On May 2, 2018, it was announced that DC Universe had given the production a script-to-series order. Mark Verheiden and Gary Dauberman were expected to write the first episode of the series and executive produce alongside James Wan, Michael Clear. Rob Hackett was set to serve as a co-producer. Production companies involved with the series were slated to include Atomic Monster Productions and Warner Bros. Television. On September 4, 2018, it was reported that Len Wiseman would direct the series' first episode in addition to serving as an executive producer.
Despite being released on DC Universe, the series does not exist in the same fictional universe as the service's other live-action series, including Titans and Doom Patrol. On June 6, 2019, the series was canceled one week after its premiere aired. Before the series' cancellation, there were plans for a three-season arc and to introduce Justice League Dark and create a spin-off based on that team.
In September 2018, it was announced that Crystal Reed and Maria Sten had been cast in the main roles of Abby Arcane and Liz Tremayne, respectively. Jennifer Beals was also announced in the recurring role of Sheriff Lucilia Cable, although she would later be revealed to be part of the main cast. In late October and early November 2018, more series regulars were revealed, with Jeryl Prescott cast as Madame Xanadu, Virginia Madsen cast as Maria Sunderland, Will Patton cast as Avery Sunderland. Andy Bean cast as Alec Holland with Derek Mears as the Swamp Thing, Henderson Wade cast as Matt Cable, and Kevin Durand cast as Jason Woodrue.
Also in December 2018, Ian Ziering joined the cast in the recurring role of Daniel Cassidy / Blue Devil, and a month later, Leonardo Nam was cast as Harlan Edwards in a recurring role.
Principal photography for the series commenced in early November 2018 in Wilmington, North Carolina and wrapped on May 6, 2019.
On April 17, 2019, it was announced that production for the series had been unexpectedly cut short due to creative differences with DC Universe's parent company WarnerMedia, thus reducing the original episode order from 13 to 10 episodes. Further reports stated the series had been canceled due to budget shortfalls after the expected level of tax rebates offered by the state of North Carolina were substantially reduced. A representative from DC Universe stated that the streaming service was being re-evaluated and that there were no plans for a second season. When asked why specifically the show was canceled, the spokesman responded, "Unfortunately, we are not in a position to answer at this time."
Mears described the cancellation as a "heartbreaker" and felt the decision to cancel the show showed a "lack of respect" on DC's part. He added that members of the production had been told up until the cancellation "how amazing everything was... So it's a weird nebulous space that we're all in now because we don't know officially why that would happen, or why they canceled it." In mid-2019, a movement with the hashtag #SaveSwampThing began spreading on social media shortly after the series was cancelled in an attempt to save the series. Mears also showed his support of the movement. With The CW network acquiring the broadcast rights to the series, The CW president Mark Pedowitz did not rule out the possibility of renewing the series for a second season, saying, "that would be a discussion for Warner Bros. and the CW. But at this time, Swamp Thing is just the episodes we have." In January 2021, Pedowitz said it was unlikely the series would return on The CW but did state there was a slim possibility of Swamp Thing appearing on other Arrowverse series, such as Legends of Tomorrow.
Swamp Thing premiered May 31, 2019, on DC Universe. Despite being canceled not long after its premiere, DC Universe continued to release the remaining episodes of the series, with the finale being released on August 2, 2019. Swamp Thing: The Complete Series was released digitally on December 2, 2019, and on DVD and Blu-ray on February 11, 2020.
In May 2020, The CW acquired the broadcast rights to the series. It began airing on the network on October 6, 2020, and concluded on December 22, 2020.
On Rotten Tomatoes, the series holds a 92% approval rating based on 39 reviews, with an average rating of 7.32/10. The website's critical consensus reads, "By leaning into the horror of it all, Swamp Thing swims deep into the trenches of this strange world and returns with a scary good TV show." Metacritic, which uses a weighted average, assigned the series a score of 69 out of 100 based on reviews from 6 critics, indicating "generally favorable reviews".
