On angels' wings

I've learned that there are 1300 species of begonias and 10,000 cultivars!  This means it is going to be impossible to accurately identify the specific one I have growing in my backyard.

I received this plant as a cutting from a friend.  It seems to be a variety of angel wing begonia.  These begonias grow on cane-like stems with wing shaped leaves and pink-to-red drooping blooms.

I've never been very good at growing the more exotic-looking begonias.  I always seem to either drown them or starve them to death.  In all honesty, I was going to throw this one out in despair  . . . until it bloomed.  In spite of its leggy appearance, the blooms delicately suspended between this angel's wings bring joy to my heart.  

I'll keep trying.
