Female flowers produce showy pyramidal fruiting clusters (up to 8″ long), each containing numerous hairy, berry-like drupes that ripen bright red in autumn and gradually turn dark red as they persist through much of the winter.

Male flowers are small, greenish-white or yellow in colour, and form dense terminal panicles.

Male flowers bloom from May to June, while female flowers bloom from June to September.

Habitat

Staghorn Sumac natural habitats are sandy and rocky sites and abandoned fields. They are easily grown in full sun to part shade in average, dry to medium moisture, well-drained soils. Staghorn Sumac are adaptable to many soil types, but they must be well drained. They are generally adaptable to urban environments. In the wild, this suckering shrub will form thickets through self-seeding and root suckering; for this reason, it is not recommended in small gardens as it suckers and spreads quickly..
