The Aloe Vera is a great plant for beginners - it's easy to look after and has medicinal properties, with its sap used to relieve pain from scrapes and burns (not to be ingested).
It likes bright, indirect light and needs a good watering when the soil dries out - ideally, keep the Aloe in its nursery pot to allow the water to drain out, if it sits in water for too long it will suffer from root rot.
Pot width 10cm
Plant height 30cm
Water - Let the soil completely dry out before watering.
