Cordyline indivisa aka Blue Dracaena

Taxonomy

Cordyline indivisa, commonly known as the Mountain Cabbage Tree, Bush Flax, or Tōī in the Māori language, is a rare monocot tree native to New Zealand. It is part of the Asparagus family and can be identified by its woody trunks and broad green-gray leaves spreading out over it. It can get quite tall and stands at a maximum of 26.2 feet (8 m). As a houseplant, it thrives best in long-lasting, direct light and needs regular watering. Soil also needs to be well-draining, and your Cabbage Tree won't need additional fertilizers if it is repotted every time it doubles in size. It is considered an exotic and exciting plant, and will give your home an ocean resort vibe!

How to care for Blue Dracaena

Difficulty

Caring for Blue Dracaena is a breeze, as it is highly adaptable and forgiving to minor neglect.

Water

Blue Dracaena should be watered regularly, allowing the soil to dry out between waterings.

Soil

Blue Dracaena loves a well-draining soil. Perlite and vermiculite help with drainage, while coco coir adds organic matter, so a good potting soil mix will have all three. You can improve store-bought soil by adding some perlite to it.

Lighting

To ensure optimal growth, the Blue Dracaena prefers bright indirect light for 6-8 hours each day. Insufficient light can result in slow growth and leaf drop, so it's important to find a well-lit location for this plant. Place it near a window, within a distance of 1 meter (3 feet), to enhance its potential for thriving.

Dormancy

During the cold period, it is common for Blue Dracaena to go dormant, resulting in a slowdown of growth. To accommodate this, waterings should be spaced out more.

Toxicity

There is no verified data on the toxicity of this plant in the records of Ploi. If any person, including yourself, a family member, or a pet, consume plant material with an uncertain toxicity level, it is advisable to seek the advice of a healthcare expert.

Humidity

No extra humidity is necessary for the Blue Dracaena. Absorption of water by plants is primarily done through their roots, and soil watering is the most effective method to provide humidity to your plants.

Fertilizer

Repotting the Blue Dracaena should be done either when it has doubled in size or on a yearly basis, whichever occurs sooner. Fresh potting soil with all the required nutrients, refreshed annually, will provide the plant with all the necessary sustenance, making the use of fertilizer unnecessary. Keep in mind that plants receive their energy from the sun, not fertilizer.

Region of origin

Blue Dracaena’s native range is Western Pacific.
