Community Scientists Make A Difference

ADAPT and RENEW Scientists Make A Difference at Seed Savers Exchange

The 2018 community science programs, consisting of 80 Seed Savers Exchange members, helped us take another giant step forward in preserving our collection. A total of 62 members participated in the ADAPT program, while 29 took part in the RENEW program—and some members did both. We are tremendously grateful for the passion and dedication that drives our member volunteers to help us pursue our mission.

Update: Community science programs, including ADAPT and RENEW, are now open to both members and non-members to participate.

The 29 members who took part in the RENEW program helped us with the crucial task of regenerating our collection. These 29 members grew 41 varieties for fresh seed that will both ensure the survival of these varieties in our seed bank for decades to come and make them available to the public through our seed Exchange. These efforts go to the heart of our mission at Seed Savers Exchange.

Participants in the ADAPT program gave us invaluable feedback on 14 varieties from our collection that were selected for ADAPT because of their interesting and unique qualities. These varieties were grown by participants from 31 different states across USDA hardiness zones 4-9.

ADAPT participants sent us feedback on the varieties through an online survey for traits such as vigor, productivity, and flavor. Participants also gave each variety an overall score and noted whether or not they would grow the variety again.

Insights into some of the varieties grown by ADAPT participants follow. All of the varieties are available from Seed Savers Exchange through the Exchange.

Cabbage 179 – ‘Filderkraut’

A favorite of many, ‘Filderkraut’ is undeniably a charismatic cabbage. It is late to mature and requires up to three times the amount of space of other cabbages—but patience pays off.

Its huge, stunning heads are best described by Patricia Eller of Washington State: “I loved this cabbage! The cone shape was really a conversation piece. It was awesome to watch it get bigger and bigger!”

Bjorn Bergman of Wisconsin had good advice for growers: “This is a very long-season cabbage that is similar in maturing time to Brussels sprouts. Next season I would plant them the same time that I plant Brussels sprouts so they mature later in the fall for late-season kraut-making.”

In fact, this cabbage takes so long to mature that one participant thought it was a leaf cabbage and gave up on it before it started forming a head.

Most agreed that ‘Filderkraut’ was exceptional for ferments, with one saying that it provided lots of liquid for covering. Seven of eight growers said they would grow this variety again.

Pepper 444 – ‘Italian Sweet Fryer’

This huge, sweet, frying pepper was popular for its flavor and productivity. According to Kathleen Davidson of Illinois, “sautéing (and grilling) really brought out the sweetness in this variety.”

Others enjoyed the flavor raw, describing it as sweet and mild. All growers agreed that the plants are tall and need to be staked, reaching 5′ tall in Sondra Feldstein’s garden in central Iowa.

A few growers, including Linda Holmes of Wisconsin, noted that this pepper outperformed others under disease pressure: “The peppers that are our old standbys did very poorly. The ‘Fry’ was the only plant that gave us more than three peppers.”

Tomato 948 – ‘German Extreme Dwarf Bush’

There is a tomato for every occasion, and even though the majority of growers did not think highly of ‘German Extreme Dwarf Bush,’ it still had its cheerleaders.

Debi Bonkoski summed it up for most by saying, “This variety seemed to struggle in the garden.” The culprits ranged widely from thrips (Howard Nemerov of Texas), to wilt (Tim Noyes of Florida), to septoria (Kathleen Davidson of Illinois).

Despite this, the tomato did have some redeeming qualities. Its short stature and early maturity make it a good choice for container gardening.

As for all-important flavor, Tim Noyes was calculated in his description: “Definitely not going to win any awards, but a good early tomato.” Most others were similarly half-hearted in their praise of its flavor.

Okra 12 – ‘Poole’s’

Rarely is there consensus like there was around the quality of ‘Poole’s’ okra. All four growers would recommend the variety to others and regrow it themselves.

