Clover

A clover was a small green plant which typically had three leaves. Finding a four-leafed clover was considered to be lucky. (COMIC: Triskaidekaphobia)
The five-leaf clover was a type of clover which was sought after by Irishman Pat Kelley. Kelley travelled aboard his spaceship, the Emerald Isle, to the planet Skaro where he bluffed the Golden Emperor into allowing him to stay in the Dalek City where he could look around. Upon meeting with the Emperor again, Kelley complimented him on their hydroponics chambers and made special note of their clovers. (PROSE: The Five-Leaf Clover)
