Hebe Marie Antoinette (Hebe hybrid) is a small evergreen shrub which has narrow green leaves and masses of mauve purple flower spikes that fade to white from Summer all through Autumn. 

Hebes are a very tough drought hardy shrub that have a dense growth habit, making them excellent for hedging or growing as a highlight in amongst the garden bed. They are also very good for pots as their structure and form as well as their very long flowering season makes them very attractive for most of the year.
Prefers a full sun to part shade position, will tolerate dry periods in Summer but performs best with regular watering..
