I got some seed from the 2010-2011 NARGS seedex for Trifolium trichocephalum and grew it. It is strange that I can't find any particular reference to it other than from species lists. The Plant List indicates that it is a valid species name and evidently the type location for it was "Taur.- Caucas." (Taurus Mountains-Caucasus region, I assume).
Can anyone, perhaps the seed donor, tell me anything more about it? The height in the seedlist was shown as 30-70cm, so I'm hoping it will provide interest in the border along the same lines as Trifolium rubens does. I guess I will get to see it in growth this year, but it's very curious how little one can find on it in a search!
