What I wrote was that we call certain plants weeds because they have a habit of prolific reseeding and thus will crowd out other plants that we prefer, be it prettier flowering ones or edibles. The word 'native' wasn't used by either of us.
One of my revelations as a new gardener was discovering how many of the prolific plants in green spaces aren't native to the area and often are culprits in terms of reducing biodiversity because they don't support the native insects, lepidoptera, and ultimately that effect works its way up the food chain to the bigger animals like coyotes and deer. Eucalyptus trees are an iconic feature of northern CA woods but they're not native and many are highly flammable, which makes them a poor choice for a state with an annual wildfire season. Fennel, broom grass, and other non-native grasses dominate the open spaces and none of them belong here.
