Care & Size Guidance
The Purple Cabbage Tree is smaller than the original species and thus is more suitable for container growth. Specimens grown in a container are unlikely to flower.
Planted in the ground it usually flowers (and thus forks) after about 6 to 10 years, but the right conditions can bring the flowering to 3 years of age.
The ‘Atropurpurea’ cultivar is marginally less hardy.
