Mammoth Russian Sunflowers December 12, 2007
Reviewer: Edward Landry from North Attleboro, MA United States  
I loved my vegtable garden, but it was the Mammoth Russian Sunflowers (#55099P) that everyone looked at.  They were about 10' tall and one head was 14" across.  If anyone is looking for bragging rights, they should grow this plant.
