One can't help but notice the spicebush grove on the North side of Bussey Hill Road near the Lilac collection at the Arnold Arboretum. The persistent tawny-tan foliage of Lindera umbellata and Lindera angustifolia are nearly indistinguishable from one another. Both shrubs have narrow glossy green foliage with silver undersides earlier in the season. The greenish-yellow flowers in April produce small round black fruit on female plants. L. angustifolia has strawberry pink foliage in autumn and is hardy to zone 5 while L. umbellata leaves turn yellow in fall is only hardy to zone 6.
