W. Atlee Burpee and his family used the cottage on the farm as a weekend residence. The farm also served as the company's test garden for plants. Many plant varieties and hybrids were developed on the farm. You can read more about the site here.
The building to the left in the above picture is the seed house, the building on the right is the farmhouse.
There are several gardens on the property for both perennials and vegetables.
While walking through the kitchen garden I tried to take note of the various trellises that they were using for plants.
They used these red cages for almost all of their tomatoes:
The only exception I saw were these teepee type cages:
I like how they built teepee's for the sweet peas and then covered them with netting to better allow the vines to climb up the structure.
The next open house is in August and they will have tomato samples to taste test!
