For my bad plant I choose poison oak. It is in the phylum Anthophyta and its scientific name is Toxicodendron diversilobum. Urushiol oil is what causes the rash produced by poison oak. Only 1 nanogram is needed to cause a rash. Just ¼ of an ounce is needed to give every person on the earth a rash. Urushiol can stay alive for 1-5 years on any surface including a dead plant. It is the most common allergy country and effects half the population. Rubbing the rash won’t spread it if you don’t have the urushiol oil on your hands. Poison oak has three leaves, same as poison ivy.

CASTOR PLANT Ricinus CommunisRicnius Castor oil makes up about 50% of the weight of the seeds. Star-shapedleaves can reach 3 feet in length. It Relies on the wind for pollination. it Containvaluable oil. Egyptian tombs indicate that the oil was used in medicine over6,000 years ago. Intact seeds may pass through the digestive tract withoutreleasing ricin. Symptoms of ricin poisoning begin within hours after exposureby ingestion or inhalation. There is no antidote for ricin poisoning. Castor plants are indigenousto the Mediterranean basin, eastern Africa and India. Humans are the most sensitive to theseseeds. It takes 1-4 to kill afull grown human, 11 to kill a dog and 80 seeds to kill a duck. It currently holds theGuinness World Record for most poisonous plant. The cause of death will be dehydration.One raw seed is enoughto kill a human in 2 days. A toxin called ricin is found throughout the plant,Itcauses an agonizing and unstoppable deathVrey, Christine.

Gelidocalamus fangianus
Anthophyta
Bamboo grew on every continent exceptAntarctica and Europe. It is mostly found in Asia though. There are a lot ofinteresting things about bamboo. It was the first plant to re-green after theatomic blast in Hiroshima in 1945.The bamboo foliage can be up to 22% protein.
A grove of bamboo release 35% more oxygen than an equivalent stand of trees.
Ethanol and liquid diesel can be produced using bamboo as the raw material.
Becauseof the strength to weight ratio of bamboo it was used for some of the first
airplane designs. When wet bamboo cables increase in strength by as much as 20%.
Thedevelopment of gunpowder in China included the skin of bamboo. The most common
place for bamboo to grow is in Southeast Asia. Between 1,200 and 1,500 species
of bamboo have been found. Technically a “weed”,. Bamboo can grow up to 4 feet per day. Bamboo has a tensile strength greater than the same size piece of steel.
Bamboo has a very high rate of photosynthesis.

The Northern Red Oak is from the family Fagacea. It is under the phylum name anthophyta. Its scientific name is Quercus rubra its commonly called a northern red oak. It is found in east
Canada and the Midwest US. The Northernred oak can grow potentially from 60-90 feet. The northern red oak is a large hardwood tree that has dark green leaves that turn to rusty orange and various shades of red in the fall. They reproduce from both seeds and root sprouts. They produce acorns. Redoak has light-colored, hard, close-grained wood that is used for a variety of
purposes from fence posts and flooring to furniture. Also used in medicinal uses for digestive
disorders, respiratory diseases, and skin infections. Generally, northern red oak is found on relatively moist sites with deep, rich soils. The tree has a single, lobed leaf with seven to eleven pointed or bristly-tipped lobes. These trees have been known to live 300-500 years. Acorns provide a food source for numerous birds and animals. The twig is red-brown in color, with large, multiple, terminal buds that are covered with scales. The bark develops flat ridges with shallow furrows. The bark is dark gray and sometimes a black color with the furrows being a reddish color. Red oak acorns are larger than any other acorn. This tree is the most widely used oak tree in the world!

