Raja, Since these are recent imports, some of which already had sheaths, and came bare root, I believe they were "force blooms" and therefore not a true representation of what they will look like once fully established.
Of the first two that bloomed, one plant had just one flower and stunted in size. The second plant had five flowers, but no "eyes" were present.
The pics below show the size of the second bloom, along with the bench full of gigas...
I don't have pics of the next two that bloomed, but maybe later today. This again had one stunted, and another full size, but this time the eyes were present, albeit the flower was lighter than the first. It may be just a standard that got mixed in with my order of Sanderianas.
