Japanese Quince
Cow Parsnip

Japanese Quince has bright, orange to red showy flowers that bloom in early spring. The flowers appear before the leaves and may continue to bloom after leaves emerge. Flowers grow on old wood, so pruning after flowering will help to promote new growth next spring. They produce yellow-green fruit that taste bitter when eaten raw, typically they are better suited for making preserves.

It can be used as a stand alone ornamental shrub, as a low hedge, or can be trained to grow against a wall. In late winter, branches of Japanese Quince can be cut and brought indoors where they will bloom on their own. They are deer and rabbit tolerant. The branches are spiny making them well suited for keeping unwanted wildlife away.

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.
