Electric typewriter designers were probably keen gardeners

The similarity between the passion flower and the typewriter daisy wheel is obvious, but did they get the idea from the flower or was it coincidence?

How far can coincidence stretch? Look at the this flower as compared to the typewriter golf ball.  I think it's some relation to the thistle but not sure.

I had a whole thing going here with corn-on-the-cob paint rollers, lupin flower loo brushes and fig light bulbs, but I think I’ll leave it.
