Three Kings Cabbage Tree

From Seed

Cordyline obtecta can be successfully propagated from fresh seed, offering excellent germination rates when proper collection and processing techniques are employed. The species produces clusters of small, blue-black berries that ripen during autumn and early winter, typically from March through June. Fresh seeds have significantly higher viability rates than stored seeds, making immediate processing essential for optimal germination success. Seeds retain viability for only short periods once removed from the fruit, emphasizing the importance of prompt sowing.

Collect ripe berries when they are fully colored and feel soft to the touch, easily separating from the fruiting stalks. Remove the fleshy fruit pulp completely by gently mashing berries in lukewarm water, then floating away the flesh to leave clean, viable seeds. The seeds are relatively large and easy to handle compared to many native species. Rinse thoroughly in fresh water and surface sterilize with diluted fungicide solution to prevent damping-off diseases during the germination process.

Sow immediately in a well-draining seed-raising mix containing equal parts quality potting mix, coarse sand, and perlite for optimal drainage and root development. Maintain consistent soil moisture without waterlogging, keeping temperatures between 18-22°C for optimal germination conditions. Provide bright, indirect light and ensure excellent air circulation to prevent fungal diseases. Germination typically occurs within 6-12 weeks but can occasionally extend to 4-6 months, particularly during cooler periods. Once seedlings develop their characteristic sword-shaped leaves, transplant carefully to individual containers using moisture-retentive but well-draining potting mix suitable for native plants.

From Cuttings

Cordyline obtecta is exceptionally responsive to vegetative propagation from multiple types of cuttings, making it one of the most reliable native plants for cutting propagation. The species readily produces adventitious roots from emergent shoots, mature stem cuttings, and even substantial trunk sections, offering tremendous flexibility for propagators. This versatility makes it particularly valuable for restoration projects and commercial production where consistent results are essential.

Take stem cuttings during summer months when active growth provides optimal hormone levels for root development. Select healthy, disease-free shoots from current season's growth, cutting 15-30cm lengths with sharp, sterile tools. Trunk sections can be much longer (30-60cm or more) and still root successfully, making this method ideal for creating instant mature-sized plants. Allow cut surfaces to dry for 24-48 hours in a shaded location to encourage callus formation and reduce disease risk during the rooting process.

Plant cuttings vertically in well-draining cutting mix, ensuring proper orientation with the original top of the cutting facing upward. Use a mixture of equal parts coarse sand, perlite, and quality potting mix for optimal drainage while maintaining adequate nutrition. Insert cuttings approximately one-third of their length into the growing medium, ensuring good contact between cutting and soil. Maintain consistent moisture levels without waterlogging, and provide bright, filtered light in a warm, protected position. Root development typically begins within 4-8 weeks, with new shoot growth appearing shortly afterward. Bottom heat can significantly accelerate rooting, particularly valuable during cooler months or for challenging trunk cuttings.
