Pseudolarix amabilis
golden larch
Eastern China (Zhejiang, Jiangxi, Hunan, Hubei, Anhui, and Fujian provinces); montane forests 3,000–5,000 ft (900–1,500 m); rare in the wild and IUCN-vulnerable; monotypic genus
Overview
Pseudolarix amabilis (syn. P. kaempferi) is a deciduous conifer reaching 40–60 feet (12–18 m) tall and 25–40 feet (7.6–12 m) wide, with a broadly conical to pyramidal habit and horizontal to slightly pendulous branches. Soft linear needles 1.5–3 inches (4–8 cm) long are borne in clusters of 15–30 on short spur shoots (a form shared with Larix spp.), are light green in spring and summer, and turn golden yellow to orange-gold in autumn before falling — a vivid autumn color transition not found in most coniferous trees. Cones are barrel-shaped, 2–3 inches (5–8 cm) long, with thick fleshy artichoke-like scales that turn golden brown at maturity and disintegrate on the tree rather than falling intact. Growth rate is slow. Hardy in USDA zones 5–8. Pseudolarix spp. is a monotypic genus — the only species in the genus — and is among the small number of deciduous conifers in cultivation. The species intolerates alkaline soils, compacted urban substrates, and air pollution, and the slow growth rate means a planted specimen takes 15–20 years to reach meaningful size.
Native Range
Pseudolarix amabilis is native to eastern China, in montane forests of Zhejiang, Jiangxi, Hunan, Hubei, Anhui, and Fujian provinces at 3,000–5,000 feet (900–1,500 m). The species is rare in the wild and listed as vulnerable by the IUCN.Suggested Uses
Planted as a specimen in large gardens, parks, arboreta, and estate landscapes at 25–35 foot (7.6–10.7 m) spacing in USDA zones 5–8. The golden yellow to orange-gold autumn color transition is a visual anchor in mixed-conifer and ericaceous plantings, combining with Rhododendron spp., Pieris spp., and understory ferns on acidic sites. Artichoke-like cones and the deciduous-conifer habit support educational and arboretum plantings where the monotypic genus is used to illustrate conifer diversity. Small gardens at the species' 40–60 foot (12–18 m) mature height, alkaline soils, urban compacted substrates, and positions exposed to air pollution or road salt fall outside the species' adapted range.How to Identify

Height40' - 60'
Width/Spread25' - 40'
Reaches mature size in approximately 40 years
Bloom Information
Produces pendant male pollen strobili at shoot tips in April and May. Female cones mature on the tree to 2–3 inches (5–8 cm) long, barrel-shaped, with thick fleshy artichoke-like scales, golden brown at maturity, disintegrating on the tree rather than falling intact. Seasonal feature: golden yellow to orange-gold autumn foliage before needle drop.
