Rubus pensilvanicus
Rubus pensilvanicus (R. pensilvanicus), commonly known as the Pennsylvania blackberry, thrives in the eastern and central regions of North America, stretching from Newfoundland south to Georgia and reaching westward to Ontario, Minnesota, Nebraska, and Arkansas.

Rubus genus's genetic complexity and morphological variabilities poses challenges in precisely categorizing its various species. Some authors group what is collectively recognized as R. pensilvanicus, while others discern as many as 50 or 60 distinct species within the intricate genus of Rubus.

Introduction:
Rubus pensilvanicus, also known as the Pennsylvania blackberry finds its home in states like Pennsylvania and New York, as well as, a few patches in the Midwest. This perennial, is a member of the Rubus genus with raspberries and blackberries, stands tall with its thorny canes that deter thin skinned humans and animals from trampling through it. The name "pensilvanicus" alludes to a strong presence in the Keystone State, Pennsylvania, where it has been botanically famous for ages and it named after.

In the summertime, this plant develops into a shrub full with white blossoms, later giving way to the blackberries that have earned it culinary and ecological significance.

Description:
The R. pensilvanicus is a 8 foot tall perennial bramble sporting sharp prickles along its stems. The fruit is black to purple in color, fleshy in texture, and edible to humans and wildlife.

The leaf structure of Rubus pensilvanicus is characterized by compound leaves, composed of two or more discrete leaflets. Along the stem, there is a single leaf per node. The leaf blade edges are serrated, featuring distinct teeth. In terms of leaf duration, the leaves either drop off during winter or wither but persist on the plant. Notably, the plant is armed with spines, prickles, or thorns. The dimensions of the leaf blade range from 110 to 220 mm in both length and width. Each leaf possesses a leaf stalk. The fruit, it is of a fleshy nature. The bark of the mature plant is thin and smooth, while the twigs exhibit a winter coloration in shades of brown or gray. The winter buds are characterized by three or more scales, overlapping like shingles, with one edge covered and the other exposed.

This particular species is hermaphroditic, possessing both male and female reproductive organs, with pollination primarily facilitated by insects.

Taxonomy:
Rubus pensilvanicus is also known as Rubus abactus a synonym. In 1804 R. pensilvanicus was described by Jean Louis Marie Poiret in Encyclopedie Methodique: Botanique. Some common names include: Blackberry, Dewberry, Pennsylvania Blackberry.

Distribution and habitat:
Rubus pensilvanicus can be found in the eastern and central regions of North America, stretching from Newfoundland south to Georgia and reaching westward to Ontario, Minnesota, Nebraska, and Arkansas.

The preferred environmental conditions for Rubus pensilvanicus encompass a range of light exposures, thriving in full sun conditions with a requirement of 6 or more hours of direct sunlight per day. Alternatively, it can adapt to partial shade, where direct sunlight is available only part of the day, totaling 2-6 hours. Regarding soil texture, this species demonstrates versatility, showing affinity for clay, high organic matter, loam (silt), and shallow rocky substrates. Its adaptability extends to varying soil pH levels, with a preference for acidic conditions (<6.0), tolerance for alkaline environments (>8.0), and an ability to flourish in neutral pH ranges (6.0-8.0). Moreover, the plant exhibits adaptability to different soil drainage patterns, thriving in settings with good drainage, as well as in moist conditions and occasionally dry soils. This flexibility in light, soil texture, pH, and drainage underscores the resilience and adaptability of Rubus pensilvanicus across diverse environmental settings.

Conservation
Rubus pensilvanicus is apparently secure in Nova Scotia. While other parts of Canada like New Brunswick and Québec it is listed as S3 venerable.

Disturbance
Rubus pensilvanicus is an early successional plant that is often found in clear-cuts. Frequent disturbance is necessary for Rubus pensilvanicus to grow and thrive.

Considered facultative (FAC), this plant species is equally likely to thrive in both wetland and non-wetland environments, with an estimated probability ranging from 34% to 66%.

Disease
Phragmidium violaceum is a rust fungus that can infect Rubus pensilvanicus.This fungus is from France and was first reported to infect Rubus pensilvanicus in 2005.

Uses
These blackberries can be turned into dyes for writing or dyeing cloths, which is not a new practice. Blackberries are also a source of nutrients and were eaten and dried by Native Americans. Fruits can be made into jams and jellies.

The leaves serve as a browsing source for white-tailed deer with the only sources of defense being the plants prickles. However, the plant is resilient to brows from deer and other various mammals. This bramble is year-round exceptional cover for wildlife. The fruits become a favored treat for songbirds, small mammals, foxes, raccoons, and even black bears. As winter arrives, birds and small mammals eat the seeds left behind from decomposed fruit. The flower blooms attract butterflies and various other insects, creating a diverse environment of pollinators
