Decorate a windowsill
Windowsill flowers do double-duty by brightening a home's exterior and adding the scent of fresh florals into the home.
If you're after a monochromatic look, consider using Martha Washington geraniums, licorice and trailing calibrachoas. This can be very striking, especially in a larger planter. Try accenting it with other thirst-defying plants like pansies and petunias. Alternatively, if you're after a bright and dramatic effect achieved by intense and complementary colours, Peg says that geraniums, petunias and coleuses can be found in any colour desired and are good, no-fail basics.
“Anything can go in a larger container on the patio or in the yard, but smaller flowers might get lost or crowded out by a bigger container,” says Peg. Use your window box to make the most of the smaller staples. Plants with larger flowers or leaves that will be seen from farther away are always a good choice. Note: Beware of watering needs. The shallowness of smaller containers means you will need to water more frequently, so it's best to use them for housing drought-resistant plants.
