2020 Seed Exchange Workshops - volunteers welcome
Workshops to clean and package seeds for our Seed Exchange begin on Tuesday, January 28, and continue into February. The workshops are held every Tuesday, Wednesday, and Thursday from 10:00 am – 2:30 pm at The Henry Foundation for Botanical Research, 801 Stony Lane, Gladwyne, PA. Workshops are a great way to meet and chat with fellow members while we work. They are also a wonderful way to learn new things about seeds and seed propagation. Most importantly, the workshops are fun! Bring a lunch for yourself and maybe a snack to share. Coffee, tea, and water will be provided. To schedule a workshop day, please contact our volunteer coordinator Polly Garnett at [email protected], 610- 695-9135.


Since the Seed Exchange workshops may coincide with the worst of the winter's weather, we will notify volunteers of cancellations with an announcement on the home page of the HPS/MAG website, www.hardyplant.org, by 8:00 am of each workshop day on which the weather is a factor. For those without access to a computer, if the weather is bad, please call Susan Doblmaier at 215-542-7865.

What is the HPS/MAG Seed Exchange?

Since the fall and winter of 1993-94, the Seed Exchange has been one of the activities that makes HPS/MAG stand out from all of the other plant societies in the Mid-Atlantic region. Each year, as the fruiting season for a plant comes to an end, dedicated Society members collect the seeds and forward them, along with a description of the plant, to the Seed Exchange Team.  This information is then used to create the Seed Exchange Catalog. Click here to view a copy of the 2018-2019 catalog. 

In early January, Society members are invited to order seeds for a small fee. Later in January and February, dozens of volunteers meet at The Henry Foundation for Botanical Research in Gladwyne, PA to sort and divide seed into packets to satisfy the orders. Thousands of work hours and volumes of gardening knowledge go into providing this valuable exchange of seeds. Any member can submit seeds or volunteer to clean and sort seeds. Want to join the fun? To volunteer for any Seed Exchange Workshop, contact Polly Garnett at  [email protected].
