Dahlia

From PyroGuide

Silver dahlia

Essentially the same as a peony shell, with an standard bursting charge, but with fewer and larger stars. These stars travel a longer-than-usual distance from the shell break and usually droop considerably before burning out. For instance, if a 3" peony shell is made with a star size designed for a 6" shell, it is then considered a dahlia. Some dahlia shells are cylindrical rather than spherical to allow for more large stars.
