Help me please! I am new to this! I live in Southern California. I am in the process of transitioning my entire grass lawn to drought tolerant plants. I am planning on planting myoporum parvifolium to cover a majority of the lawn. I see that it is sold by the gallon or in a flat. Which should I plant? I am assuming the flat is a whole bunch of tiny plants? Would each of these branch out to 9 feet? When it says it can reach 9 feet, does that mean radius? I am so lost! Any help is appreciated :)
