A shrub or bush is distinguished from a tree A tree is a perennial woody plant. It is most often defined as a woody plant that has many secondary branches supported clear of the ground on a single main stem or trunk with clear apical dominance. A minimum height specification at maturity is cited by some authors, varying from 3 m to 6 m; some authors set a minimum of 10 cm trunk diameter by its multiple stems and lower height Height is the measurement of vertical distance, but has two meanings in common use. It can either indicate how "tall" something is, or how "high up" it is. For example one could say "That is a tall building", or "That airplane is high up in the sky". These can both be referred to as the height of the object,, usually less than 5–6 m (15–20 ft) tall. A large number of plants can be either shrubs or trees, depending on the growing conditions they experience. Small, low shrubs such as lavender The lavenders are a genus of 39 species of flowering plants in the mint family, Lamiaceae. An Old World genus, distributed from Macaronesia (Cape Verde and Canary Islands and Madeira) across Africa, the Mediterranean, South-West Asia, Arabia, Western Iran and South-East India. It is thought the genus originated in Asia but is most diversified in, periwinkle Vinca is a genus of six species in the family Apocynaceae, native to Europe, northwest Africa and southwest Asia. The name is pronounced /ˈvɪŋkə/, deriving from Latin vincire: "to bind, fetter". The English name periwinkle is shared with the related genus Catharanthus and thyme Ancient Egyptians used thyme for embalming. The ancient Greeks used it in their baths and burnt it as incense in their temples, believing that thyme was a source of courage. It was thought that the spread of thyme throughout Europe was thanks to the Romans, as they used it to purify their rooms and to "give an aromatic flavour to cheese and are often termed subshrubs A subshrub is a short woody plant. Prostrate shrub is a similar term.

An area of cultivated In agriculture, cultivation is the process of growing plants on arable land. It is usually associated with large-scale agriculture, as opposed to small-scale gardening. Crop cultivation requires fertile soil, water (from irrigation or precipitation), and seeds. Cultivation involves the sowing of the seeds in the appropriate season. In the process shrubs in a park A park is a protected area, in its natural or semi-natural state, or planted, and set aside for human recreation and enjoyment, or for the protection of wildlife or natural habitats. It may consist of rocks, soil, water, flora and fauna and grass areas or garden A garden is a planned space, usually outdoors, set aside for the display, cultivation, and enjoyment of plants and other forms of nature. The garden can incorporate both natural and man-made materials. The most common form today is known as a residential garden, but the term garden has traditionally been a more general one. Zoos, which display is known as a shrubbery A shrubbery is a wide border to a garden where shrubs are thickly planted; or a similar larger area with a path winding through it. A shrubbery was a feature of 19th-century gardens in the English manner, with its origins in the gardenesque style of the early part of the century. A shrubbery was a collection of hardy shrubs, quite distinct from a. When clipped as topiary Topiary is the art of creating sculptures in the medium of clipped trees, shrubs and sub-shrubs. The word derives from the Latin word for an ornamental landscape gardener, topiarius, creator of topia or "places", a Greek word that Romans applied also to fictive indoor landscapes executed in fresco. No doubt the use of a Greek word, shrubs generally have dense foliage In botany, a leaf is an above-ground plant organ specialized for photosynthesis. For this purpose, a leaf is typically flat and thin. As an evolutionary trait, the flatness of leaves works to expose the chloroplasts to more light and to increase the absorption of carbon dioxide at the expense of water loss. In the Devonian period, when carbon and many small leafy branches A branch or tree branch (sometimes referred to in botany as a ramus) is a woody structural member connected to but not part of the central trunk of a tree (or sometimes a shrub). Large branches are known as boughs and small branches are known as twigs growing close together. Many shrubs respond well to renewal pruning Pruning is an horticultural practice involving the selective removal of parts of a plant, such as branches, buds, or roots. Reasons to prune plants include deadwood removal, shaping , improving or maintaining health, reducing risk from falling branches, preparing nursery specimens for transplanting, and both harvesting and increasing the yield or, in which hard cutting back to a 'stool A living stump is created when a live tree is cut and its stump remains in the ground. The stump and root system may remain alive for several years if its roots graft to nearby living trees. A living stump capable of producing sprouts or cuttings is known as a stool, and is used in the coppicing method of woodland management' results in long new stems A stem is one of two main structural axes of a vascular plant. The stem is normally divided into nodes and internodes, the nodes hold buds which grow into one or more leaves, inflorescence , cones or other stems etc. The internodes distance one node from another. The term shoots is often confused with stems; shoots generally refer to new fresh known as "canes". Other shrubs respond better to selective pruning to reveal their structure and character.

