We invite you to join our public tomato trial and be a citizen scientist! Help us gather information by growing trial tomatoes in your garden and reporting the results. By having participants grow the same varieties in home gardens all over the county, we will learn how they perform under a broad range of growing conditions. This valuable data can help identify new varieties to offer at future Spring Garden Fairs and help gardeners make informed choices about what varieties to plant.

How it works

Participants will

• buy designated trial tomatoes at our Spring Garden Fair
• grow them in their gardens this summer
• report their results SeedLinked online or using the smartphone app

Examples of data we will be asking for:

• Date you plant the seedlings
• Date of first ripe tomato
• Flavor of tomato
• Health and vigor of plant
• Productivity (according to your opinion; we won't expect you to count or weigh your harvest)

Getting started with the trial

Growing Requirements

Make sure you have the appropriate conditions to successfully grow tomatoes this summer. Your growing space should:

• have reliable access to water
• receive at least 8 hours of sun per day
• have adequate growing space. Tomatoes need about 2 square feet per plant or a container at least 18" to 24" wide and deep per plant.

About growing tomatoes

2025 Trial Varieties

Our 2025 trial tomatoes were top vote getters in our internal tastings, as well as being healthy and productive. All three are open-pollinated (OP), meaning that saved seed will produce true. 

Green Doctors

These green cherry tomatoes have a fabulous, sweet, balanced flavor. They soften and turn slightly golden when ripe. They originated as a chance green variation of the white Dr. Carolyn cherry tomato, found growing in the garden of Dr. Amy Goldman. The name refers to the two doctors, Dr. Goldman and the late Dr. Carolyn Male, two renowned tomato enthusiasts.

Indeterminate. OP. 75 days.

Queen of the Night

These stunningly colored small tomatoes (3–3½ oz) start off with green and purple-black skins, then become streaked with red/orange/yellow as they ripen. The interior is bright red and the flavor is deliciously rich and sweet. A German heirloom from the Rhine region of Germany.

Semi-determinate (5–5½ ft). OP 80 days.

Sart Roloise

This gorgeous beefsteak tomato is golden yellow with purple shoulders and a pale gold interior. The flavor is fruity and complex, low-acid and mellow. It's a cross between White Wonder and Baby Blue tomatoes, bred by Roland Boulanger, Sart Eustache, Belgium. (Pronounced sar-roh-lwaz)

Indeterminate. OP 85–90 days.
