According to the info, you'll need a Dracula costume to pollinate.
They're pollinated by bats.
"Vell now! Wasn't dat fun! Making vit da pollen in da night...by moonlight...vid my bud Renfield!"
"Childrens of da night! Vat music dey make!"
MMMMM...Upon further study.. it was found this flower wasn't mearly reflecting the ultrasonic signals from the bat... but was found to be the source of ultrasonic signals they believe were broadcast to the bat.. signaling to it the possibility of a meal and great sex.. in the hopes the bat would fly by and assist in it's pollination
amazing adaptations from these plants... over these millions of years..
