Abstract

Utah juniper (Juniperus osteosperma (Torr.) Little [Cupressaceae]) was vegetatively propagated using tip cuttings from juvenile plants. Rooting was most successful (69%) when cuttings were treated with indole butyric acid (IBA) in talc (0.8% ai), struck in 2:1 perlite:peat (v:v) rooting substrate, provided bottom heat, and kept on a mist bench covered by a white polyethylene tent in a greenhouse environment with supplemental lighting. Utah juniper is highly drought tolerant, and superior accessions may have potential for increased use in water-conserving landscapes. The ability to propagate it by vegetative means should facilitate the selection and development of superior plants for use in the landscape industry.
