Wetland conifer of the eastern U.S. with soft, scale-like blue-green foliage.
Chinese Weeping Cypress
N/Aalso: Chamaecyparis funebris, Mourning Cypress
Weeping evergreen with pendulous branches; warm-temperate species.
Hinoki Cypress
N/Aalso: Chamaecyparis obtusa, Hinoki False Cypress, Japanese White Cedar

When & where
Germination
Spacing & depth
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
60–90 days cold stratification.
Grower's tip
Conifer genus valued for dense, scale-like foliage in green, blue, gold, and variegated forms.
Woody plant facts
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 — Trees are always top-watered — deep slow soak at the drip line, never at the trunk. Bottom-watering only makes sense for nursery seedlings.
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.
