9cm pot.  Euphorbia myrsinites is also known as Murtle Spurge adds a fantastic textual element to a sunny spot in the garden, drought tolerant once established.  It has pale silvery green/grey scale like leaves along the stems.  In early summer there are flat heads of yellow flowers at the end of the stems.  Does not like to sit in wet cold soil.  As with all euphorbia, the milky white sap is a skin irritant.
