For the big one you will be a bit limited for colours by the shade. Will you be watering them? Because there is dry shade and damp shade which can suit different types of plants. In shade it can help to have foliage shape texture and colour. Plants - Hostas, Astilbe, Brunnera "Jack Frost", Pulmonarias, hardy Fuchsia such as "Lena", Epimediums, Heucheras, Primulas, Astrantia, some of the hardy geraniums.
