I got a great picture of the Mahonia at the park in bloom.  

 

This is Mahonia aquifolium, also called Oregon holly grape.  It is neither a holly nor a grape, that's just the common name.  The leaves look like holly leaves, and the fruits look like grapes.  Don't know about the Oregon part.

 

Mahonia is an early spring bloomer, and sometimes it blooms so early that the flowers get burned by snow or frost.  Those years they bear no fruit.  But when we do get to see the fruits in summer, they are bluish in color, grape-like, and edible.  I've never tasted them, but I'll let you know if I ever get the chance.  This bush has gotten frosted two years in a row.  Maybe, this year we'll get to see the fruits.

 

HAPPY GARDENING!!!
