Clock vine

What beautiful flowers and a great colour

The flowers do resemble (slightly) the pendulum of a grandfather clock. Though, I don't know if that is the reason they were named.

They were very pretty Tina2 and must be very sweet too, because the flowers were covered in ants. The vine is growing indoors at San Francisco's Conservatory of Flowers. I just copied what the sign said Marguerite, so I am not sure why we call it 'clock vine' here. Gardengnome has a good thought as to why :) I liked how the flowers hung from what looked like a thread.
