Blossoming Questions

What Zone is Tulsa, OK? Will Butterfly Bush survive?
Where should I plant my Vanilla Strawberry Panicle Hydrangeas? I’m in Zone 8a.
I just purchased a 2 gallon Endless Summer. Can I plant this in a raised garden bed? Or a pot and what size?
I have a First Edition Berry White Hydrangea. It’s new and was planted last fall and has beautiful blooms. But it keeps losing leaves. They turn…sort of a very dark yellow…but more brown, really and fall off. It have it on a drip system so I can adjust how much water it gets. I live in Zone 7 and it’s over 100 each day right now, so I am giving the plants on my drip about 20 mins. of water a day. Not sure what to do? It is getting too much or note enough water?
I planted 5 hydrangeas and two have green wood beneath the soil, two have each one green leaf sprout. My fifth shows no sign of life! I did not cut wood down as they are only 12 inches as these were new plants – I do not see anything happening on the old wood. The buds are hard and dark brown (look dead) – they get morning sun until about 1 pm then are in the shade for the rest of the day – soil is moist but not wet and I’ve added fertilizer—is this normal for June? What else can I do to make them thrive?
I NEEDED TO REMOVE TWO LARGE PURPLE-LEAVED BUSHES FROM ALONG THE WALL OF THE SOUTHERN FACING SIDE OF OUR HOME. THEY WERE PLANTED ON OPPOSITE SIDES OF A LARGE SILVER-LEAVED WHITE POM POM BUSH. THE REMOVED DYING BUSHES WERE APPROXIMATELY 10 ‘ TALL AND 15’ WIDE. I’D LIKE TO REPLACE THEM WITH SOME TYPE OF SHORT EVERGREEN PAIRED WITH SPRING/SUMMER LONG BLOOMERS. I HAVE IRIS, PEONIES, AND HOSTA PLANTED ALONG THE PERIMETER OF THE GARDEN. ROSES DO NOT DO WELL FOR ME. THANKS FOR ANY HELP!!
WHAT TYPE OF PERENNIAL CAN I PLANT IN THE SHADE THAT’S LOW MAINTENANCE AND DEER RESISTANT?
LOOKING FOR A DEER RESISTANT SHRUB IN ZONE 8 FOR PARTIAL SHADE. PLEASE HELP!
