I seeded four types of native clover and some native lupines based on the recommendations of a local professor at the university.
They took a little while to start thriving because kids and dogs kept churning up the dirt and mud, but its starting to take hold. Much greener and more widespread, and softer, than the native grass seed I planted at the same time. It seems to be helping the grass to take hold in the same areas too. We had a solid two weeks where we couldn't walk outside without getting mobbed by butterflies and other pollinators. Its nice to feel like I'm just dumping water onto my lawn for no reason.
10/10 would recommend.
