Will wormwood deter rabbits from the garden?
Rabbits are not fond of wormwood. It can deter them from the garden, but they can become use to the smell and it stops working.
I live in northern Minnesota and want silver mound as a ground cover. My conditions are not the best. My property is rocky and clay. Can I still grow it and will it survive?
I think silver mound stands a pretty good shot of growing and surviving if you amend your clay soil. Here are some articles that will tell you how:

Silver mound is rated for zones 3-9, you are zone 4 so you are within the acceptable range.

Do you believe that sweet wormwood (or any of its varieties) could be successfully grown in sub-sahara Africa?
Given the proper growing conditions and care, I would have to say, yes. You can also grow this plant in containers if the area is not suitable. Here is more information on growing this plant: https://www.gardeningknowhow.com/edible/vegetables/celery/wormwood-plant-growing-sweet-annie.htm
the silvery gray foliage has all been packed down (I live in the Syracuse NY/Oswego NY area)and is dead looking. Should I cut it back and see if it has survived? Unfortunately I did not winterize it last fall,assuming it would take care of itself...
Yes, prune it back to about 3 inches above the soil surface.

I would recommend checking places like Amazon, Etsy, or Ebay. They will usually have exactly what you are looking for.
We planted out our front garden about 8 months ago and there are some plants that have really thrived (wormwood, lavender, callistemon,) and the other half of the plants in the garden aren't much bigger than when we put them in the ground. They are only about 5m apart and also contain a wormwood and lavender, so the comparison is easy. So what can I do to help this? My husband wants to dig up the poor performing plants, mix in horse poo into the soil, and then replant the plants. But is there a less disruptive answer? Thanks
A few suggestions for you on this. I would rake up the dropped leaves; they can often spread diseases into the soil and your other plantings.
Then I would start with a simple soil test before amending your soil. This will save you time and most likely money to avoid guessing what it may need.
Your County Extension Office will help you with this for just a few dollars in most cases.
