Mountain Cabbage Tree (C. indivisa)
Also known as: Blue Dracaena · Broad-leaved Cabbage Tree · Toi
What's special about Mountain Cabbage Tree (C. indivisa)
New Zealand native with broad blue-green leaves; slower-growing and more cold-tolerant than C. australis.
Growing this variety
Mountain Cabbage Tree (C. indivisa) follows the same growing basics as Cabbage Tree. Variety-specific maturity above; everything else below applies to the whole Cabbage Tree family.
Germination
Spacing & depth
How to plant
Sow fresh seed on the surface of well-drained mix; keep warm and moist. Transplant to a sheltered site with good drainage.
Pre-sow treatment
No cold stratification; sow fresh seed.
Grower's tip
Palm-like evergreen with long strappy leaves on woody trunks; young plants resemble spiky Dracaena.
Soil preferences
Deep, well-drained native soil. Avoid amending the planting hole heavily — roots should learn to grow into the surrounding earth.
5.5–7.5 depending on species (conifers lean acidic; most hardwoods neutral).
Top-dress with compost and mulch in a wide ring; don't backfill with pure compost.
Watering
Deep soak weekly the first two years while roots establish; taper once the tree self-supports.
Slow trickle at the drip line, not the trunk. A 5-gal bucket with a pinhole is ideal.
Overwatered: yellowing, root rot, mushroom collar. Underwatered: leaf scorch, early leaf drop.
Prefers top-watering — Top-water only — deep slow soak at the drip line, never at the trunk. Bottom-watering is only for tree seedlings in nursery pots (shallow tray 15 min). Established trees always get watered from above onto the soil.
Temperature tolerance
Broad — most species tolerate 40–90°F once established
Down to species-rated USDA zone minimum
Hardy once established; young seedlings need protection their first winter.
Special germination requirements
Most temperate tree seed needs cold stratification (30–120+ days at 34–41°F) — see each species entry for the exact time.
Container growing
Possible with the right cultivar
Deep tree pots (root trainers) for the first 1–2 seasons; permanent site required for full growth.
Only dwarf, patio, or bonsai forms live long-term in containers.
Detailed harvesting
Not applicable for ornamental/timber trees. Nut and fruit species — pick when they drop naturally.
Post-harvest storage & preservation
Nuts: keep damp and cool, sow promptly. Winged/coned seed: dry, cool, dark in a sealed jar.
Culinary, medicinal & other uses
Shade, windbreak, wildlife habitat, timber, ornament, and long-term carbon storage.
Medicinal or traditional uses are shared for interest only — this is not medical advice. Consult a qualified professional before using any plant medicinally.
Seed saving
Wind- or insect-pollinated; seedlings rarely match the parent exactly (especially named cultivars — those must be grafted or cutting-grown).
Not practical for trees. Expect variation.
Collect fully ripe seed in fall, clean, dry or keep damp per species, then cold-stratify before spring sowing.

Trees usually mean patience — collect fully ripe seed in fall, clean pulp off, and give most species a cold winter (real or in the fridge) before they'll germinate.
- 1Collect ripe seed/nuts/cones in autumn from a healthy parent.
- 2Clean off any fleshy pulp; dry cones warm to release seed.
- 3Cold-stratify in a bag of damp sand or peat in the fridge (34–41°F) for the time listed on the species.
- 4Sow in deep tree pots and grow on 1–2 seasons before planting to a permanent spot.
Storage: Most tree seed keeps 1–3 years cool and dry; oak/hickory/chestnut nuts must stay damp and be sown promptly.
