Banksia Pods are found in the state of Western Australia, roughly along a line extending from Perth to Denmark, and are generally harvested after April. I am currently out of stock of all grades of pods and do have a Waiting List (see below) for Whopper Pods. It will likely be February 2018 before I receive any more pods.
PLEASE NOTE . . . Though I occasionally get Whopper Pods up to 14-15" in length, they are EXTREMELY RARE. And the larger ones may not be better than the smaller ones in terms of seed hole uniformity, density or diameter/shape. Any pod over 9-1/2" long or 4" diameter is Whopper grade. Average size is generally 10-12".
