Bioterrorism in Alaska?

Apparently, rogue geraniums from Guatamala and Kenya carrying deadly disease have infiltrated the US. To combat this ever increasing threat, Homeland Security (really) is executing thousands of flowers. In Anchorage, this means the greenhouses that used to "overwinter" geraniums are on alert to stop the little terrorists(apparently people pay for geraniums to be babysat all winter?).

"You can't ask a geranium where it came from."
