Flitterbloom is a magical plant that apparently has long, swaying tentacles. It bears a superficial resemblance to the deadly plant Devil's Snare, but it is harmless, so much so that wizards and witches keep it as an indoor plant or grow it in their gardens.

Miriam Strout, a Healer at St Mungo's, mistook the potted cutting of Devil's Snare sent to Broderick Bode at Christmas 1995 for Flitterbloom.

Georgina Smyth wrote in to Toots, Shoots 'n' Roots asking how she should treat a Flitterbloom that she hadn't watered in months.
