On a Conifer Recognition Workshop, so I am 100% sure of the ID!

Here are cones of the three Larches (deciduous conifers, short needles in bunches of more than 10) commonly found in the UK.

First photo:

Left: Larix decidua, European Larch. Cone is oval, chunky, and the scales are held tight against the centre.

Right: Larix kaumpferi, Japanese Larch: the cones are round, with the scales fully reflexed, ie with the tips curving outwards.

Centre: Larix x marschlinsii - Dunkeld or Hybrid Larch, which is a cross between the two. As you can see, the cone is partway between the two: it has the size and oval shape of one parent, and a strong hint of the reflexed scales of the other.

Second photo: as you can see, the cones of Japanese Larch, Larix kaumpferi, are half the size of those of European Larch, and with their reflexed scales, they look like little roses.

Apparently the hybrid is the most commonly planted, as it is more vigourous than either parent.
