Double peonies have five or more outer petals with the central stamens and carpels transformed into petaloids that make up the main body of the large, full flower. The central petaloids are largely indistinguishable from the outer guard petals. Bomb peonies are often considered a sub category of the double form. They are characterized by a row of outer guard petals surrounding a pompon tuft of dense petals. The central petaloids have become very broad but can still be distinguished from the outer row of guard petals.
All types do well in Kansas flower gardens, though the double types are the most popular.
