I have always grown ferraria in pots, so I never see them all over. they do tend to go deep down into the pot that after 3 years I have to dump the pot and restart them. If anyone needs some I have tons this year. Email me privately. Also Belladonna to manage them I don't hand or sprinkler water them, they only receive rain fall. I live in Southern California. Oxalis is invasive but if you don't like seeing dirt in the winter time then scatter some of these bulbs around the foliage is pretty and the flowers well put a smile on your face they are so cute. By summer they completely die back.
