I have read that Japanese barberries are an invasive plant to be avoided. How does your Berberis thunbergii 'Crimson Pygmy' differ from these invasives?

Japanese Barberry (Berberis thunbergii) is reported as invasive in 20 states, including Washington, D.C. Crimson Pygmy is no different so I would avoid planting it, or plant it in a container so it can be controlled. Or, you might choose an alternative: Many attractive native shrubs are available that make great substitutes for Japanese barberry. A few examples include bayberry (Myrica pensylvanica), ink-berry (Ilex glabra), winterberry (Ilex verticillata), arrow-wood (Viburnum dentatum), mountain laurel (Kalmia latifolia), ninebark (Physocarpus opulifolius) and hearts-a-bustin' (Euonymus americana).
