Not on roses, actually, but raindrops on the leaves of the elephant ear plant. Raindrops I first spotted a few weeks ago when I was out walking Copper on a moist morning. 

I marveled at the way the liquid pooled on the surface of the giant leaves, thought to myself, you must snap a photo of this.

But I came inside and immediately forgot the impulse. By the time I remembered, it was too late. The sun had warmed the leaves and the moisture had evaporated. 

The artistic imperative strikes when it strikes. It does not linger. Luckily, it rained again.
