EPHEMERAL SEEDLIST 2000
Managed by Nancy Swell
Thanks to some very generous donors the seed list is open to all this year. For a while there, it was open to debate. Why is the seed listed here? This seed is regarded as having short viability. Some have been tested in controlled experiments (e.g., Salix with a half life measured in days), and some belong to genera or families where short seed life is common (e.g, the Ranunculaceae). In other cases, the seed does not die in dry storage, but strong inhibitors develop, and many years are required for germination. Trillium often germinates the same year if kept moist, but requires some time if allowed to dry out. In any case, all of this seed germinates best when sown immediately upon receipt. How does it germinate? A few of these species, like Salix, germinate promptly. Some germinate in the fall of the year, but may only form a radicle in that season. Most show their first leaves in the following spring. Some seed has additional germination requirements. Several seem to require gibberelins produced by fungi; you can provide it with some leaf mold. The commercially available gibberelin, GA-3, is not a cure all Sanguinaria requires gibberelins, but GA-3 is not an effective one. Other seeds may require light or dark. The majority of these species are woodland natives, and many of them evolved seed coats or seed appendages favored by ants, who carry them underground. If you have no better evidence, mimic its underground habitat dark, moist, and fungous; in other words, sow as you would anything, but include some leaf mold in the compost. The species is followed by the month of collection and the donors' initials.

Obtaining Seeds: Please read carefully
Obligations of the Requestor: To request seeds, send a self-addressed, stamped envelope to the donor; write the species name on the envelope. If you are requesting more than one species from a donor, send the appropriate number of envelopes. (Multiple forms of the same species can be counted on to mature at the same time, and are safe for a single envelope.) If the donor is in another country, obtain an International Reply Coupon or use acceptable paper currency. ( A dollar is usually accepted in Canada). You are responsible for appropriate packing and sufficient postage. Donors are not expected to reply or to send seed if you have not included enough postage and protective packaging. There is normally a charge in the US (7 cents) for hand canceling. Do not forget to enclose that. Donors are happy to hear the seed arrived safely, or, if it did not, let them know that the post office crushed them. Finally, do not ask for seeds after the date of collection given above. In cases where there was more than one date, the earlier one has been used.
Obligations of the DonorDispatch the seed on the day of collection. Ask the post office to hand cancel. If seeds are notoriously short-lived, you might supply a bit of moisture inside plastic wrap. For international requests, label the envelope: Garden seeds, no commercial value. In case of crop failure, it is your choice whether to write the request or, or to save the request for next year.
About the Ephemeral Seed Exchange/Call For Ephemeral Seeds
A number of us participate in an exchange of seed with short viability. When seed of this type goes through the seed exchange and dry storage it germinates poorly. Appropriate candidates are members of the Ranunculaceae: Aconitum, Adonis, Anemone, Eranthis, Glaucidium, Helleborus, Hepatica, Ranunculus, Thalictrum; and the genera Asarum, Colchicum, Corydalis, Cyclamen, Dicentra, Dryas, Erythronium, Galanthus, Hacquetia, Hylomecon, Jeffersonia, Lysichiton, Salix, Sanguinaria, Shortia, Stylophorum and Trillium.
This list is not exhaustive, but
please restrict offerings to species with known short viability or those which
exhibit dramatic differences in germination when sown promptly. If you have
seeds to offer, please fill out the form below and mail it in now - the
deadline is March 15. The list will be published on this page, in spring
newsletters, letters, or e-mails along with the procedure for obtaining seeds.
Some guidelines for submission:
* A modest offering is advised. If you submitted one or two last year, increase
it a little. Try to offer up to half a dozen species, but no more.
* There tend to be many offerings of some taxa. If you have a copy of last
year's list, choose items that were not offered or were offered by only one or
two donors. If you don't have last year's list, keep the one that comes out
this year for reference. I have last years list available for sending.
* Diversity is one of our goals. Last year we were short in Colchicum, and
Epimedium and there is never enough Shortia.
* Don't offer items from your garden that you haven't seen flower and fruit.
Wait another year.
* Don't be afraid of crop failure. If there's no seed, drop a postcard to the
requester and save the request for next year.
When the list is published, these
are the directions that will be given to requesters: To request seeds, send a
self-addressed, stamped envelope to the donor. (If the donor is across an
international boundary, obtain International Reply Coupons). Write the species
name on the return envelope. If you are requesting more than one species from a
donor, send the appropriate number of envelopes, though multiple forms of the
same species are safe for a single envelope. You are responsible for
appropriate packaging and sufficient postage. Donors are not expected to reply
or to send seed if you have not included enough postage and protective
packaging. Don't forget the postal surcharge of $.07 for packages that must be
hand canceled.
