I don’t see anyone else around here doing this, but it just gives such a charming result. I use a dibbler (and yes, part of the pleasure of doing this is getting to say dibbler) to poke holes in the grass, and slip little chionodoxa bulbs into them — it takes maybe 15 minutes to plant a hundred or so that way.
Then in the spring, there’s a moment when my grass is scattered with little pale blue and purple and pink stars. They generally bloom around the same time as snowdrops, and are commonly known as glory-of-the-snow, but usually the snow is gone in my garden by the time they show up.
No care needed; by the time the foliage starts to yellow, it generally time to start mowing anyway.
