I'm not sure it's Glen Ellen.. It doesn't look as heavily striped as your picture... but it is on the shorter side..
I have this yellow, that I was thinking may be "Alta California', but the person I got it from doesn't think so.. The color in my pictures varies with the light and time of day they were taken.
"Happy Days' has a larger flower.. here's a picture I took of a falls from the one I think may be 'Alta California' and 'Happy Days' on the left.
I haven't seen 'Argosy' in person, but it looks like you may on the right track... I'll be interested to see what Arlyn or Lori thinks..
