The Flowers of Spring

I showed you one photograph that I took while on my bike ride the other day - it was the mailbox covered with Wisteria.  Thirty minutes later going uphill I saw these Azaleas, and then the white flowers, and then the magenta flowers.  OK, so you can see that I only know the name of one of the three flowers.  I need help again!  Please.  But the photograph is really beautiful, isn't it?  To see these colors surrounded with green leaves is really something.
