Aloe vera are grown naturally in Africa and the Mediterranean, so they are used to a warm growing climate. In areas that experience cold winters the aloe vera plant can be kept as a houseplant or in a pot outside that is brought inside during the cold months. There are almost 250 species of aloe vera, but generally all have the same look. The aloe vera plant is green, which can vary from dark to a yellowish-green.
Some aloe have white markings on them as well.
If kept in a warm environment the aloe vera plant can even produce yellow or orange flowers, but this is rare for aloe plants that are kept inhouse. Taking care of an aloe vera plant is quite simple. They do not need a large amount of care and if a person forgets to water them it is actually a good thing for this plant.
The aloe vera plant needs soil that is well drained, like a light mix of part potting soil and another medium. It should be kept in a sunny location when inside and in sun or partial sun outside. The main problem with growing an aloe vera plant is usually over watering. It is easy to tell when the aloe vera plant has had too much water as it becomes dull in color and the leaves become very soft.
