Earliest spring is red

silver maple flower

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, […]

Carbon tax on beech trees!

Beech drops

A serendipitous encounter with a magnificent population of beech-drops on Peters Hill has really made my week.

It obtains all of its organic carbon by invading the fine roots of American beech trees (Fagus grandifolia). Not a touch of green can […]
