Pseudolarix amabilis is a

Growth

It is a

coniferous tree reaching 30–40 m (98–131 ft) tall, with a broad conic crown. The shoots are dimorphic, with long shoots and short shoots similar to a larch, though the short shoots are not so markedly short, lengthening about 5 mm annually. The leaves are bright green, 3–6 cm long and 2–3 mm broad, with two glaucous stomatal
bands on the underside; they turn a brilliant golden yellow before falling in the autumn, hence the common name "golden larch". The leaves are arranged spirally, widely spaced on long shoots, and in a dense whorl on the short shoots.

The

globe artichokes
, 4–7 cm long and 4–6 cm broad, with pointed triangular scales; they mature about 7 months after pollination, when (like fir and cedar cones) they disintegrate to release the winged seeds. The male cones, as in Keteleeria, are produced in umbels of several together in one bud.

Characteristics

The golden larch is an attractive ornamental tree for parks and large garden. Unlike the true larches, it is tolerant of summer heat and humidity, growing successfully in the southeastern United States where most larches and firs do not succeed. In Europe growth is most successful in the Mediterranean region with notable specimens in northern Italy; further north in the United Kingdom it will grow, but only very slowly due to the cooler summers.

This plant has gained the Royal Horticultural Society's Award of Garden Merit.[3][4]