Shrubs in common garden practice are generally broad-leaved plants The flowering plants , also known as Angiospermae or Magnoliophyta, are the most diverse group of land plants. Together with gymnosperms, they are the only extant groups of seed-producing plants, but they can be distinguished from the gymnosperms by a series of synapomorphies (derived characteristics). These characteristics include flowers,, though some smaller conifers The conifers, division Pinophyta, also known as division Coniferophyta or Coniferae, are one of 13 or 14 division level taxa within the Kingdom Plantae. Pinophytes are gymnosperms. They are cone-bearing seed plants with vascular tissue; all extant conifers are woody plants, the great majority being trees with just a few being shrubs. Typical such as Mountain Pine Mountain Pine or Mugo Pine is a high-altitude European pine, found in the Pyrenees, Alps, Erzgebirge, Carpathians, northern Apennines and Balkan Peninsula mountains from (mostly) 1,000 m to 2,200 m, occasionally as low as 200 m in the north of the range in Germany and Poland, and as high as 2,700 m in the south of the range in Bulgaria or in the and Common Juniper Juniperus communis, the Common Juniper, is a species in the genus Juniperus, in the family Cupressaceae. It has the largest range of any woody plant, throughout the cool temperate Northern Hemisphere from the Arctic south in mountains to around 30°N latitude in North America, Europe and Asia are also shrubby in structure. Shrubs can be either deciduous Deciduous means falling off at maturity or tending to fall off and is typically used in reference to trees or shrubs that lose their leaves seasonally and to the shedding of other plant structures such as petals after flowering or fruit when ripe. In a more specific sense deciduous means the dropping of a part that is no longer needed, or falling or evergreen In botany, an evergreen plant is a plant that has leaves in all seasons. This contrasts with deciduous plants, which completely lose their foliage during winter.

Shrubs as a botanical structural form

Main article: shrubland Shrubland, scrubland, scrub or brush is a plant community characterized by vegetation dominated by shrubs, often also including grasses, herbs, and geophytes. Shrubland may either occur naturally or be the result of human activity. It may be the mature vegetation type in a particular region and remain stable over time, or a transitional community

In botany and ecology Ecology is the scientific study of the distributions, abundance and relations of organisms and their interactions with the environment. Ecology includes the study of plant and animal populations, plant and animal communities and ecosystems. Ecosystems describe the web or network of relations among organisms at different scales of organization a shrub is more specifically used to describe the particular physical structural In biology, the canopy is the aboveground portion of a plant community or crop, formed by plant crowns or plant life-form of woody plants which are less than 8 m high and usually have many stems arising at or near the base.

For example, a descriptive system widely adopted in Australia For at least 40,000 years before European settlement in the late 18th century, Australia was inhabited by indigenous Australians, who belonged to one or more of the roughly 250 language groups. After sporadic visits by fishermen from the immediate north and discovery by Dutch explorers in 1606, Australia's eastern half was claimed by the British is based on structural characteristics based on life-form, plus the height and amount of foliage cover of the tallest layer or dominant species In biology, a species is one of the basic units of biological classification and a taxonomic rank. A species is often defined as a group of organisms capable of interbreeding and producing fertile offspring. While in many cases this definition is adequate, more precise or differing measures are often used, such as based on similarity of DNA or.[1]

When should a golden privet shrub start leafing out in zone 5?
Q. We have a golden privet shrub that's about 7 years old, under a Norway Maple. Just the very bottom of the shrub has leaves so far - is this a goner or is it too soon to tell? I'm located outside Chicago in Zone 5. Thank you!

A. I'm in zone 6, my privet is under a silver maple and it's just starting to get leafy now...So I'd say wait.
