There is a flower seed selling company called American Meadows. They sell the seeds in 4 or 5 groups and they have a large northeast section.
I think summer flowers are living their final bloom and you will arrive to the last flower covered fields. There are many mountains at the north of the NE and MtRainier is the only I know. The fasted wind recorded there , 200 mph. There are lots of beers and bees there. May be you can spend a summer in the fire watching post , under the clear star filled skies and the big mountains deep black and fills your room with their silhoutes. Or you can visit a pakistani deli and eat chicken with your hands
