larix laricina

Answer 2

European Larch (Larix decidua) is a species of larch native to the mountains of central Europe, in the Alps and Carpathians, with a disjunct lowland population in northern Poland.

It is a medium-size to large deciduous coniferous tree reaching 25-45 m tall, with a trunk up to 1 m diameter (exceptionally, to 55 m tall and 2 m diameter).

The crown is conic when young, becoming broad with age; the main branches are level to upswept, with the side branches often pendulous. The shoots are dimorphic, with growth divided into long shoots (typically 10-50 cm long) and bearing several buds, and short shoots only 1-2 mm long with only a single bud.

The leaves are needle-like, light green, 2-4 cm long which turn bright yellow before they fall in the autumn, leaving the pale yellow-buff shoots bare until the next spring.

Pines are evergreen and resinous.

The bark of most pines is thick and scaly, but some species have thin, flaking bark. The branches are produced in regular "pseudowhorls", actually a very tight spiral but appearing like a ring of branches arising from the same point. Many pines are uninodal, producing just one such whorl of branches each year, from buds at the tip of the year's new shoot, but others are multinodal, producing two or more whorls of branches per year.

So the plant you are searching is NOT pine as all are evergreen and do not shed their leaves.

The word you're looking for is 'deciduous'.
