Have u ever heard a flower call "Fireball Lily"??

It took almost an hour to find the name of this flower in the internet after I realised no information about this one in my  "Tropical Garden Plants" book.

it looks very similar to "Melaleuca citrina" ("Bottlebrush tree" in Japanese) but this one is not a tree, but the stalk look like lily I was wondering and my guess was correct and called "Fireball Lily".
in Wikipedia they call "Scadoxus" (blood lily)", family of Amaryllis.  It's lovely flower - big round ball shape blooming few of them in Cha Cha garden at moment.