Jake Weakley of Missouri said that it became his favorite variety: “I really enjoyed the flavor much more than ‘Clemson’ okra.” Others praised it for its tremendous production and long pods that “stayed tender even when they were 4 -5″ long,” according to Patricia Eller of Washington State. We at Seed Savers Exchange happen to agree.

Melon 591 – ‘Gropp Pie Melon’

Feedback for this melon reiterates the fact that successfully growing old family heirloom melons can be a real challenge.

The plants in Sondra Feldstein’s Iowa garden succumbed to disease during a wet August after “starting out beautifully.” At Seed Savers Exchange, we can empathize with melon heartbreak.

Jonna Flickr of Missouri encountered another common problem. “I wasn’t sure exactly when to harvest. These are to be picked slightly under ripe for pies, but I didn’t know how to tell when that was.” She goes on to say, “They tasted pretty good when fully ripe and eaten fresh.”

Laura Kutka of Wisconsin disagreed. “We found that we did not care for the taste; it was bitter and sweet while still having a ‘vegetable’ quality to it.” When asked whether she would grow this variety again, Sondra kindly replied: “I always give things a second chance.”

Lettuce 20 – ‘Self-Seeding’

Perhaps unsurprisingly, most of the 13 participants who grew ‘Self-Seeding’ lettuce found that it was quick to emerge and quick to bolt. All grew this as a spring crop, but more than a few people, including Sondra Raines Brooks of North Carolina, remarked that they would like to try it as a fall crop, suspecting it may not bolt as quickly then.

Even before it bolted, the leaves were a bit rough and the flavor too bitter for Michael Cole of Wisconsin.

Several growers expressed interest in its flowering genetics, and Kathleen Davidson was impressed with how quickly the seed heads went from closed to “open like a dandelion” compared to other varieties.

One could conclude that if you want a low-maintenance lettuce and grow many successions throughout the season, ‘Self-Seeding’ might be the one for you. Or your chickens.

Tomato 6565 – ‘Large Yellow Tomato’

As spoiled for choice as we are when it comes to tomatoes, glowing reviews such as those for the aptly named ‘Large Yellow Tomato’ must indicate something special.

Lindsay Pepper of Iowa didn’t withhold any praise when she said, “Great! Loved it fresh. Loved it cooked. Beautiful plant, beautiful fruit. Productive.”

John Karon of New Mexico was equally impressed: “They were very vigorous and had wonderful production. Great flavor, as good or better than ‘Dr. Wyche’s Yellow’—my standard for yellow tomatoes. This variety is a real winner!”

Big flavor sometimes means big plants, which holds true for this variety. Lindsay will have to adjust her trellising system when she grows it again next year: “Grown in a raised bed—needed more support than I gave. Broke the tomato cage. Sprawling.”

We’re already looking forward to working with future community scientists—and we hope that includes you!

ADAPT

The Community Science ADAPT program is a fun and exciting way to get involved in Seed Savers Exchange’s mission of preserving and sharing our food crop heritage. Participants in this program trial varieties from the seed bank in their own gardens and send us feedback on their performance. This information helps us better understand the adaptability of these varieties to different environments and guides our selection process for new introductions into the Seed Savers Exchange catalog. ADAPT is suitable for gardeners of all levels

Sign-ups for the 2025 ADAPT program have closed. If you’d like to join us next year, please fill out the form, and we will be in touch in early January 2026 with more information on what trials we’re offering and how to participate.

Renew

Are you an experienced seed saver? Then sign up for the RENEW program and help us regenerate rare varieties from the collection.

Seed Savers Exchange’s location in northeast Iowa presents challenges to regenerating certain varieties. Some varieties may require a longer growing season than this climate affords, while others do not overwinter well (or at all) here. The time and care required to participate in this program are significant, but they go to the heart of our mission.

If this program interests you and you feel that you are an experienced seed saver, please email Briana Burke, seed bank manager, at [email protected] or call (563) 387-5685.

If this is your first year, anticipate a 20-30 minute phone call to talk about the program and see if this is a good fit for your system.
