Lobelia/Pratia pedunculata or Blue Star Creeper
I bought my first small pot of this last year - it is lush! Tiny, china blue starry flowers, atop evergreen, spreading greenery (small leaved). Related to lobelias we all know, but looks nothing like them.
Amazing plant - never gets sick, thrives in heavy soil, in total shade. Whjat more could you ask for really?!
Except that i can't seem to get hold of any more.
I know I should probably just tear a piece off and do my own cuttings, but I never seem to have much success with these...
