Smooth Sumac vs Cow Parsnip

Cow Parsnip is a native perennial wildflower known for its tall growth, very large leaves, and broad clusters of white flowers. The abundant blossoms provide nectar and pollen for a wide variety of pollinators, including bees and butterflies. Birds and small mammals feed on its seeds, while the foliage serves as a larval host for certain butterfly species.

Cow Parsnip is often among the first native perennials to establish in disturbed or open sites. It typically grows in moist meadows, along streambanks, forest edges, and roadsides. Although usually a short-lived perennial or biennial, it readily self-seeds and maintains strong populations where conditions are favorable.

Cow Parsnip is the only native Heracleum in North America and should not be confused with the highly invasive Giant Hogweed (H. mantegazzianum).

Note: The sap of the Cow Parsnip can cause phytodermatitis when exposed to ultraviolet light (sunlight). This can cause rashes or even burns. Care should be taken if pruning or handling this plant.

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.
