Our “Biodiverse” Lawn

Our “lawn” would be outlawed in most of the Twin Cities’ tonier suburbs.  But living in the city allows for a little more variety.  Twenty years ago we sodded our yard after building an addition.  The grass was perfect — pure, uniform blades of healthy green.  We kept it that way for a couple of years, then quit using chemicals when our son was old enough to play in the yard.

First a few common violets dotted the grass with their subtle, delicate blooms.  Then dandelions showed their bright heads —miniature globes of sunshine that blossomed into balls of fluff.  Our son loved to blow the fluff, watch the seeds dance on the breeze and settle into the grass (to grow the following spring).

Over the years, seeds from garden Siberian squill and striped squill spilled out into the lawn during heavy rains.  They popped up in all parts of the backyard along with three other species of violets.  These spring blooms are lovely and welcome, but the plantain, chickweed and crabgrass that appear later in the summer?  Not so much.

One afternoon our neighbor, Steve, an environmental engineer, stopped to chat while I was digging out dandelions.  I bemoaned the state of our lawn.  Steve looked at it for a minute, then said that he thinks of it as a biodiverse lawn.  The variety of blooms, though they are “weeds” in the eyes of most people, provide a great source of nectar to native bees and other pollinators.  The insects and worms provide food for birds, chipmunks and many small critters.  In comparison, Steve said, our former uniform lawn was a “dead zone” with little life beyond the non-native grass.

I still miss our perfect lawn when I look at the lush, tidy, green grass on our block, and every summer I’m tempted to use chemicals to restore ours.  But, I ignore that urge and instead, we mow the “grass” down to a short patch of green turf that is alive with birds, insects and other creatures — and that also looks  acceptable to our neighbors!

  1. Hi, Beth

    I’m glad to know that our lawn type has a name! Right now, we have more violets and other plants than grass, too.

    Love, Sue

  2. I have violets in one corner of our lot and it’s become my favorite corner. It takes a lot of weeding to keep out the creeping charlie but over the years I’ve welcomed numerous volunteers including columbine and solomon’s seal. I even have irises in there – probably from the neighbors nearby compost pile. I think of it as a true garden.
