To address issues of invasiveness with some Buddleja L. species, a triploid Buddleja was released. Buddleja (Scrophulariaceae Juss., formally Buddlejaceae K. Wilhelm and Loganiaceae R. Brown), commonly called butterfly bush, is a recent addition to invasive plant lists in the United States but has been on invasive lists in other countries for a longer period of time (Crawley, 1987; Oregon Department of Agriculture, 2006; Staples et al., 2000). Buddleja davidii Franch., the most commonly used species in landscape plantings, is singled out on these lists because of its ability to grow in most environments, outcompete native plants, and to produce hundreds to thousands, and even millions, of seeds per year. The seeds that dehisce from capsules are small, lightweight, and typically winged, allowing them to disseminate freely. Reducing invasive potential of Buddleja will enable its continued use in the managed landscape. The hybrid ‘Asian Moon’ should be evaluated in areas where invasiveness of Buddleja davidii is a concern.
