
Bigtooth Maple - Also known as canyon maple. Makes a beautiful ornamental due to its showy autumn color. Ideal for our alkaline soils.
Black Walnut - A large tree common in bottomlands, along streams and in moist upland sites. Leaves look similar to those of pecan. Nuts are round, surrounded by a thick shell that turns black when mature in fall. Does well in landscape settings with ample water.
Chinese Pistache - A fast growing tree with compound leaves that turn red, crimson, and orange in the fall. This tree is resistant to pests and disease, is drought tolerant, and is now widely planted in the Texas Hill Country area.
Italian Stone Pine - Broadly conical when young, then spreading flat-topped and umbrella-like with age. Grows to 25?40'. Picturesque trunk and branch structure with age. Slow to moderate growth. Needles are bright green. Grows well in alkaline soils. Takes drought and heat.
Mimosa (or Silk Tree) - A medium-sized tree used mostly as an ornamental, escaped in localized areas. Tolerant to a variety of sites and to drought and disease.
Western Soapberry - A small to medium sized tree with large leaves comprised of many leaflets that turn yellow in the fall. The white flowers grow in large clusters and develop into berries.
