I am dipping into Braiding Sweetgrass by Robin Wall Kimmerer and, curious to see how it looks, I did a search for “sweetgrass” the first link to show was https://www.gouldings.ie/our-products/fertiliser/sweetgrass-fertiliser/ probably the bots in action.
The Latin name for Kimmerer’s American Sweetgrass is Hierochloe odorata, meaning Sacred fragrant grass https://blackstemplants.co.uk/hierochloe-odorata.html this one is rare in Ireland, and known here as Holy Grass, here’s a post about Holy Grass http://www.habitas.org.uk/priority/species.asp?item=2666 and on Wikipedia https://en.wikipedia.org/wiki/Hierochloe_odorata
We have a type of Sweetgrass in Ireland, known as Floating Sweet-grass
Glyceria fluitans, or Milseán uisce (water sweet) in Irish. Here’s what the plant looks like http://www.irishwildflowers.ie/pages-grasses/g-21.html
Grasses are in the Family, Poaceae
There are lots of grasses in the Glen, I must look out for Sweetgrass when it flowers in the spring, to find it there now would be satisfying. I have been making cordage – a kind of spinning with fingers – from some grasses I gathered there in August, it would be some kind of synchronicity to find out it’s Sweetgrass//Milseán uisce or the other type of Sacred Sweetgrass.
