Believe it or not, The Orchid Gardeners actually started out as an Elf team. The Elfs shared not only the love for Blood Bowl, but also a passion for plants and landscaping.
At one time a pack of Orcs showed up for pre-season training, thinking “Orchid” had something to do with the strength of the Orc skin, and that “Gardeners” was alluding to the use of guard on the pitch.
Since the Coach didn’t have the guts to enlighten them (I don't blame him!) and since the Elf players never returned, the Gardeners are a bona fide Orc team ever since.
