Latin Name:  Larix lyallii
Common Name:  Sub-alpine larch
Family:  Pinaceae
Author:  Parl.

Known Hazards:  None known

Mature Height:  25   Mature Width:

Habitat:  Sub-alpine to alpine zones, often on north-facing slopes where snow lies until late in the season[60].

Cultivation Notes: Prefers an open airy position in a light or gravelly well-drained soil[200]. Intolerant of badly drained soils, but tolerates acid and infertile soils[200]. Succeeds on rocky hill or mountain sides and slopes[200]. A north or east aspect is more suitable than west or south[1]. This species is very cold-hardy when fully dormant, but the trees can be excited into premature growth in Britain by mild spells during the winter and they are then very subject to damage by late frosts and cold winds[1]. Plants are not very successful in Britain, they have been tried on many occasions but have failed to make a satisfactory tree[11, 185]. A specimen at the Hillier Arboretum was 4.5 metres tall in 1970 and suffered frost damage each year[185]. This species is impossible to grow in lowland Britain, though it should succeed above a height of 300 metres in the eastern Scottish Highlands[200]. Growth is normally slow in Britain with average height increases of less than 30cm per year[185]. Hybridizes freely with other members of this genus[200]. Closely related to L. occidentalis[200]. Open ground plants, 1 year x 1 year are the best for planting out, do not use container grown plants with spiraled roots[200]. Plants transplant well, even when coming into growth in the spring[200]. Plants in this genus are notably resistant to honey fungus[200].
