'Annei' rubra is a C. glauca hybrid that can trace it's ancestry to France & the late 1800's .. the 'rubra' in it's name is reference to the 'red/burgundy' tones in the foliage & stems not the flowers. There is also an 'Annei' with red flowers, but has another name again!
and I have recently found it on an old property in Qld .. more news, later! (no pics yet, sorry)

Dianne, rather than having this great informative comment and images just attached to your photo above, please add it to the entry itself. That way it's visible to everyone looking at that entry.
