Make a garden for your windowsill by taking cuttings from your favorite indoor and outdoor plants, and root them in water.
Prepare the cuttings by stripping off the lower leaves and cutting off the bottom of the stem. Place in small containers on the sill for a decorative effect. Change the container water weekly to keep the water clear and bacteria free. Plant in soil when the roots are well-formed. Cuttings should be watered when transplanted but not again until soil is almost dry.
