Shade-intolerant
In ecology, shade tolerance is a plant's ability to tolerate low light levels. The term is also used in horticulture and landscaping, although in this context its use is sometimes imprecise, especially in labeling of plants for sale in commercial nurseries. Shade tolerance is a complex, multi-faceted property of plants. Different plant species exhibit different adaptations to shade, and a particular plant can exhibit varying degrees of shade tolerance, or even of requirement for light, depending on its history or stage of development. Basic concepts Except for some parasitic plants, all land plants need sunlight to survive. However, in general, more sunlight does not always make it easier for plants to survive. In direct sunlight, plants face desiccation and exposure to UV rays, and must expend energy producing pigments to block UV light, and waxy coatings to prevent water loss. Plants adapted to shade have the ability to use far-red light (about 730 nm) more effectively ...

Tsuga Canadensis2
''Tsuga'' (, from Japanese language, Japanese (), the name of ''Tsuga sieboldii'') is a genus of conifers in the subfamily Abietoideae of Pinaceae, the pine family. The English-language common name "hemlock" arose from a perceived similarity in the smell of its crushed foliage to that of the unrelated plant Conium maculatum, hemlock. Unlike the latter, ''Tsuga'' species are not poisonous. The genus comprises eight to ten species (depending on the Taxonomic authority, authority), with four species occurring in North America and four to six in eastern Asia. Description They are medium-sized to large evergreen trees, ranging from tall, with a conical to irregular crown, the latter occurring especially in some of the Asian species. The leading shoots generally droop. The Bark (botany), bark is scaly and commonly deeply furrowed, with the colour ranging from grey to brown. The branches stem horizontally from the trunk and are usually arranged in flattened sprays that bend downward ...

Enzyme
An enzyme () is a protein that acts as a biological catalyst by accelerating chemical reactions. The molecules upon which enzymes may act are called substrate (chemistry), substrates, and the enzyme converts the substrates into different molecules known as product (chemistry), products. Almost all metabolism, metabolic processes in the cell (biology), cell need enzyme catalysis in order to occur at rates fast enough to sustain life. Metabolic pathways depend upon enzymes to catalyze individual steps. The study of enzymes is called ''enzymology'' and the field of pseudoenzyme, pseudoenzyme analysis recognizes that during evolution, some enzymes have lost the ability to carry out biological catalysis, which is often reflected in their amino acid sequences and unusual 'pseudocatalytic' properties. Enzymes are known to catalyze more than 5,000 biochemical reaction types. Other biocatalysts include Ribozyme, catalytic RNA molecules, also called ribozymes. They are sometimes descr ...

Germinate
Germination is the process by which an organism grows from a seed or spore. The term is applied to the sprouting of a seedling from a seed of an flowering plant, angiosperm or gymnosperm, the growth of a sporeling from a spore, such as the spores of Fungus, fungi, ferns, bacteria, and the growth of the pollen tube from the pollen grain of a seed plant. Seed plants Germination is usually the growth of a plant contained within a seed resulting in the formation of the seedling. It is also the process of reactivation of metabolic machinery of the seed resulting in the emergence of radicle and plumule. The seed of a vascular plant is a small package produced in a fruit or conifer cone, cone after the union of male and female gamete, reproductive cells. All fully developed seeds contain an embryo and, in most plant species some store of food reserves, wrapped in a seed coat. Dormant seeds are viable seeds that do not germinate because they require specific internal or environ ...

Eastern Hemlock
''Tsuga canadensis'', also known as eastern hemlock, eastern hemlock-spruce, or Canadian hemlock, and in the French-speaking regions of Canada as ''pruche du Canada'', is a coniferous tree native to eastern North America. It is the state tree of Pennsylvania. Eastern hemlocks are widespread throughout much of the Great Lakes region, the Appalachian Mountains, the Northeastern United States, and Maritime Canada. They have been introduced in the United Kingdom and mainland Europe, where they are used as ornamental trees. Eastern hemlock populations in North America are threatened in much of their range by the spread of the invasive Hemlock woolly adelgid, which infests and eventually kills trees. Declines in population from hemlock wooly adelgid infestation have led to ''Tsuga canadensis'' being listed as Near Threatened on the IUCN Red List. Eastern hemlocks are long lived trees, with many examples living for more than 500 years. They can grow to heights of more than , and are to ...

Rainfall
Rain is a form of precipitation where water droplets that have condensed from atmospheric water vapor fall under gravity. Rain is a major component of the water cycle and is responsible for depositing most of the fresh water on the Earth. It provides water for hydroelectric power plants, crop irrigation, and suitable conditions for many types of ecosystems. The major cause of rain production is moisture moving along three-dimensional zones of temperature and moisture contrasts known as weather fronts. If enough moisture and upward motion is present, precipitation falls from convective clouds (those with strong upward vertical motion) such as cumulonimbus (thunder clouds) which can organize into narrow rainbands. In mountainous areas, heavy precipitation is possible where upslope flow is maximized within windward sides of the terrain at elevation which forces moist air to condense and fall out as rainfall along the sides of mountains. On the leeward side of mountains, ...

