Corylus avellana

The Arboretum has a large collection of filberts (Corylus sp.). The oldest, Corylus americana, Acc. # 1229*A, was collected in 1873, a year after the Arboretum’s founding, from Liberty, Virginia. Since then, the collection has grown to include species from Europe, Japan, China, and the Republic of Korea, totaling 51 plants. Most accessions have been wild-collected, with the data revealing a who’s who of Arboretum plant explorers and their colleagues at partnering institutions. Some form dense, ever-broadening rhizomatous shrubs while others are large pyramidal trees. The nuts are edible, if you can collect them before they are spirited away by local wildlife. Arboretum Gardener Robert Dowell has a fondness for filberts and wonders why they aren’t more commonly grown in Massachusetts. Robert will present an overview of the collection and visit several species located in the Bradley Rosaceous Collection. Meet at 4:00pm on Tuesday, September 8 at Acc. # 1299*A.

If you don’t own a saw but intend to purchase one, wait until you’ve attended the class to learn which styles and features are best for your size and needs. Participants should wear work boots and bring safety goggles, gloves, and ear protection. Dress for the outdoors and bring a lunch and beverage.
