Don't worry, most plants will adjust to the constant light but evergreens will do better than flowering plants. Looks like it is in the shade (I see a happy hydrangea in the corner of the photo you sent) so I suggest the dwarf Pieris japonica and the variegated euonymus fortunia winter creeper both evergreen with white bits on the foliage. Add some golden tulips and dwarf daffodils for spring color. It will be lovely. Keep growing, Marianne Binetti
