Actually there are quite a few types (pheno's, etc.) that fall under the goatsweed umbrella. Maybe a dozen or more, so I've been told. Not much difference between the lot other than pod shape and more or less hairy. I believe it was member Smokemaster that coined the nickname (term?) "silver fuzzy's" for them and claims to have a dozen or so expressions in seed form. I've only grown two different expressions, a shorter stubby one similar to yours and the longer black cobra pheno.
