A mix of textures
In areas that are bright but receive no direct sun, the large blossoms of tuberous begonias make striking container plants. The round blooms contrast well with the spiky variegated leaves of common spider plants Chlorophytum comosum). The tiny leaves and blooms of 'palace blue' lobelia add a third texture and dimension. Lobelia may go dormant during the heat of summer but will perk up when temperatures cool.
Let the container get barely dry to the touch before watering. Add a slow-release fertilizer to your potting soil, or fertilize about once a week with a liquid bloom booster.
