Hydrangeas
''Hydrangea'', () commonly named the hortensia, is a genus of over 75 species of flowering plants native to Asia and the Americas. By far the greatest species diversity is in eastern Asia, notably China, Korea, and Japan. Most are shrubs tall, but some are small trees, and others lianas reaching up to by climbing up trees. They can be either deciduous or evergreen, though the widely cultivated temperate species are all deciduous. ''Hydrangea'' is derived from Greek and means ‘water vessel’ (from ''húdōr'' "water" + ''ángos'' or ''angeîon'' "vessel"), in reference to the shape of its seed capsules. The earlier name, ''Hortensia'', is a Latinised version of the French given name Hortense, honoring French astronomer and mathematician Nicole-Reine Hortense Lepaute. This claim is disputed in page 88 on citation 10 at Nicole-Reine Hortense Lepaute page, which says: "Larousse considers this an injustice, and remarks that it has led many persons to the erroneous notion tha ...

Hydrangea Arborescens
''Hydrangea arborescens'', commonly known as smooth hydrangea, wild hydrangea, sevenbark, or in some cases, sheep flower, is a species of flowering plant in the family Hydrangeaceae. It is a small- to medium-sized, multi-stemmed, deciduous shrub up to tall that is native to the eastern United States. Description The inflorescence is a corymb up to wide. Showy, sterile flowers are usually absent or if present they are usually less than 1 cm in diameter on the edge of the panicles. Flowering occurs May to July. Fruit is a ribbed, brown capsule about 2 mm long. Many are produced in October and persist through the winter. The leaves are large (8 to 18 cm long), opposite, serrated, ovate, and deciduous. The lower leaf surface is glabrous or with inconspicuous fine hairs, appearing green; trichomes of the lower surface are restricted to the midrib and major veins. The stem bark has a peculiar tendency to peel off in several successive thin layers with diffe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydrangea Cinerea
''Hydrangea cinerea'', the ashy hydrangea or gray hydrangea, is a small to medium sized, deciduous shrub up to 3 m tall; its natural range is interior regions of the southeastern United States.Lance, Ron. 2004 Woody Plants of the southeastern United States: A winter guide. The University of Georgia Press. 456 p. Its common names reflect the ashy or gray appearance of the undersides of its leaves, which results from a dense pubescence. Range and habitat Ashy hydrangea occurs scattered in mostly upland sites and rocky outcrops in the interior regions of the southeastern United States in the southern sections of the Blue Ridge Mountains from Tennessee to South Carolina, west to Missouri, south to Arkansas, Alabama, and Georgia. It is typically found in neutral, basic or calcareous soils. Taxonomy Ashy hydrangea is similar to the more widespread smooth hydrangea (''Hydrangea arborescens'') and the restricted silverleaf hydrangea (''Hydrangea radiata''). At one time both as ...

Hydrangea Aspera
''Hydrangea aspera'' is a species of flowering plant in the family Hydrangeaceae, native to the region between the Himalayas, across southern China, to Taiwan. It is a large, erect deciduous shrub growing to tall and wide, with broadly oval leaves. The flowers are typically borne in large flat heads in late summer, and are in variable shades of pale blue and pink, fringed by white or pale pink sterile florets. The Latin ''aspera'' means "rough-textured" and refers to the downy lower surface of the leaves. Cultivation The plant is widely cultivated, and favours a sheltered position in acid or neutral soil, with best growth often in partial or afternoon shade. The leaves, in some forms exceeding 30.5 cm (12 inches) long, are vulnerable to drying winds as well as mechanical wind damage. Numerous cultivars have been produced as ornamental subjects for parks and gardens. They include: * 'Anthony Bullivent' * 'Longipes' * 'Mauvette' * 'Peter Chappell' * 'The Ditch' In additio ...

Hydrangea Anomala
''Hydrangea anomala'', the Japanese climbing-hydrangea, is a species of flowering plant in the family Hydrangeaceae native to the woodlands of the Himalaya, southern and central China and northern Myanmar. It is a woody climbing plant, growing to 12 m height up trees or rock faces, climbing by means of small aerial roots on the stems. The leaves are deciduous, ovate, 7–13 cm long and 4–10 cm broad, with a heart-shaped base, coarsely serrated margin and acute apex. The flowers are produced in flat corymbs 5–15 cm diameter in mid-summer; each corymb includes a small number of peripheral sterile white flowers 2–3.5 cm across, and numerous small, creamy-white fertile flowers 1–2 mm diameter. The fruit is a dry urn-shaped capsule 3–5 mm diameter containing several small winged seeds. The closely related ''Hydrangea petiolaris'' from eastern Siberia, Japan, and Korea, is sometimes treated as a subspecies of ''H. anomala''; it differ ...

Flower Pigment
Biological pigments, also known simply as pigments or biochromes, are substances produced by living organisms that have a color resulting from selective Absorption (electromagnetic radiation), color absorption. Biological pigments include plant pigments and flower pigments. Many biological structures, such as skin, eyes, feathers, fur and hair contain pigments such as melanin in specialized cells called chromatophores. In some species, pigments accrue over very long periods during an individual's lifespan. Pigment color differs from structural color in that it is the same for all viewing angles, whereas structural color is the result of selective Reflection (physics), reflection or iridescence, usually because of multilayer structures. For example, butterfly wings typically contain structural color, although many butterflies have cells that contain pigment as well. Biological pigments See conjugated systems for electron bond chemistry that causes these molecules to have pigm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soil PH
Soil pH is a measure of the acidity or basicity (alkalinity) of a soil. Soil pH is a key characteristic that can be used to make informative analysis both qualitative and quantitatively regarding soil characteristics. pH is defined as the negative logarithm (base 10) of the activity of hydronium ions ( or, more precisely, ) in a solution. In soils, it is measured in a slurry of soil mixed with water (or a salt solution, such as ), and normally falls between 3 and 10, with 7 being neutral. Acid soils have a pH below 7 and alkaline soils have a pH above 7. Ultra-acidic soils (pH 9) are rare. Soil pH is considered a master variable in soils as it affects many chemical processes. It specifically affects plant nutrient availability by controlling the chemical forms of the different nutrients and influencing the chemical reactions they undergo. The optimum pH range for most plants is between 5.5 and 7.5; however, many plants have adapted to thrive at pH value ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
