When does Larix laricina bloom?

Tamarack produces small reddish male and female cone clusters in April and May before the new needles fully emerge. It is wind pollinated rather than insect pollinated.

How much water does tamarack need?

Tamarack does best in consistently wet to moist soil and is often found growing in bogs, swamps, and along pond edges. It tolerates standing water better than most conifers but can also grow in moderately moist upland sites.

Does tamarack keep its needles year round?

No. Unlike most conifers, tamarack drops its needles every autumn after they turn golden yellow, making it a deciduous conifer.

How much sun does Larix laricina require?

Tamarack is shade intolerant and grows best in full sun. Trees in shaded conditions tend to thin out and lose vigor over time.

Is Alaskan Larch toxic to livestock?

The USDA PLANTS Database does not flag Alaskan Larch as toxic to livestock.

Is Alaskan Larch HOA-friendly?

Alaskan Larch takes more care to look intentional in a front yard. Consider it for backyard or mid-zone beds rather than the street edge.
