“It is a real treat when I’m doing yard work—or any time I walk to or from the front door—I can see a plant that came from the Arnold Arboretum. A very meaningful connection!”

Sarah Freeman, Arboretum member

Each spring, we promote the cultivation of exceptional woody plants in our region through the Arbor Day Seedling Program. This exciting benefit of membership is offered to current members at the Arbor Day ($150) level and above.

The Arbor Day Seedling program helps us connect with our community through remarkable plants, and is offered with thanks to members for their generosity to the Arboretum. We hope you will enjoy celebrating Arbor Day or Earth Day by planting a seedling associated with our collections in your garden.

In 2024, we are pleased to offer the ‘Arnold Promise’ witch-hazel (Hamamelis × intermedia ‘Arnold Promise’) as our Arbor Day Seedling. This cold-hardy shrub or small tree results from the chance hybridization of the Chinese witch-hazel (Hamamelis mollis) and Japanese witch-hazel (Hamamelis japonica) in the Arnold Arboretum landscape. Its late winter flowering—a staple of its parent species—conjures the approach of spring. Flowers are piquantly fragrant and bright yellow, emerging on branches that lack leaf retention for a more visible and vibrant display—particularly in snowy landscapes.

Qualifying members may pick up their Arbor Day Seedling at our Weld Hill Research Building (1300 Centre Street, Boston, MA 02131; see map below) on: 

  • Wednesday, April 17 from 5:30–7:30pm 
  • Friday, April 26 from 8:00–10:00am 

This year, members will not need to register to pick up their plants in-person. Drive or walk up, give us your name, and we’ll give you a plant and answer your planting and care questions.
