Growers of Mushroom is the premier album of Leaf Hound, a British hard rock band. The vinyl for Growers of Mushroom has gone on to be very highly-sought-after. A copy in mint condition sold for $4,239 in March of 2016, while a VG+/VG+ copy sold a year later for $6,250. Growers of Mushroom was voted the most collectible rock album by Q Magazine subscribers.

The album, with nine tracks (later twelve, in 2005) was the last that Leaf Hound would release for a while. Leaf Hound disbanded just a few months after recording Growers (which reportedly took just eleven hours to record). The band reunited in 2004.
