Dianella Cassa Blue® 140MM

Dianella caerulea 'DBB03' 'Cassa Blue®'

I am Dianella Cassa Blue®. My family originated from Eastern Australia.

Habit Strappy - Long flowering
Plant family Asphodelaceae
I am a compact native plant with stunning blue foliage that can be enjoyed all year round. I produce masses of purple and yellow flowers from September through to November followed by bright blue ornamental berries. I can be mass planted in many garden settings, including alongside paths and driveways. Hardy I am both tolerant of drought and cold. I perform best in a full sun to part shade position in well-drained soil. I need very little maintenance, however, to keep me looking at my best remove my older leaves as required or cut me back halfway every 3-5 years.
Caution: Berries harmful if eaten
