It was only allowed to flower once here, about 18 years ago and I am still digging out newly grown ones every year.
Are the leaves triangular in cross section? It looks terribly like a Sedge. Carex pendula.
There are about 45 species of Muscari to choose from, plus a few hybrids and named forms on top of that.
Unless of course it is a jackdaw!
All spring bulbs may be fed with a low nitrogen feed once the flowers have finished, but before the leaves begin to wither.
And very nice they are too. Keep rolling!
I use JI No2 for alpines as they do not like too rich a soil.
Scilla biflora alba
All taken today!
And some more!
Have some Spring bulbs, mostly.
