Ah yes, that is definitely a flower. Still, good eye! 
It is missing the "donut" and it's not blue, so it appears that these two features really set the VM and Scivias apart.
I spent some time looking now and all I got is this:
1) The Liber Floridus draws the planets like flowers. Maybe that's a little bit closer than floral decorations? (top left in image)
2) "The Planet Jupiter Represented as a Bishop on Horseback" with a familiar blue star in the sky. The MS is unfortunately a bit late (1464) but this is not the first time it surfaces in Voynich studies. Source: You are not allowed to view links. Register or Login to view.
