A lot of our spring wildflowers are wide awake at Mohonk Preserve! We’ve been avidly keeping track of first bloom dates for many species.

Our native spring ephemerals are past peak by now, including Trout lily (Erythronium americanum) which is now developing fruits down at the Testimonial Gateway, Blunt-lobed hepatica (Anemone americana) can be found along Oakwood Drive and Duck Pond Trail along with Bloodroot (Sanguinaria canadensis). Jack-in-the-pulpit (Arisaema triphyllum) and Red trillium (Trillium erectum) can be also be found throughout the Preserve at this time.

Two species of spring beauty can be found throughout the Preserve and often in the same general area. Virginia spring beauty (Claytonia virginica) has more slender, grass-like leaves, whereas Carolina spring beauty (Claytonia caroliniana) has more ovate leaves.

Red elderberry (Sambucus racemosa) flowers are in bloom. While the black elderberries are edible and used for immune tonics, red elderberries are toxic to humans.

This list is just a sampling of what we have been observing! More and more plants are blooming every day.

One clap, two clap, three clap, forty?

By clapping more or less, you can signal to us which stories really stand out.
