Goodyear’s Florist provided flowers to the Royal Court as well as the general public (and Oscar Wilde). It was one of the original companies to set up store in The Royal Arcade, which opened in 1879 and still maintains its original Victorian glass-covered shopping experience today.

The green carnations were worn at the opening of Wilde’s play, Lady Windemere’s Fan, which premiered in February 1982 at the St James’s Theatre, London. The British Library has a copy of the programme.

Read The Guardian newspaper’s review of the premiere.

Robert Hichens wrote The Green Carnation, published by Heinemann, 1894. It is a satire based on the relationship between Oscar Wilde and Lord Alfred Douglas, and infuriated Douglas’ father, the Marquis of Queensberry. Read it at Project Gutenberg.

Read for yourself the controversial card the Marquis of Queensberry left for Oscar Wilde at his club (the Albemarle Club). Opinions vary as to the exact wording on the rest of the card, but sodomite is misspelt “somdomite.”

Famous Trials has a cartoon from a newspaper of the infamous trial.

Reading (a town in England, pronounced ‘Redding’) Museum has pictures and information about Reading Gaol, built in the Victorian era (modern/US spelling: gaol=jail), some from the time of Wilde’s incarceration.

Project Gutenberg also has downloadable/online copies of De Profundis, the ‘letter’ Wilde wrote to Douglas while in gaol, and his poem The Ballad of Reading Gaol, written after his incarceration, during his exile in France.

Wikipedia can introduce you to the Rev Stewart Headlam, the controversial reforming priest who helped to bail Wilde.
