It one of those that bloom once in 7 years when the moon the night prior is blue and morning mist covers the ground. The bats will them come out from their caves and gently tap the tips of the plant to wake it up. In just few hours buds will form and at exactly 6:43 am when the sun is up the flower will open.
If course it is worth mentioning that they must be planted where there is no goats. The goat smell will stop them grow completely. Don't ask me why. No goats!
Dammit... now I forgot the name...
