Those are gorgeous 😄 Reading it, you're probably right that someone might have thought of making the community vibrant with some seeds. It's helping those pollinators thrive as well. Taking the less travelled path, surprises surely awaits and that was exciting. If I remember it correctly those white ones are royal carpet. I have those plant here in purple and they're beautiful, doesn't need much attention they reseed as well so more flowers for the lot. 😄 If I am the land owner, I would most likely be happy seeing that my vacant lot came to life with the beautiful wildflowers helping the bees.
