Over the decades I'm sure I have grown several dozen milkvetches in my various gardens. As gorgeous as many of the American species are, I have noticed that the Eurasian ones are more apt to stick around. This Turkish species came to me from Jim and Jenny Archibald over 20 years ago. I can't remember if it is Astragalus alyssoides or A. alyssifolia (it was one of the two)...It certainly doesn't look like any alyssum I grow! My original plants grew for almost a decade at my last home. I grew some from seed when I moved to Quince and they are still with me ten years later. I must remember to collect a few more seeds or try some cuttings: it's a sweet little plant!
