“Cauliflower is just ghost broccoli” is a saying that has been printed on many images. The saying is based on cauliflower’s color (usually white), that both have edible flower buds, and that both are from Brassica oleracea. There are many differences between the two, however.
   
“Does purple cauliflower taste different from regular cauliflower? I call cauliflower ‘ghost broccoli’ because I feel it lacks flavor” was posted on the newsgroup alt.polyamory on July 1, 2005. “@eskamo9 >cauliflower is like ghost broccoli” was posted on Twitter by softmode on September 25, 2011. “Cauliflower is just ghost broccoli” was posted on Twitter by Nicolas Kipling on November 24, 2011. “Cauliflower is just Ghost Broccoli” was posted on Reddit—Showerthoughts on May 17, 2018.
   
A viral joke was posted on Twitter by Roxi Horror on August 2, 2018:
   
FRIEND: It’s called cauliflower. It’s not ghost broccoli.
ME: [taking a long drag on my cigarette] Listen kid, I know what I saw.
           
“Cauliflower is just albino broccoli” is a similar saying. “As far is differences go, cauliflower is actually just an albino broccoli…jokes! It’s not. Though they are quite similar, the edible flower buds I mentioned are more spaced out in broccoli. Cauliflower has less calories and carbs, while broccoli has more vitamins and minerals” was posted on Live - Eat - Learn on November 18, 2019.
     
     
Wikipedia: Cauliflower
Cauliflower is one of several vegetables in the species Brassica oleracea in the genus Brassica, which is in the Brassicaceae (or Mustard) family. It is an annual plant that reproduces by seed. Typically, only the head is eaten – the edible white flesh sometimes called “curd” (with a similar appearance to cheese curd). The cauliflower head is composed of a white inflorescence meristem. Cauliflower heads resemble those in broccoli, which differs in having flower buds as the edible portion. Brassica oleracea also includes broccoli, Brussels sprouts, cabbage, collard greens, and kale, collectively called “cole” crops, though they are of different cultivar groups.
 
Wikipedia: Broccoli
Broccoli is an edible green plant in the cabbage family (family Brassicaceae, genus Brassica) whose large flowering head, stalk and small associated leaves are eaten as a vegetable. The word broccoli comes from the Italian plural of broccolo, which means “the flowering crest of a cabbage”, and is the diminutive form of brocco, meaning “small nail” or “sprout”.
   
Broccoli is classified in the Italica cultivar group of the species Brassica oleracea. Broccoli has large flower heads, usually dark green in color, arranged in a tree-like structure branching out from a thick stalk which is usually light green. The mass of flower heads is surrounded by leaves. Broccoli resembles cauliflower, which is a different cultivar group of the same Brassica species. In 2017, China and India combined produced 73% of the world’s broccoli and cauliflower crops.

Does purple cauliflower taste different from regular cauliflower? I call cauliflower “ghost broccoli” because I feel it lacks flavor.

If cauliflower is just ghost broccoli and broccoli are just tiny trees, then essentially cauliflower is a bunch of trees after they are made into the things that come from trees.
