The Citrus 'Calamondin' provides a tropical atmosphere in the garden and a wonderful fragrance. The calamondin tree blooms in the spring with lovely white flowers. Two years after planting, you will see the fruits hanging from the tree. However, the fruits are only decorative and are not for consumption.    
The citrus tree flowers best in a spacious planter in a sunny yet sheltered spot. It's important to water the tree straight away after planting. After that, don't water it again until the soil feels dry to the touch.    

Remember that it needs to spend the winter in a spot where it will be safe from frost.
