Connecticut’s Barberry phase-out
The Connecticut Nursery and Landscape Association (CNLA) recently called for a voluntary ban of 25 cultivars of Japanese barberry (Berberis thunbergii). The parent species – in photo to the right - has overtaken much of Connecticut forestland and large stands of the thorny green woody shrub appear to act as optimal host areas for Lyme-disease carrying ticks. As reported by CNLA, the 3-year phase-out includes the 25 cultivars that are most prolific at seed production. Another 18 cultivars – those at the bottom 10% for seed production – are not included in this voluntary ban.
