Bellfower 
 
Spring & Summer Flowering, 60cm x 45cm
 Narrow and pointed leaves are a characteristic of this Penstemon which is one of the parents of some of the showiest hybrids.  The fairly large flowers are inflated, funnel shaped and violet to rosy-purple.  This is a very variable plant and so colours may drift to either side of the given spectrum. Sun and good drainage.Mexico.
