Kūmarahou (Pomaderris kumeraho) is a shrub endemic to New Zealand used in rongoā (traditional medicine). While studying the antimicrobial properties of kūmarahou, we isolated a new strain of Pseudomonas fluorescens, which we designated KF1 (for "kūmarahou flower 1"). Here, we report the complete genome sequence of P. fluorescens KF1.