Philodendron
''Philodendron'' is a large genus of flowering plants in the family Araceae. , the Plants of the World Online accepted 621 species; other sources accept different numbers. Regardless of number of species, the genus is the second-largest member of the family Araceae, after genus ''Anthurium''. Taxonomically, the genus ''Philodendron'' is still poorly known, with many undescribed species. Many are grown as ornamental and indoor plants. The name derives from the Greek words ''philo-'' 'love, affection' and ''dendron'' 'tree'. The generic name, ''Philodendron'', is often used as the English name. Description Growth habit Compared to other genera of the family Araceae, philodendrons have an extremely diverse array of growth methods. The habits of growth can be epiphytic, hemiepiphytic, or rarely terrestrial. Others can show a combination of these growth habits depending on the environment. Hemiepiphytic philodendrons can be classified into two types: primary and secondary hemiepiphy ...

Araceae
The Araceae are a family of monocotyledonous flowering plants in which flowers are borne on a type of inflorescence called a spadix. The spadix is usually accompanied by, and sometimes partially enclosed in, a spathe (or leaf-like bract). Also known as the arum family, members are often colloquially known as aroids. This family of 114 genera and about 3,750 known species is most diverse in the New World tropics, although also distributed in the Old World tropics and northern temperate regions. Description Within the Araceae, species are often rhizomatous or tuberous; many are epiphytic, creeping lianas or vining plants, and the leaves and tissues of the entire plant nearly always contains irritating calcium oxalate crystals or raphides, in varying degrees. The foliage can vary considerably from species to species. The majority of species produce an inflorescence consisting of a spadix (which some compare to a corn cob, in appearance), which is nearly always surrounded ...

Monstera Deliciosa
''Monstera deliciosa'', the Swiss cheese plant or split-leaf philodendron is a species of flowering plant native to tropical forests of southern Mexico, south to Panama. It has been introduced to many tropical areas, and has become a mildly invasive species in Hawaii, Seychelles, Ascension Island and the Society Islands. It is very widely grown in temperate climate, temperate zones as a houseplant. The common name "Swiss cheese plant" is also used for the related species from the same genus, ''Monstera adansonii''. The common name "split-leaf philodendron" is also used for the species ''Thaumatophyllum bipinnatifidum'', although neither species is in the genus ''Philodendron''. Names The Botanical name#Binary name, specific epithet ''deliciosa'' means "delicious", referring to the edible fruit. The genus ''Monstera'' is named from the Latin word for "monstrous" or "abnormal", and refers to the unusual leaf, leaves with natural holes that members of the genus have. Its popular na ...

Vine
A vine is any plant with a growth habit of trailing or scandent (that is, climbing) stems, lianas, or runners. The word ''vine'' can also refer to such stems or runners themselves, for instance, when used in wicker work.Jackson; Benjamin; Daydon (1928). ''A Glossary of Botanic Terms with their Derivation and Accent'', 4th ed. London: Gerald Duckworth & Co. In parts of the world, including the British Isles, the term "vine" usually applies exclusively to grapevines, while the term "climber" is used for all climbing plants. Growth forms Certain plants always grow as vines, while a few grow as vines only part of the time. For instance, poison ivy and bittersweet can grow as low shrubs when support is not available, but will become vines when support is available. A vine displays a growth form based on very long stems. This has two purposes. A vine may use rock exposures, other plants, or other supports for growth rather than investing energy in a lot of supportive tissu ...

Hydrangea Hirta
''Hydrangea hirta'', also known as the nettle-leaved hydrangea, is a species of flowering plant in the family Hydrangeaceae that is native to East Asia. Due to the beauty and sturdiness of the species' flowers it can be found outside of its range being used for horticultural and landscaping purposes, and is found in gardens in countries including the United Kingdom and the United States. Taxonomy ''Hydrangea'' is Greek in origin, and comes from Greek meaning "water" and meaning "vessel" describing to the shape of the cup shaped fruit and the capsule the fruit is contained in. The ''hirta'' portion of this species name means "hairy". Another name for this species is '' Hortensia hirta''. ''Hortensia'' is a Latinised version of the French given name Hortense, referring to the wife of Jean-André Lepaute. In Japan the name for this species is meaning small hydrangea. Natural hybrids between hydrangea species are rare, but these have been found in the Izu Peninsula of Japan betw ...
