Tamarack
Larix laricina 路 Pinaceae 路 also Eastern larch, American larch, Hackmatack
A deciduous conifer: an open, fine-textured pyramid of soft blue-green needles in tufts that turn brilliant yellow in autumn and drop, leaving a rugged bare silhouette with tiny upright cones. It survives -60 C and grows in bogs and swamps where little else will, which makes it useful for wet yards and restoration, though it is shallow-rooted and dislikes heat, drought and pollution.

Where it stands
Care
Plant in full sun on moist to wet ground and water in dry spells. Little pruning is needed; avoid raising the water table around established trees. Larch sawfly and larch casebearer can defoliate it, and eastern larch beetle attacks weakened trees. New owners should expect the autumn needle drop.
