This may work and it may need tweaking either way it's my theory on how to scare critters from your garden or flowerbeds
You Will need
Scrap wood 1/4" thick
1/4" Dowel rod
2" x 2" x 3' board
An outdoor wood glue
1 flat washer with a 1/4" center hole
1 fender washer with a 1/8" center hole
a small 1/2" drywall screw

Step 1: Fine Points
The hole in the center should be slightly larger than the 1/4" dowel rod but not to big or instead of spinning the flower will wobble .
Space out your pedals evenly or your flower will be to heavy on one side and not spin in the wind .
Use a very good grade of wood glue made for outside exposure .
Spread your glue on your pedals thinly and evenly as to not weigh down one more than the other.
Center drill your 1/4" dowel rod before inserting the screw or it will split the dowel rod and spread the rod and keep the flower from spinning .
Sharpen your 3' 2x2 at the bottom so it's easier to put into the ground .
Push your plastic tab block 1/8" into the back of the flower blades so that the blade spins freely in a light breeze and more might hinder it's movement
( If my Theory is correct reflection and noise with movement will scare off any pests that might bother your garden for an extra aside hang a small bag from the center of the 2x2 with a small bare of soap in it to keep away deer and other critters who scatter at smell instead of movement )
