Luckynut

Tree
Sow stratified seed in early spring; collect fresh seed in fall
Full sun to part shade

Also known as: Thevetia peruviana · Yellow Oleander

Danger

Deadly poisonous

Every part of this plant is deadly poisonous. Even small amounts can kill a person, a child or a pet, and the sap can be absorbed through broken skin. Wear gloves, never plant it where children or animals roam, and never put any part of it near food.

When & where

Season
Sow stratified seed in early spring; collect fresh seed in fall
USDA zones
Check the species' native range against your USDA zone before planting.
Sun
Full sun to part shade
Start indoors
After stratification, start in deep pots 8–12 weeks before transplant
Direct sow outdoors
Fall sowing works for many species (natural cold stratification over winter)
Days to harvest
Years, not days — most seed-grown trees take 5–15 years to reach a useful size.

Germination

Germination time
20–60 days after stratification
Soil temperature
65–75°F (18–24°C) after cold treatment

Spacing & depth

Sow depth
Sow large nuts and acorns 1–2 in (2.5–5 cm) deep; winged or small tree seed 1/4–1/2 in (6–12 mm).
Seed spacing
One seed per deep tree pot or root trainer, or 4–6 in (10–15 cm) apart in a nursery bed.
Mature plant spacing
Space to the mature spread — 30–50 ft (9–15 m) — set the planting distance to the mature canopy, not the sapling
Row spacing
N/A — plant single specimens, or 15–20 ft (4.5–6 m) apart in a windbreak row.

How to plant

Stratify seed as noted. Sow in deep tree pots (tall root trainers) filled with well-drained mix. Keep evenly moist and in bright light after germination. Grow on for 1–2 seasons before planting out to a permanent, well-prepared site with a wide mulch ring.

Pre-sow treatment

Cold stratification

Soak seed 24 hours; sow warm.

Grower's tip

Luckynut (Thevetia peruviana) — tropical shrub with bright yellow trumpet flowers; all parts poisonous.

Woody plant facts

USDA zones
Check the species' native range against your USDA zone before planting.
Mature height
40–70 ft (12–21 m) for most shade trees
Mature spread
30–50 ft (9–15 m) — set the planting distance to the mature canopy, not the sapling
Pollination
Wind-pollinated. A single tree sets seed once mature, but a second tree nearby improves seed fill.
Planting depth for seed
Sow large nuts and acorns 1–2 in (2.5–5 cm) deep; winged or small tree seed 1/4–1/2 in (6–12 mm).
Soil pH
6.0–7.0
Disease & problem notes
Keep mulch off the trunk, water deeply rather than often, and prune in dormancy to limit canker and rot entry points.

Good to know before you grow this

Parts of this plant are toxic to people and pets — don't eat it and keep it away from children and animals.

Soil preferences

Soil type

Deep, well-drained native soil. Avoid amending the planting hole heavily — roots should learn to grow into the surrounding earth.

pH range

5.5–7.5 depending on species (conifers lean acidic; most hardwoods neutral).

Amendments

Top-dress with compost and mulch in a wide ring; don't backfill with pure compost.

Watering

Frequency

Deep soak weekly the first two years while roots establish; taper once the tree self-supports.

Method

Slow trickle at the drip line, not the trunk. A 5-gal bucket with a pinhole is ideal.

Over vs. under

Overwatered: yellowing, root rot, mushroom collar. Underwatered: leaf scorch, early leaf drop.

Top-water or bottom-water?

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

Ideal daytime air temp

Broad — most species tolerate 40–90°F once established

Ideal nighttime air temp

Down to species-rated USDA zone minimum

Frost sensitivity

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

Container-suitable?

Possible with the right cultivar

Recommended pot size

Deep tree pots (root trainers) for the first 1–2 seasons; permanent site required for full growth.

Notes

Only dwarf, patio, or bonsai forms live long-term in containers.

Detailed harvesting

Nothing here is harvested for the kitchen. Wear gloves for any cutting or deadheading, keep the sap off your skin and eyes, and wash your hands and tools afterwards.

Post-harvest storage & preservation

Do not dry, store or preserve any part of this plant near food. Bag prunings for the bin — never compost them where animals browse, and never burn them.

Culinary, medicinal & other uses

Ornamental only — this plant is poisonous and has no food, tea or home-remedy use. Grow it for looks, wear gloves, and keep it away from children, pets and livestock.

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

Pollination

Wind- or insect-pollinated; seedlings rarely match the parent exactly (especially named cultivars — those must be grafted or cutting-grown).

Isolation needs

Not practical for trees. Expect variation.

How to save

Collect fully ripe seed in fall, clean, dry or keep damp per species, then cold-stratify before spring sowing.
