Garden Phlox (Phlox paniculata), left, a native perennial valued by humans and pollinators alike, offers vibrant, showy color and a potentially long bloom season. At right is a seedling of the invasive shrub Japanese Barberry (Berberis thunbergii) found growing in the woods in late April by a WGC member. Several invasive plant species are known to break bud and start greening up a bit before most of our native plants do.