Poison sumac is in the phylum anthrophyta. Its scientific name is Toxicodendron vernix, commonly called poison sumac. It is often found in very wet areas of the eastern United States. It is a tree looking plant that can grow to be 30 feet tall. All parts of the plant contain a resin called urushiol that causes skin and mucous membrane irritation to humans. When burned, inhalation of the smoke may cause the rash to appear on the lining of the lungs, causing extreme pain and possibly fatal respiratory difficulty. Poison Sumac is not very common. Really woody and it actually grows into a tree instead of a small plant or shrub like poison ivy and poison oak. The leaves of the plant are smooth. There are no hairs on the stems. 7-9 leaves per stem. This plant is very bad. It only takes 1 nanogram of oil from this plant to cause a rash, and the average human get 100 nanograms of oil every time they come in contact with the plant. All parts of the plant are poisonous, including the bark. Some people are not affected by the plant. According to some people, poison sumac is the most dangerous plant in the United States.

resemble grapes. It is native to eastern North America where it is found in
woods and hedges, but fortunately not commonly. The key to recognizing moonseed
drupes is that they have only one large crescent-shaped seed, while grapes have
many seeds. Birds eat the drupes with no apparent harm, which only shows that it
isn’t always safe to eat what birds eat. These drupes are poisonous, producing
severe abdominal pain and indigestion."Poisonous Plants — Moonseed.Moonseed, a deciduous climbing vine, is fairly common throughout North
Carolina in floodplain forests and other moist wooded areas.Drooping panicles of tiny white flowers appear in mid- to late-spring. The leaves and all other parts of the plant are toxic.

The good plant that I chose would be the redwood. The redwood tree belongs to the phylum coniferophyta. The scientific name for this tree is sequoia sempervirens. This tree is mostly
found off of California’s coasts. This tree is the world’s tallest and largest
living tree known to man. This tree can weigh in at up to 500 tons. It also has
an average life span of 500 to 700 years old. The reason these trees live for
so long is because the tree sap is mostly water based. The reason for it being
water based is because the tree holds up to 34000 pounds of water. Another
reason why this tree has such a long life span is because the tree cannot be
killed by a bug. This tree is truly amazing some interesting facts that
surprised me are that the bark grows between 10-20 inches thick also the roots
only grow 10-13 feet deep but once that deep they spread out and intertwine
with the other neighboring. Some of the uses for this tree are lumber, railroad
ties, and also used to make expensive furniture.
found all over the world but mostly found in the US, Europe and Asia. The
dandelion is originated from Europe and Asia. This plant is known as a
perennial. The dandelion grows between 3-12inches long and has thick highly
branched taproots. The dandelion is traced back 30 million years and found
round the world. Even though the dandelion is known for many cures of sickness
and is a food source, it gets a bad name because of how it takes over yards.
The dandelion takes over yards so quickly because the way it spreads. The
dandelion spreads by it seeds that float through the air and land on the ground
and if the seed is in a favorable place it sprouts on the soil. The only way to
stop this plant from growing is by pulling it out of the ground or by using a
herbicide. Another disadvantage of this plant is that it attracts bees. The
dandelion is a bad plant because of outrageous reproducing habits

This plant is native to East Asia, South China and Japan. They live in mostly woodland garden, sunny edges, and in dappled shade. The soil type has to be clay, loam, or silt. The acidity of the soil has to between 5.5 and 6.5 on the pH scale in order for the plant to live. They produce seeds to reproduce. They go through a delayed hypogeal germination. During pollination, bees are the common pollinators of this plant. The honey scent of this flower helps attract them. There are less than 100 known species of lily. The lily also is symbolic; it symbolizes purity of heart, majesty and honor.
In mostly China and Japan, there are trees called bonsai trees. These trees are called “bonsai” cause of the method of growing them. Bonsai comes from two Chinese characters meaning “tree” and “planted in a shallow container.” This is a form of art in horticulture. There are five different shapes of bonsai trees. Formal is a single up growth with an upright trunk that tapers at the top. Informal is similar the formal, but has a cured or leaning trunk. Semi or full cascade has an arching or cascading trunk. Group or forest method is where multiple trees symbolize a small landscape. The last form is free form, which has a sparse single growth.
These trees have many propagation methods of growth. They can grow from seeds, grafting, cutting, and layering. There is not one species of bonsai. Each bonsai plant is just a smaller, human affected tree. The Japanese maple bonsai is from the phylum Anthophyta and is Acer palmatum (the scientific name). This is the same as the original Japanese maple tree. This plant is used in spiritual healing. They help clam, to relax, and sooth people.

