First flowering grass

When you are in the limestone area of Yorkshire, the first grass of the year to be noticed is the Blue Moor grass---Sesleria caerulea. This flowers from early March and whole hillsides can be turned blue; it is quite striking in its electric blue colour and anyone not familiar with grasses will wonder what plant it is. I do not know of any records in the Calder Valley as it is strictly a plant of limestone strata.
