Hi,
I am gradually getting through my NARGS seeds and am stuck on Oxytropis multiceps. I have not been able to find anything on the net and it is not in any of the Deno seed germination lists, nor on Ontario Rock Garden Society germination database nor the Tom Clothier site.
Any advice gratefully accepted... although I have only a few seeds so can't choose too many options. :O(

Does it have any other names ? ----maybe there is information under another name.
I have never heard of it. Good luck with the NARGS seeds.
I did a winter sow of the first round,but now am working through the ones
which came from the Surplus round.

It has the obscure common name of Nuttall's Oxytrope... the USDA plant profile is here: http://plants.usda.gov/java/profile?symbol=OXMU

Haven't yet found out what time of year it flowers.

It was one of the alternative choices from the Surplus round...

No big deal but it would be nice not to give it a fatal treatment!

As for any Oxytropis (and indeed for any pea family seed), simply scarify the seed and you'll get germination rapidly. Scarification routinely gives germination in days (even after one day) for me, versus weeks and months for people who don't scarify the same species.
You can scarify by rubbing the seeds against a flat file to abrade through the hard seedcoats; it becomes guess work with smaller seeds as to judge how effectively you've scarified them - be careful not to grind them into dust.
By the way, there is a great deal of germination info on the NARGS site... you don't have to find that particualar species to find useful information (as I said, all pea family seeds should be treated the same way for best/fastest germination), and simply asking there will also yield lots of advice from experienced people.

Great; Thanks. Will do. THe seeds are v small, so carefully does it I guess.
Incidentally, I tried to get on the NARGS site today and it wasn't there, just a hosting company page. Does anyone know what is happening there???

There is a temporary problem with the NARGS Forum site... it's being worked on. Apologies 'til it's fixed again.

The problem has been solved and the NARGS site is functioning as usual.

I have spent an anguished couple of weeks thinking how I can scarify these seeds. They are only about ľmm in diameter. Holding them in tweezers won't give the required stability to file them... and can't really hold them steady enough to keep them in focus with my magnifying headset that I use for such tasks.

I am thinking maybe hydrochloric acid might work - since it would be experienced by seeds eaten by birds, mice, etc for "sowing" elsewhere.

Question is, how long. The HCl that I have is 23% dilution with water and I don't want to do any fancy chemistry to make it stronger (I'm clumsy and accident prone!).

I thought maybe put all of the (6) seeds in then take one out after 30 minutes, another after an hour, another after 90 mins and another after two hours and the other two after " & 4 hours respectively. Wash the seeds in water after removal to get rid of remaining surface HCl.

Does that sound good? or stupÓd???

Just set a few of the seeds on a flat file and rub them across the file with your finger... Believe me, it works. I do this with all pea family seeds and many others including many where the seeds are too small to grasp individually.
There's no need to resort to HCL (and 23% is plenty strong enough that one should be careful with it).

It is also known as "loco weed".

To scarify small seeds, I place them between sand paper,
and place the sand paper in a plastic bag. Then rub them through the sand paper and bag.
The bag is just there to catch the seeds if they try to escape.

A common name for the many hundreds of species of both Oxytropis and Astragalus...
