This picture was taken in a private garden in Bogota, Colombia by a friend who comissioned me to do a digital painting of it to give as a gift to the owner of the house.

It was a very ordinary looking snapshot - and it had a hand behind the yellow blossom holding it up for the camera - so I had to do a bit of Photoshop magic.

The experts at Dave's Garden identified the flower for me.

This exotic Mexican bulb is sometimes called peacock flower, an appropriate name in view of its quite startling colour combinations- all the shades of scarlet, orange, pink, yellow, mauve and white, usually with contrasting markings. It is barely hardy, and normally grown as a tender summer annual, planted in spring and dug up again in autumn for storing in a dry frost-free place. It needs all the sun available, as this not only encourages flowering but also ripens the bulb to ensure a similar display the following year.