Wild Quinine is in the phylum Asteracea. Its scientific name Parthenium integrifium. The common name is wild quinine. The location of wild quinine is very widespread, but a lot are found in the state of Illinois. Wild quinine is a good plant. Wild Quinine is a very valuable medicinal herb. It is used as an antiperiodic, emmenagogue, kidney, lithontripic, poultice. It has traditionally
been used in alternative medicine to treat debility, fatigue, respiratory
infection, gastrointestinal infection, and venereal disease.
The preference for wild quinine is full sun and mesic conditions. However, a small amount of
shade is tolerated, and the soil can vary from moist to slightly dry. A fertile
loamy soil is preferred, although the presence of some sand or rocky material is
tolerated. While established plants are fairly easy to grow, recent transplants
can be temperamental. It is important to put the transplants into the ground
after danger of hard frost has passed, but before the period of active growth
occurs during the late spring and early summer. Foliar disease isn't a
significant problem. During a drought, some of the lower leaves may turn yellow
and wither away.The flowers attract Halictine bees, wasps, flies, beetles, and plant bugs. The
beetles usually feed on pollen, while the other insects seek nectar primarily.
The fly visitors include Syrphid flies, Tachinid flies, Flesh flies, Muscid
flies, Anthomyiid flies, and others. Wasp visitors include Crabronine wasps,
Eumenine wasps, Cuckoo wasps, Braconid wasps, and others. Mammalian herbivores
appear to ignore this plant as a food source because the leaves are sandpapery
in texture and bitter-tasting.
Daphne
The phylum name of Daphne is Thymelaeaceae. The scientific name is Daphne mezeureum. Its common name is Daphne or Daphne Laurel. Daphne is a bad plant. The berries and leaves produced by the plant have a toxin in them. The daphne plant originated in Europe, and it is a landscape plant. The plant is poisonous if and by ingestion, Poisonous parts are the fruits and leaves. Symptoms if ingested can be swelled lips, thirst, and internal bleeding. Contains diterpenoid that can cause skin irritation. The daphne plant is also called spurge laurel and also called paradise plant. One berry swallowed of Daphne can cause severe
throat irritation. Daphne is grown as an ornamental plant. Some places it is found are in Ohio, Montana, and Alaska in the U.S.A. It is also found a lot in Ontario, Canada.
The berries are five centimeters in diameter. The habitat of Daphne is a shrub. It is a perennial which means it stays through out the year, and a shrub can grow up to five feet.

