Hey guys, Customer of mine has a nice shade garden but she wants more color in it. It is almost full shade- the northern side of a house. What are some plants that are either colorful in their foliage or flower in the summer/ fall that can do well in shade? I have already thought of dwarf fall blooming camellia and huechera. Will nandina 'firepower' turn red in the shade or will it stay green? What is that dark red / purple shrub I see everywhere with thorns? THANKS!
