Having one flower gets its seeds under another plant can cause issues of competition, even with native plants.

Uhh native doesn’t mean self seeding or self maintaining. Your native plant isn’t native here and does the same exact thing unless it’s invasive…

You claim I’m uneducated and you only spout marketing they sell to people who haven’t read or studied horticulture.

Heres a great resource so you can educate yourself instead of repeating marketing verbatim.

Great point right here for you

Because native plants are uniquely suited to their geography, they are able to grow with little need for human inputs. Natives require less water, fertilizer or pesticides. They simply need to get established and then you barely need to do anything. Apparently non-natives are the exact opposite. They constantly need watered and fertilized. They are always plagued by insects and need sprayed all of the time. If you see a sick or diseased plant in your neighborhood, rest assured, it's definitely a non-native. 🙄
