Welcome, JoMama! I see you are in eastern Oregon - perhaps your soil is too alkaline for blueberries? What varieties have you tried? They also like tons of water, I keep mine on a soaker hose and I live on the wet side of the Cascades.
I want to live in a world where the chicken can cross the road without its motives being questioned.
Name: Lauri N Central Wash. - the dry side (Zone 5b)
Looks like Oregon grape?- They do look great! You don't see natives used that frequently in parking lot landscaping which is a shame because natives usually seem to thrive with little attention.
