Fun Facts
- 🌱 Wichita Blue is named after Wichita, Kansas, where the Rocky Mountain juniper is native to high elevations, and the 'Wichita Blue' cultivar was selected for its exceptional blue foliage coloration.
- 🌱 Despite their common name, junipers are not true cedars; the blue 'fruits' are actually modified seed cones with fused scales, not botanical berries.
- 🌱 Juniperus scopulorum can live for over 500 years in its native range, making it one of the longest-lived trees in North America, though ornamental cultivars like Wichita Blue may have shorter typical lifespans in cultivation.
