In addition to the good qualities you listed, they are also good indicators of compacted soil (plants with thick taproots tend to spring up in compacted soil).

They are technically invasive where I am (northeast US) but I have never seen them take over an area so much as to choke out native species. I would argue that they have become naturalized.
- goda90 3y agoAs far as I can tell, in the US they are only considered invasive in Oregon and Alaska. Invasive is a separate definition from non-native. An invasive(native or non-native) has to be a threat to the established ecosystem, which dandelions generally aren't.
