Eminent panicle hydrangeas

There are certain times of the year when the Arnold Arboretum must be inhaled to round out the full experience. 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, […]

Early spring flowering is well underway at the Arnold Arboretum. Of special note today, are those wind-pollinated species whose flowers are essentially reduced to little more than the structures that produce pollen or seeds (no need for showy petals to attract pollinators). Among temperate woody plants, these early spring wind-pollinated taxa typically have unisexual flowers, […]

Samaras in the sun

Acer samaras

This past week has been an unbroken streak of sunshine and intense blue skies in Boston, with crisp cold temperatures—perfect for extended walks in the Arnold Arboretum.

Heptacodium miconioides

Seventy-three years is a long wait. That’s what it took between the Arnold Arboretum’s Ernest Henry Wilson (the great explorer of Asian plant biodiversity in the early twentieth century) first observing seven son flower (Heptacodium miconioides) in Hubei in 1907 and its arrival in the living collections here in Boston. Only in 1980, with the […]
