Juniperus ashei (Ashe juniper, post cedar, mountain cedar, or blueberry juniper) is a drought-tolerant evergreen tree, native to northeastern Mexico and the south-central United States north to southern Missouri; the largest areas are in central Texas, where extensive stands occur. It grows up to 10 metres (33 ft) tall, rarely 15 metres (49 ft), and provides erosion control and year-round shade for wildlife and livestock.
