Erica x williamsii (Erica tetralix x Erica vagans) is another group of useful summer flowering hybrids.  They seem to be tolerant of varied soil conditions including alkaline soil and are seldom damaged by cold weather.  Useful as ground covers and feature attractive bright golden tips in early spring.  These plants are terribly under utilized in the United States. 

 

Zones 5 (-20 degrees) or warmer.
