As Hoya latifolia ages it flowers in greater and greater quantity.  I have literally picked up hundreds of individual spent flowers over the past few weeks.  These large snowball peduncles of blooms are shown here next to a tape measure, and look like they are around 4 1/2 inches (11.4 centimeters) in diameter.  They also have an other worldly scent at night that should be experienced.  Also, for your enjoyment, here is a new time-lapse of the blooms opening called Just the Flowers Ma’am!
