Lonicera morrowii — Morrow's honeysuckle

Facts

Look for hollow stems, leaves that are hairy on the underside, and finely-hairy, white flowers on the exotic shrub Morrow's honeysuckle. It was introduced from Japan by Dr. James Morrow in the 1860's. Used extensively as an ornamental plant with showy, white-pink flowers, it spreads easily in the forest understorey and is considered invasive in Massachusetts and Connecticut.
