Variegated African Candelabra, Euphorbia Ammak variegata.  Detail of the spines.

Whenever I'm photographing nature, I have a kind of dual personality.  The scientist in me is interested in seeing and learning about new things.  The artist in me is more concerned with visual impact.  I'm focused on things like color, shapes, patterns, light and shadows.  This detail of the ruffled spiny edge of a tall euphorbia is a crude attempt at finding a way to emphasize the graphical elements that most appealed to me, using the limited set of filters available to me.  It was easy to settle on monochrome rather than color, but harder to bring out details of the spiny ridge and leave the background muted.

You can see a bud beginning to form.  I hope I get to see it bloom.

I wonder what the trick is to getting one's jade plant to bloom profusely?  I never got any jade plant I grew to bloom, though I had some for many years.  I love the pale pink and lavender tinges to the blossoms, echoing the rosy blush around the edges of the leaves.
