Some plants use their roots to spread and occupy more and more space. This is a special case. The shoots that develop in such kind of reproduction are in fact the same original plant - they are genetically identical. However this strategy may result in interesting situation when very big territory will be consumed by single plant which will look like many individual plants unless you bother to check their root system or DNA. The biggest and oldest plant on the Earth is not the huge sequoias or ancient araukarias but the Aspen colony in Utah which cover more then 43 hectares and claimed to be more then 80000 years old!
