Difficult Creek, Difficult Management Choices, W. John Hayden
Biology Faculty Publications
Virginia is blessed with many botanical wonderlands; see Chapter 4 of the Flora of Virginia (Weakley et al. 2012) for thumbnail sketches describing 50 of these special places. One such treasure, Difficult Creek Natural Area Preserve, is home to a thriving population of the 2019 VNPS Wildflower of the year, Ceanothus americanus (New Jersey Tea). Paradoxically, however, our featured wildflower of last year is inextricably linked to a difficult conservation management decision.

Biology Faculty Publications
Specialized pollination systems are the source of some of the most compelling stories in natural history. There is something appealing to the human psyche about what seems to be a reciprocal agreement between a given plant and its dedicated pollinator: the plant attracts a pollinator and provides ample nectar and/or pollen as a reward for the pollinator’s service in moving pollen from anthers to stigmas while foraging for food. Of course, these organisms have neither signed agreements nor memos of understanding. Instead, it has merely proven to the benefit of the plant, over time, to form certain floral structures, and …

Nitrogen Fixation In Roots Of Ceanothus, W. John Hayden

Roots are usually out of sight and, therefore, out of mind. But as any good gardener will tell you, it is of utmost importance to understand those unique plant organs, even if their essential functions occur hidden from cursory observation. The red roots of the 2019 VNPS Wildflower of the Year, Ceanothus americanus, are particularly important because they host symbiotic bacteria that perform the essential function of nitrogen fixation. These prominent, knobby, distinctively pigmented roots are also the inspiration for the common name Redroot, applied to many species in the genus.
