Leucojum Aestivum - Summer Snowflakes blooming!

My summer snow flakes or leucojum have a couple blossoms.   There are many more that look like they are sending up flower stalks.  I have never grown this item before - but it appears to be doing well in my garden.  Here's a picture of one of them blooming.  The leaves look like daffodils - but the flowers are nothing like a daffodil.
