There are many different species in the allium family. They have a cluster of flowers bursting from the top of a stalk. This picture shows the flowers will spread a little distance from the stalk, however some allium species have a tight cluster of flowers that together look like a single detailed whole.
Photography notes:
The background is a tree-shaded area. The soft light comes from a cloudy sky filtered by the nearby trees. The original image is unmodified except for resizing.
