4 Highest species:

Eastern Hemlock (Tsuga canadensis), CC= 8

White lines on back of needles, Feathery silhouette

The eastern hemlock can take 250-300 years to reach maturity (and it can live for more than 1,000 years) (Pennsylvania State Tree | Eastern Hemlock, n.d.)!

Sycamore (Platanus occidentalis), CC= 7

Broad, large, maple-like leaves from a large tree

Sycamores, with their ability to grow to 100 feet, are the largest tree in the eastern USA (Sycamore Tree Care, n.d.).

Blue Ash (Quercus bicolor), CC = 7

Opposite Leaves

Square Stems

According to the University of Kentucky, the Blue Ash “thrives in full sun on rich, moist, well-drained soils” (Blue Ash | Department of Horticulture, n.d.).

Tulip Tree (Liriodendron tulipifera), CC= 6

Four lobes with rounded notches, Missing apex

Named after its flowers resemblance to tulips, these trees are “pH adaptable but performs best in soil that is slightly acidic” (Tulip Poplar | Department of Horticulture, n.d.).

 

4 Lowest species:

California Goldenrod (Solidago canadensis), CC= 1

Lance shaped leaves and masses of yellow flowers 

This plant is everywhere– but pollinators and birds love it (California Goldenrod, Solidago Velutina Ssp. Californica, n.d.)!

American pokeweed (Phytolacca americana), CC= 1

green fruit (later turns purple) on red/purple stems

Although it looks pretty, this herbaceous, weedy plant is toxic (Common Pokeweed Identification and Management, n.d.).

Poison-ivy (Toxicodendron radicans), CC= 1

Leaflets of three, 2 unsymmetrical leaflets with on side serrate, long stem connecting tip leaflet

Contrary to popular belief, the poison-ivy rash is not contagious. You must directly come in contact with the plant itself (5 Fast Facts About Poison Ivy, Poison Oak and Poison Sumac, 2019).

Black-Eyed Susan (Rudbeckia hirta), CC= 1

Bright yellow with dark brown “cone” center disk 

This assertive flower symbolizes justice (Almanac, n.d.).
