It's not from Cambo.
Not one of Ian the Christie's finds either.
Turns out it was one Ian Y found and Ian Christie the Second kind gave him from the Castle.
The plot thickens because on closer inspection in better weather there are different marking = on the flowers... from bulb to bulb in the little group and even from one inner to another on one flower!
More research needed over some years, the BD reckons, to see what is going on with this little cutie.
