Gomphrena is one of our favorite flowers here at the Farm.  This variety is called Ping Pong Purple.  The blooms are fluffy balls that are produced in mass on the plant.  This is one plant that comes in a 3.5" pot.
 
Grows 10"-12" tall and 16"-20" wide
Blooms all summer
Great for cut flowers and also can be dried for dried flower arrangements
Works very well in the landscape or flower bed for a mass planting or can be grown in containers also
