"Heath Balds" in Great Smoky Mountains National Park are dominated by the family Ericaceae. Plants in this family that may be found there include Catawba Rhododendron, Mountain Laurel, Sand Myrtle, Blueberries, Huckleberries, Azaleas and Wintergreen.

Pitcher plants, carnivorous plants which use insects as a source of nitrogen, are also in this order. Pitcher plants are found around bogs, such as those found in the Adirondacks, and other nutrient-poor locations.

As of 2023, 941 species of Ericales have been observed in iNaturalist in the US and 5,086 throughout the world.
