Eucalyptus has a distinct, menthol-like fragrance and it is a popular herb for home remedies. In the garden, it is most often used as an ornamental and it makes a stunning indoor plant. When growing it indoors, note that eucalyptus is considered a heavy feeder and requires full sun. Highly adaptable to most soils, the main concern is to pay close attention to basic feeding, lighting, and watering needs.
