Answer: It is very difficult to grow things around the roots of a silver maple tree, I know...I have one. Dry shade is also a challenge for gardeners. There are some shade loving, drought tolerant perennials to try: Alliums, Arabis, Artemisia, Aruncus, Baptisia, Echinacea 'Magnus', Festuca, Helleborus, Hemerocallis, Lamium, Monarda, Penstemon, Sedums, and Tovara. Keep trying to amend the clay soil with organic matter such as compost, leaf mould, and composted cow manure. This will help whatever you plant there have a better chance of thriving in those difficult conditions.
