Successful propagation of purple fountain grass from single-internode culm cuttings

In the first article of a two-part series, researchers discuss how propagation daily light integral and root-zone temperature influence root growth and development of single-internode purple fountain grass culm cuttings.

P URPLE fountain [Pennisetum ×advena (formerly known as P. setaceum ‘Rubrum’)] grass is commercially grown and marketed as a horticultural annual in the U.S. and prized for its dark-purple foliage and inflorescences. Production of young purple fountain grass plants or liners is limited because seeds are sterile and most outdoor stock plants are usually lost from killing frosts.
