I like to trade.  The only problem is that most of what I am looking for is pretty hard to obtain.  If you have something on the list, please contact me at bill@cultivariable.com to work out the details.

Here is what I am looking for:

Achira (Canna edulis): Varieties that are not the standard ornamental cannas.  Seed saved from any achira variety.

Ahipa (Pachyrhizus ahipa): Varieties other than the single common variety in circulation in North America.  Ahipa/Jicama hybrids.

Apple (Malus domestica): Seeds from uncommon varieties.  Preferably where pollination by crabapple is not a certainty.  This is an easy one.  If you are eating an uncommon apple variety, just dry the seeds on a paper towel and you have instant trade goods.

Arracacha (Arracacia xanthorrhiza): Seeds from any source.  Varieties other than the Puerto Rican clone that is commonly available in the USA and the Australian/Zaytuna clone.

Australian Parsnip (Trachymene incisa): Seeds from any source, but particularly any collected from the southern part of its range – around Canberra or even farther south.

Bitter Melon (Momordica charantia): Seeds from the most northern part of its range or from varieties that fruit well in cool temperate climates.

Chinese artichoke (Stachys affinis): True seeds.

Cloudberry (Rubus chamaemorus): Seeds from the southern part of its range, especially from NW Washington, SW British Columbia, and Vancouver Island.

Commelina coelestis and C. tuberosa: Seeds, tubers, preferably from wild types or varieties that are not commonly available in the nursery trade, as I already have those.

Dahlia (Dahlia spp.): Any dahlia that has good flavor, with the exception of Yellow Gem, Black Jack, and Kaiser Wilhelm, which we already grow.  The following species dahlias: D. tenuicaulis, D. campanulata, D. apiculata, D. atropurpurea, D. brevis, D. cordifolia, D. pteropoda, D. rudis, D. spectabilis.  I am possibly interested in other species dahlias as well.

Erythronium species: Seeds or bulbs of edible species.

Florida betony (Stachys floridana): If you live in the Southeast, you may well be trying to eradicate this species from your yard.  Might as well send them to me!

Gooseberry (Ribes uva-crispa): Seeds from varieties other than Hinnomaki Red, Hinnomaki Yellow, Invicta, Captivator, Jahn’s Prairie, Leepared, Pixwell, and Poorman.  I prefer seeds, but will consider cuttings at the right time of year.

Groundnut (Apios americana): Varieties or seeds.  I have ‘Densituberous’ and a large, unidentified LSU variety.  I would love to try anything else, wild or domesticated.  If you live in the right place, this should be an easy one – find some wild groundnuts and harvest a few.  Also, tubers or seeds from Apios priceana and Apios fortunei.

Ipomoea pandurata: Seeds from the northern part of its range (NY, NJ, PA, CT).

Jerusalem artichoke (Helianthus tuberosus): Unusual named varieties, wild collected varieties, true seeds.

Kiwiberry (Actinidia arguta): Seeds from unusual varieties.

Marsh woundwort (Stachys palustris): Wild collected seeds or clones with superior performance.  Particularly interested in wild-collected tubers from NE US.

Mashua (Tropaeolum tuberosum): Varieties that we don’t currently list in the wiki or true seeds obtained from South America.

Mauka (Mirabilis expansa): Any variety other than Blanco or Roja.

Oca (Oxalis tuberosa): Varieties that we don’t currently list in the wiki or true seeds obtained from Andean sources.  Varieties that you have grown from seed that are superior in your climate.  Seeds or tubers of any other Oxalis species in the Oxalis tuberosa Alliance.

Onions (Allium cepa): Unusual perennial onions, especially rare potato onion varieties.  Any top-set onions other than the Egyptian walking onion and Fleener’s.

Oxalis tetraphylla: True seeds (not bulbs).

Pediomelum spp. (Psoralea spp.): Any species other than the common Prairie turnip (P. esculentum).  I am particularly interested in getting some Pediomelum californicum / Psoralea californica.

Perennial broccoli, cabbage, cauliflower, kale, etc. (Brassica sp.): We have purple tree collard, green tree collard, Haa collard, Cosmic kale, interested in others.  Would love to get a cutting of Daubenton.

Potato (Solanum spp.): True seeds from unusual varieties.  Clones of Andean origin – 2 tubers is usually all I want as they go immediately into culture.  I’m generally not interested in white fleshed American and European varieties, even if they are rare.  Any wild species in the Petota section.

Red Huckleberry (Vaccinium parvifolium): Seeds collected outside Western Washington, particularly at the fringes of its range.

Rhubarb (Rheum rhubarbarum): True seeds from unusual varieties.

Rice Root (Fritillaria camschatcensis): Seeds or bulbs, other than those commonly available in the nursery trade.

Salmonberry (Rubus spectabilis): Seeds collected outside Western Washington, particularly from isolated populations.

Saraviqui (Prionosciadium townsendii): It sounds interesting, but I can’t find any sources.

Sea kale (Crambe maritima): Root cuttings of named varieties other than Lily White or wild collected seeds.  Seeds of other unusual Crambe species.

Skirret (Sium sisarum): Any named varieties or clones with superior performance, seeds collected from wild or feral populations.

Smallanthus (Polymnia) species: Anything other than S. uvedalius.

Sweet Potato (Ipomoea batatas): True seed or varieties known to perform well in cool climates (better performing than Georgia Jet, which does not crop in our cool summers).  If you only have small quantities of seed, don’t waste them on me, as survival in this climate is very poor, but if you are lucky enough to get a bumper crop, I’d sure like to try some.

Tigridia pavona: Seeds, preferably from mixed populations.  Possibly other edible Tigridia species.

Triteleia grandiflora: Seeds or bulbs.

Tropaeolum species: T. smithii, T. argentinum, T. patagonicum, T. hookerianum, T. austropurpureum, T. sessilifolium, and probably others.

Turnip Rooted Chervil (Chaerophyllum bulbosum): Any named varieties.  I know they exist, but I can’t find them.  Seed from wild or feral populations.

Ulluco (Ullucus tuberosus): Varieties that we don’t currently list in the wiki or true seeds obtained from Andean sources.

Yacon (Smallanthus sonchifolius): Varieties that we don’t currently list in the wiki or true seeds obtained from anywhere.

Yam (Dioscorea species): I’ve never grown any, but people keep telling me that I should.  So, any yam species that can perform well in a cool summer climate.

Yampah (Perideridia gairderni) and western yampah (P. erythrorhiza): Seeds, plants, roots, whatever you have, from anywhere.
