Cordyline indivisa Blue Dracaena, also known as Broad-leaved Cabbage Tree, Mountain Cabbage Tree, or Toi, is a distinctive evergreen tree native to New Zealand. It is characterized by its broad blue-grey leaves and compacted inflorescence that emerges from beneath the foliage.
Growing up to 8 meters in height, with a trunk diameter of 40-80 centimeters, Cordyline indivisa forms a stout, unbranched tree. The leaves measure 1-2 meters long and 10-30 centimeters wide, drooping with age and exhibiting a blue-green color with a prominent red, orange, or golden midrib.
Cordyline indivisa is not considered threatened, although certain populations have experienced reductions due to livestock and goats. The tree prefers cool, moist soils and semi-shade, making it suitable for cultivation in cooler regions of New Zealand. However, it has a tendency to collapse during high temperatures or water shortage.
In terms of its culinary uses, the root of Cordyline indivisa can be baked, while the soft and starchy pith of its trunk is dried and steamed to make porridge or a sweet drink. The plant's root and stems are also rich in fructose, making it comparable to Sugar Beet (Beta vulgaris altissima) in terms of yields.
Please note that Cordyline indivisa should not be confused with Cordyline australis, as the former is mistakenly sold as Dracaena indivisa or Cordyline indivisa, despite being an immature form of Cordyline australis. This confusion arises from the fact that Dracaena is a closely related genus that has undergone reclassification as Cordyline.
Overall, Cordyline indivisa is an attractive and distinctive tree with unique features that make it a valuable addition to any garden or landscape.
