I think I've identified this right but I'd like some info please.... Is this Medicago Sativa. It's growing in the street next to our Box hedge. I think it's a really nice plant and colour. My questions are.... Am I right ? Is there a cultivated variety or Hybrid I can grow in the garden or could I save the seeds off this to grow myself ? Does it grow weedy and invasive if I do grow it ? Thanks all.
I found this bit of info about it @KFF plus a link on the plant till other members more knowledgeable on the plant answer also for you Alfalfa /ælˈfælfə/, Medicago sativa also called lucerne, is a perennial flowering plant in the pea family Fabaceae cultivated as an important forage crop in many countries around the world. It is used for grazing, hay, and silage, as well as a green manure and cover crop. Alfalfa (Medicago sativa) Medicinal plant benefits and pictures
