I wrote this up in answer to a question on Facebook. The asker wanted to know if there were any flowers specifically associated with Brigit. I thought other might like to read about this, too.
There is a windflower named St. Brigid's Anemone. It is lovely, though it refuses to come up whenever I plant it. It is the conditions of my garden, I suspect, not the bulbs themselves, that are the problem.
This video tells you how to plant them.
While searching just now I came across a variety I didn't know of. The Anemone St Brigid The Governor. I like to think of this as evoking her Abbess days, when she pretty much governed the place.
I don't know how new the St. Brigid Anemone is, but I suspect it is relatively modern.
