The number is listed as GARDEN and is linked to Gardens Alive, though this is just one of the companies affiliates - The company is behind a number of additional catalogs and online shops then this just one, so if you get a call and wonder 'why'd I order something from a gardening company?' call back and ask for a order confirmation and what catalog it was from.
The number concerned me at first, thinking someone had put a order in under my name, but it was a item I'd ordered - It was just from one of their affiliate companies.
