Photo - Evergreen Pear (Pyrus kawakamii)

This small tree is neither evergreen nor bears any pears.
But it is covered with small white flowers every February
 here in San Diego.  The blooms only last a month and
then the leaves comes in.  In San Diego, Evergreen Pears
can become infected with a virus known as fireblight.
Fireblight is spread by bees and causes the branches to
have a burnt look.  The key to stop the infection
from spreading all over the tree is to remove the infected branches
in the Winter before the blooms and bees arrive.
