This is known as the Thistle Pattern by Buchan Pottery and is one of the most popular patterns.  This pattern would feature a thistle, heather, and bluebells to name a few, and all were on a sky blue background.  This dish has those three flowers and two others (see photos).
This dish is divided into 5 areas (see photos).  It is marked on the bottom, but hard to read (see photos).

This dish measures 11.50" round.

There are no chips or cracks.  There are some bumps on the back under the glaze from production (see photos).