GOOD
A plant that greatly helps human kind in general is the Castor plant or Ricnus
communis. This plant belongs to the phylum’s Angiosperm and Magnoliophyta, it
is found in the tropics of East Africa. The Castor plant likes hot dry soil, so
it thrives in the tropics of Africa. It is a medium height, fruit bearing plant
with eight points on its leaves. The Castor plant reproduces through pollination.
Unlike some, it has a male and female flower on the same plant and can
reproduce on its own. The seeds or Castor beans, produced through reproduction,
are enclosed in a light-green, spiked case or shell. When the shell dries out
it, splits into three parts and the bean then falls out.
The plant also produces Castor oil on the leaves. This oil is very useful to
humans; we use it in art supplies, clothing material, and even for vehicles.
The first use of the oil was in oil paints. The pigments were mixed with Castor
oil and it creates a waxy or shiny color. Second, we use Castor oil in the
production of nylon. The Sebacic acid is one of the most basic ingredients in
the nylons production. Third, the Ricin in small enough quantities is known to
kill viruses that cause gastrointestinal problems. Fourth, and probably the
most important use, is in motor oil. This oil is a great lubricant even at very
high temperatures. It is also where they got the name "Castrol" motor
oil.
Ten percent of the feed for hogs, sheep, and horses is made of the Castor bean. The
bean is boiled at a temperature of 140 degrees for twenty minutes to inactivate
the toxic protein Ricin.
There is however some very poisonous parts of this plant as well. The oil can be
toxic if ingested, along with the beans. The toxic protein, Ricin, is the cause
of this. It is found traveling through the plant in the phloem. Scientists
found this out in January of 1970, when almost 10,000 Mallard ducks were found
dead due to the ingestion of the Castor beans. There was also a massive
decrease in insect population due to the oil on the leaves of the Castor plant.
It is also toxic to humans, in 1978 Bulgarian journalist, Georgi Markov, was
assassinated for speaking out against the Bulgarian Government. He was stabbed
in the leg by the hollowed out point of an umbrella, which had a pellet filled
with the Ricin toxin from the Castor plant.
production of oil; and two a shatter proof shell. The higher oil production is
very useful for the increasing dependence on vehicles. While the shatter proof
shell allows the bean to continue growing even after it falls from the plant,
and also provides protection during the harvest of the fruit.
BAD
The African Milk plant, Euphorbia lactea in the phylum Magnoliophyta, is a highly toxic plant
found in the tropical parts of Asia, the West Indies, and Florida. The African
Milk plant grows well in dry and porous soil, much like the loam and sand of
the desert wastelands. It is nick-named the Candelabra plant, due to the
structure of the "branches" or "arms". Some other names for
it are Dragon Bones (tree), Caper Spurge, and Candle-stick tree. Due to
hybreading, there is also a Ghost form of this plant, which would burn and wilt
if it was in the direct sunlight of the tropics. This plant is very tall,
resembleing a cactus, a dark-green in color, with many branches. The cactus has
three sides and a white milky liquid inside. All of this plant is poisonous.
The "milk" flows through the entire plant distributing nutrients
throughout, this is where the toxin, Diterpene, comes from. It may cause
nausea, vomiting, or diarrhea if ingested; and redness, swelling, or blisters
if it contacts the skin. It can also cause blindness if it gets in the eyes.
The best way to reproduce this plant is through grafting. This is what causes all the hybrids;
it also explains why the cactus has such a slow growth rate. There are too many
hybrids to definitely know which one you have, just by looking. The three most
common hybrids are the; E. lactea "ghost", that have nearly white
stems. The E. lactea "giant" with a much larger stem, E. lactea
"crest", which comes with many different colored forms, and the
original E. lactea that stands around four and a half meters tall and is a dark
green color.
Even with all the
toxins running through it, it does still have some uses to help human life. The
African Milk plant fights of warts and tumors if placed directly on the source.

Iris- Good Plant
The plant Iris belongs to the phylum Anthophyta. The scientific name is Iris Pseudacorus, and it's commonly called the "Bearded Hybrids." There is about 300 species of Iris and its very useful in many different ways. It can be used for treating dandruff, and even wounds. It can also be used in some affection such as asthma, bronchitis, and the common cough. Some people have even used Iris for acne. You compress a flower two or three times a day for about fifteen minutes. Iris is even used in some perfumes and cosmetics too. Fragments of rhizomes in this plant are sometimes given to babies to help with the teething process. This flower can grow anywhere from 3 to 4 feet, and usually bloom anytime between April and May. They come in several different shapes, sizes, and colors. The possible colors are blue, purple, white, yellow, pink, orange, brown, red, and even black. Iris has two major groups, Rhizome Irises, and Bulbous Irises. Rhizome Irises are thickened stems that grow horizontally, and underground. Bulbous Irises grom from bulbs that need a stage of dormancy after they have bloomed. One last interesting fact about Iris is that this plant was named after a greek goddess, which travels on a rainbow. Iris was named after this goddess because of the variety of colors that this flower comes in.Z. Carter

Lavandula officinalis is located in mountainous zones of the Mediterranean and flourishes throughout southern Europe, Australia, and the United States. Its common name is lavender and is from the phylum Angiosperm. This plant is good and has been used for over 2,500 years. It is often used for massages, acupuncture, and chiropratic manipulation. Scientific evidence has shown that armotherapy with lavender may slow the activity of the nervous system, improve sleeping quality, promote relaxation, and lift the mood in people suffering from people with sleeping disorders. Lavender may be used in diluted concentrations to treat skin infections and injuries such as cuts and scrapes and prevent midge and mosquito bites. It is used also to moisturize skin and is used in healing baths for healing joint and muscle pains. It is considered the premier of all perfume. In tudor times, lavender brew was sipped by maidens on St. Lukes day to divine the identity of their true loves. Lavender grows as a compact bush up to 30 inches and can treat microbial activity on gums. Egyptians also used lavender for mummification. Charles VI of France demanded lavender filled pillows wherever he went to relax and help with sleep.
