Answer: The site you describe should be considered a shady one. Because the silk tree leaves are finely textured, the area probably receives filtered sun/shade. Plants that thrive under these conditions include Abutilon (flowering maple), Aucuba, Enkianthus, Euonymus, Fuchsia, Gardenia, Leucothoe, Azalea, Acanthus, Aquilegia (columbine), Asarum (wild ginger), Begonia, Caladium, Campanula, Coleus, Dicentra (bleeding heart), Ferns, Helleborus, Impatiens, Lilium, Lobelia, Myosotis (forget-me-not), Oxalis, Saxifrage, Vinca and Viola (pansy). There are many, many others, but the above list should provide seasonal color under your silk tree.
