This red/purple cotinus on our deck (variant rhus cotinus) and its largely spent flowers become particularly attractive just after rain, and we’ve had a lot of rain lately. Not good for most photography, but great for raindrops!
Rhus Cotinus is also called ‘European smoke bush’, presumably because the large groups of flowers on stems can look a bit like a smoky edging to the plant (see above Wikipedia link).
Note to pedants. No they’re not the actual rain drops, but the varied effect of splashes, joining together, streaming, viscosity, surface tension, etc! That’s why some of the drops are rather large and some are very small.
