Picture says it all.
Afternoon shower lasted for about 10 minutes on the 26th April 2013, even though we had a nice morning.
As plants are just coming to life after a cold Spring, there wasn't too much soft foliage damage (I've seen Hosta leaves shredded in the past)
Flowers of the Magnolia stellata have been bruised and some tulip flowers are now peppered with brown spots.
Maybe this is the last throws of Winter?
