Right now, different parts of the Arboretum are dominated by aromatic compounds volatilizing from the flowers of linden trees (Tilia spp.) and the magnificent panicle hydrangea (Hydrangea paniculata). With temperatures high and the sun intense, […]

Kalmia latifolia flowers

The small, fast Telico River is a jewel of east Tennessee’s Cherokee National Forest. Its clear waters tumble past moss-covered riverbanks while mountain laurels (Kalmia latifolia) abound on the steep, rocky hillsides.

A Thorny Obsession

Please don’t ask me to identify a hawthorn—or rather to distinguish one from another. As a bookwormish horticulture student, memorizing leaf shapes and bud characteristics for plant identification exams, I learned only the basics. In a house yard in the Midwest, I would feel confident saying that a hawthorn with layered horizontal branches and tear-shaped […]
