Various species of larch are distributed widely in the circumarctic forests, some extending as far south as the Pacific Northwest and the Atlantic Northeast. The larch is a tree of many uses: house framing, railroad ties, shipbuilding, pilings (as at Venice), telephone poles, turpentine production, and the manufacture of baking powder. In the British Isles Larix decidua is the most planted exotic tree. Larch is also a widely valued and versatile ornamental, and is used for street planting in cold mountainous places. It is deciduous, unlike most conifers. Stanford has little to show of this respectable tree.

Dunkeld larch was discovered at Scotland’s Atholl Estates after a group of Japanese larch (L. kaempferi), imported in 1885 by the 4th duke, were pollinated by the nearby European species (L. decidua) in the estate’s commercial woodlands. A disoriented hybrid (L. ‘Varied Directions’) of Dunkeld larch was in the circular island at the south end of the Braun Music Center archway; it did not survive and was removed in winter 2009. It exhibited the characteristic well-spaced tufts of short needles. When the leaves fell there was a display of charming, upright, 1-inch cones whose scales follow the Fibonacci pattern. If a twig were collected, the dark winter buds could be used to study the larch’s spiral phyllotaxy.

A drooping L. decidua ‘Pendula’ on the east side (in back lawn) of Harmony House off Lomita Drive succumbed as well, and was removed in winter 2009.
