Hmmm? Could be the species Epiphyllum oxypetalum aka Night Blooming Cereus

There's a large cactus that blooms only at night (outside the house
here, big white beautiful flowers over 6 inches long). Not sure what
type of cactus it is but perhaps it's the same thing but a bigger
variety?

Coffee grounds and banana peels seems to help it out (seems to make
some extra blooms within a month).
