Answer: "Wide Brim" is a specific named cultivar of hosta. The particular species or crossings of species used to develop the original Wide Brim plant from seed is not noted, thus, as is typical with so many hosta cultivars, the designation of x to designate it is the specific named variety.
Wide Brim is quite popular and is produced in large quantities for the marketplace. In most cases it would be propagated most efficiently in large batches by tissue culture, however perhaps in smaller quantities it could also be achieved by division. Thus the plants should be genetically the same, cloned you might say, and without chance of any seed strain type variation. I hope this answers your question.
