More problems with Second Garden

My wife and I created a garden in the back that has a problem. See pics.
My wife created this memorial garden (ok, she chose the plants, I did the digging.) which sits against the neighbor's fence. I note that this is in direct flow from the neighbor's downspout, which floods this area when it rains. We expected the plants to get plenty of water during rainy seasons, but it would run off, downhill (a 20% grade, it covers the whole back yard. This is the only level place for a garden.)

We did this June 18. I dug out the grass and moved it. We then put down some good garden soil the plants went into the ground the same day. (also used weed fabric and mulch on top.) There were some torrential rains this last weekend, but all the plants had been watered regularly before that day .

The last two days, we discovered our butterfly bushes were dying. My wife is quite knowledgeable about plants and this is just foreign to both of us. You can see that all the other plants are doing well, it's just the butterfly bushes that are not. (We put in a butterfly bush in our other house and it grew tremendously. It got over 6 feet tall, and was at the end of a downspout.)

Looking for some ideas of what could be causing this.

Garden is approx 8-10 feet across the front. All the other plants are doing well, it's only the two butterfly bushes having issues.

Neighbor's downspout there in the side of his yard. You can see the green path of the water.

Over watering would be my first guess. Butterfly bushes are very drought tolerant but can't handle too much moisture and like well drained soil. If planting them there I would consider mounds to get them above the runoff water and into lower moisture soil.

Also, your butterfly bushes are planted way too close together. One adult plant alone could take that entire bed.

too much moisture
We had a butterfly bush at another location which seemed to get as much if not more water, but honestly, I'd go with anything right about now. My wife is beside herself over this. We will see about replacing them with something else. perhaps we can put the butterfly bushes elsewhere.

The fence is reflecting additional heat from the sun. Partial shade to give the plants a chance to get established will help.

Dig them up and put in pots where you can observe sun and water. Plant something else in their locations.
