Miniature Lupine

Description:

A small plant about a foot high with small clusters of beautiful bright blue flowers. I observed what looked like fused keel petals but these were wing petals enclosing the keel. The banner petal had white patches that made each flower look like a little bonnet.
Leaves were palmate with long narrow leaflets and covered with silvery hairs.

Habitat:

Growing in patches on open grassland - Cardinia Reservoir Park.

Notes:

Thanks to Mark for helping with identifying the species.
