Heliconias are found in rainforest areas and are native to South America and some Pacific Island areas. The flowers are actually small white parts in the middle of brightly coloured, waxy bracts (not visible in my above photo). This Heliconia is nicknamed Lobster Claw for the obvious resemblance. These plants are related to bananas and have similar large bright green leaves. They have similar growing conditions to gingers and Cannas.
For the green parts and surrounding foliage, I've used Spectrum Yellow underneath, then as that has dried, have layered it with Sap Green and Australian Green Gold. For the darker foliage, I've used Pthalo Green and Oxide of Chromium. I've also used brown highlights with Burnt Sienna Hue.
The background is a layer of Pthalo Green with a layer of Payne's Grey on top as I wanted the background to be very dark to make the red of the waxy flower really stand out in a dramatic way.
Overall I'm happy with the overall result and with the colour intensity. Am looking forward to painting some more lush tropical plants soon...
