I like the smoothness of Red Fuseau but the tubers are so far from the stalk I have to dig everywhere. They are ok sized but it is so much work. The soil is great except a bit heavy right now with dampness. I miss the larger although knobbier tubers of Stampede.
From the sandy potato fields of Sherburne county, Windy River Eco Farm grows heirloom vegetables, flowers and herbs for Market and CSA. Been growing since 2008.
I saw an article about Genome Skimming in which researchers sampled genetic material from sunchokes and determined that the sunchoke is a recursively hybridized result of two different sunflowers: the Hairy/Ashy Sunflower and the Sawtooth Sunflower.
Fine; I'm just not sure the wild ancestor is much more useful than the wild ancestors of most of our cultivated plants, not that I want to discourage anyone's investigations; if you've got the enthusiasm, go for it, by all means; we have no idea what might result from your efforts. Best of luck! Stay in touch.

Eric Toensmeier has suggested that people try to cross sunroots with seed sunflowers in order to get a perennial seed-producing sunflower. As I believe sunroot seeds are edible as-is, I think they must not be as prolific as common sunflowers. But it's also possible that it's an issue of seed size.
I recently read an article in a formal ag journal describing perennial sunflower breeding at the Land Institute. To summerize it, the pollinated several clones of J. artichokes with pollen from oilseed sunflower inbreds. Seed set was low but non-zero. Many (most?) of the F1 plants didn't survive the winter, but some did. Seed set and pollen production on the F1s were low but again non-zero. Better than the seed set on the J. artichokes with sunflower pollen. Head on the F1 plants were bigger than any pure J. artichoke head, but smaller than the oilseed parent. Branching was reduced from the J. chokes, but all were branchedd and no plants had single heads. The F2 plants had better seed set, no suprise. They also had fewer branches, bigger heads, bigger seeds, fewer heads, but still no single heads. This was all the F2 plants, before human selection.
I'm all for increasing the genetic diversity of domestic sunchokes. But I think there is no need to recreate the species when there is so much unused natural diversity in sunchokes, especially the wild ones. But like Steev says, if it interests you, go for it. What I like most about this group is that so many people are doing things many gardeners would think are crazy. But people are getting good results. Not always maybe, but often enough I want to be part of it.
I was able to get several dozen of what look to be viable seed from a three year old patch of Waldspinel and White Fuseau sunroots cross pollinating each other. I'm excited to keep this process going with several more individuals/strains for continual building of genetic diversity for open-pollinated sunroots. I want to plant these in a wild context and for a population to be able to take care of itself and rewild back into the native seed bank.

Hi philagardener, my home base is in southeastern Pennsylvania in Chester county, not far from Philadelphia or Lancaster. Right around the DE/MD/PA tristate. I roam around the area quite a bit though and am invested also in the area of the lower Susquehanna river between York and Lancaster counties and the high Allegheny mountains of eastern West Virginia, especially around the Canaan valley. Basically, I'm Mid-Atlantic!

IIRC, Oikos Tree Crops was not only selling tubers from specific varieties of sunroot, but was also selling potted seedlings from random crosses. They're somewhat expensive (they sell only potted plants, not seeds, and sunroots don't set a lot of seeds generally) but you might want to take a look.
Fedco (as Moose Tubers) also sells several varieties, which shift with the year. That's where I got mine. Clearwater, Sporospelka, and Waldspinel.
I just sold Oikos 20 lbs. of the "Stampede" variety of sunchokes that I grow in my backyard. They often set more than one tuber per plant, some quite large, others medium to small size. I would love to try planting other varieties. Any suggestions appreciated.
I am in SE Tennessee, USA and they grow quite well here. I've also found a wild sunchoke that produces smaller tubers but quite tasty.
Excellent! Grow and make available: that's the deal! To paraphrase Ben Franklin ("We shall all hang together, or we shall all hang separately."), we shall all grow together, or we shall all fail to grow, separately.
Last year my mom bought both seeds and seed grown tubers from Oikos. The resulting plants from the tubers didn't set seed successfully their first year. I have the seeds stratifying now in the unheated greenhouse. Joseph sent me a tuber or so from his strains. I have to let the snow melt a bit before I can get out to my garden and plant them. It will be interesting to see if I get any seed back this year from any of them!
I planted a bag of tubers a few years ago from a CSA share my mom got. All one variety. They did great for awhile but dissapeared while I was away for a few years. I don't know if they didn't get watered or if it was just rodents eating them.
I have a couple clones in the yard of my parent's house of a single plant of sawtooth sunflower Helianthus grosseratus I propagated from seed back around 1999 or 2000. Because I only managed to propagate one plant it's never set any seed. I should shovel clone it and plant one near the Jerusalem artichokes. Any seeds produced would be probable hybrids. Though I have planted a couple other native perennial sunflower species out on my land- one last year and another that has been struggling but surviving. Will see if they come back this year, got both from the annual sale of my local chapter of the Montana Native Plant Society sale. Different species in different years but I don't recall which- maybe I will key them if they bloom. I've planted other additional species in the past that have died out including I think Helianthus nuttallii and Maximilian Sunflower.
I am also going to grow some annual sunflowers including Hidatsa #1 sunflower seed I saved from a plant next to Autumn Beauty (or similar name), some Arikara sunflower, and some wild annual sunflower I collected seed for. I also expect some volunteers from last year and from black oil sunflower seeds we feed to the birds.
I planted some of Joseph's in the fall of 2015 and got a good 1/4 cup or more seeds from them in 2016. There were actually more but I didn't mess with collecting them all. I picked flowers from some wild ones and attempted to cross them and expect at least some of the seeds are likely crossed but of course I don't know which ones. I was thinking of sprouting them in pots to see if they sell at the farm market.
Flowering did not coincide with any of my annual sunflowers so I wasn't able to do any crossing with them. I'll try that again this year.
