The inside surface of the flower tube is heavily spotted.
The plant is frequented by bees, which climb right inside the flower tube to gain the nectar within.
The flower tube is 3-12 mm and is narrowly cylindrical to campanulate.
The flower tube is slit down one side and there are five long blue petals that stretch out like a hand.
Once the hollow flower tube starts to emerge, the flowers will follow shortly.
As soon as the flowers start to fade, the flower tube should be cut off, but the foliage must be grown.
At 7-15 cm long Passiflora mixta has a hypanthium - otherwise known as the flower tube - with a base that contains nectar.
Two upper petals and a lip below form the flower tube.
The flower tube is 13 mm long, tubular at the base and lobed at the tip.
The mouth of the flower tube is surrounded by knobby projections of the sepals.
