Ash trees in flower

Look up at the leafless ash trees and you will see that many of them are flowering.  You may also see the spent male flowers on the ground under the trees, so look down as well as up.

The male and female flowers are similar but occur on different trees - usually.  The tricksy thing about ash trees is that they sometimes change sex, so a male tree one year may be female the next, or even carry some branches of each sex.

Tricksy!
