I have never seen the frost curls with this plant in the autumn as another species with the same name puts forth. I regularly find the flowers in Quabbin Park and these get mowed down with the grass once flowering season is over. But, I am pretty sure the other ones give some frost curls from their cut stems so am not sure why these don’t unless the name comes from some other phenomenon.
At any rate, these are always a joy to find with their soft creamy hue and the nice arrangement of petals.

I was a little disappointed as I often find Yellow Star-grass-Hypoxis hirsuta nearby but none this year. There is still time. And, yes, it is also misnamed. While the leaves do look like grass, it is actually in the lily family. At least it is yellow. If you are curious, here is a post from 2015.
