Smooth Sumac
Tamarack Larch

Smooth Sumac is an excellent shrub for both its ornamental appeal and tolerance of difficult planting sites. You'll love the attractive pyramidal spikes of hairy, red berries that emerge on female plants and the fern-like foliage that covers both male and female varieties.

Ensure you give Smooth Sumac enough space to spread out due to its high suckering nature. While not ideal for small, urban yards, this shrub will make a stunning border along a woodland edge or roadside.

Note:These plants typically reach maturity and make their sex easily known (females producing fruit) in their 3rd or 4th year of growth. Our seedlings are too young to identify their sex.

Staff Favorite!

Tamarack is a small to medium-sized native conifer tree featuring needles that turn an attractive gold before dropping in the fall.

This cold-tolerant tree grows well in very wet conditions, as long as it is exposed to full sun.
