Blooming white flower on Lily like plant

Meet:

Spider Lily.

This is the flower which is so much at peace. Actually it is from the family of Amaryllidaceae.
Search on google remained inconclusive. 
Shall ask gardener.

No need. It is called Spider Lilly. Very aptly named.


This plant is very common but the flower actually distinguishes them.
