Geraniums are wonderful plants. They are tough, drought resistant, that means they don’t die when short of water. They have nice simple flowers and produce those flowers year round. However, they are not known for being tidy. They just grow where they want and are not really know for being graceful.
Still as tough plants, they will last years and years as long as you protect them from frost.
This is the mess of the plant that these came from. It was sitting in the corner of the classroom by the whiteboard most of the year, so an old friend for you!
