Plants of the World Online has a different treatment for this taxon. It gives Larix × eurolepis A.Henry as the correct name for this artificial hybrid, with Larix × henryana Rehder as its synonym, whilst it treats Larix × marschlinsii Coaz as a different, distinct hybrid with parentage Larix decidua × Larix sibirica. See https://powo.science.kew.org/taxon/urn:lsid:ipni.org:names:60477049-2 and https://powo.science.kew.org/taxon/urn:lsid:ipni.org:names:676901-1 (both accessed 14/01/2024)

Cultivation Details

Larix × marschlinsii is a very cold-hardy species; when fully dormant, it can tolerate temperatures down to -30°c or even lower. However, in mild, maritime climates the trees can be excited into premature growth by mild spells during the winter and they are then very subject to damage by late frosts and cold winds[].
Prefers an open airy position in a light or gravelly well-drained soil[]. Plants are intolerant of badly drained soils, but they tolerate acid and infertile soils[]. Succeeds on rocky hill or mountain sides and slopes[]. A north or east aspect is more suitable than west or south[].
This is a very fast growing hybrid, it is often planted as a timber crop[]. Young plants can put on 1.5 metres of growth a year, whilst some trees have reached 16 metres tall within 15 years from seed[].
Hybridizes freely with other members of this genus[].
Open ground plants, 1 year x 1 year are the best for planting out, do not use container grown plants with spiralled roots[]. Plants transplant well, even when coming into growth in the spring[].
Plants in this genus are notably resistant to honey fungus[].
In Scotland, a spontaneous hybrid occurred around 1900 between Larix kaempferi and Larix decidua, which was named Larix ×eurolepis Henry (but is correctly named Larix ×marschlinsii Coaz based on an earlier crossing event) and shows marked F1 hybrid vigour or heterosis. Its seed cones resemble those of Larix kaempferi with recurved scale apices, but are larger. This fast growing hybrid became much favoured by foresters and has been propagated and planted widely in many parts of Europe, often involving back-crosses with either parent[].

Agroforestry Uses:

A fast growing, wind-resistant tree, it can be used in shelterbelts[].. Suitable for planting in open locations, it can be used as a pioneer tree for afforestation.

Other Uses

Resin is extracted by tapping the trunk, it has a wide range of uses including wood preservatives, medicinal etc. The bark is a source of tannin[].

Wood - strong, heavy and durable[].

Propagation

Seed - sow late winter in pots in a cold frame. One months cold stratification helps germination[]. It is best to give the seedlings light shade for the first year[]. As soon as they are large enough to handle, prick out the seedlings into individual pots. Although only a few centimetres tall, they can be planted out into their permanent positions in the summer providing you give them an effective weed-excluding mulch and preferably some winter protection for their first year. Otherwise grow them on in the cold frame for their first winter and plant them out in early summer of the following year. The seed remains viable for 3 years[]. This species is a hybrid so seed will not come true to type.
If you are growing larger quantities of plants, you can sow the seed in an outdoor seedbed in late winter. Grow on the seedlings in the seedbed for a couple of years until they are ready to go into their permanent positions then plant them out during the winter.
