Watercolour on Fabriano 5, framed in Oak

AVAILABLE – this painting is available for sale through the Open Eye Gallery

An original watercolour painting of Arisaema costatum. I watched this plant grow in my Edinburgh garden for two years before painting this specimen. Depicting two seasons of growth, the inflorescence and leaf from the summer months, and the fruit from the autumn season.

I particularly love the graceful shape to the inflorescence with its long entwining spadix, it is the most graceful of my arisaema flowers and the carmine and white striped spathe is just candy cane delicious. The leaf is edged with carmine which diffuses up the veins segmenting the fresh green elephantine trifold leaflets.  In autumn the lovely orange fruits are held on a curved peduncle that colour morphs from deep chocolate to a banana yellow, this truly is a rainbow of arisaema.
