Adrian Slack is an author and authority on carnivorous plants. He is the author of two books: Carnivorous Plants (1979, 2005) and Insect-Eating Plants and How to Grow Them (1986, 2006).
Both of Adrian Slack's books are considered to have excellent cultivation information and are highly regarded in the carnivorous plant community. After a long time out of print, both of them have recently been reissued. Slack has developed hundreds of cultivars and many have been named after him. The sundew species Drosera slackii was named in his honour.
Slack was featured on a 1981 episode of Nature Watch and in an accompanying book published the same year.
