Lammas Growth
Lammas growth, also called Lammas leaves, Lammas flush, second shoots, or summer shoots, is a season of renewed growth in some trees in temperate regions put on in July and August (if in the northern hemisphere, January and February if in the southern), that is around Lammas day, August 1. It can occur in both hardwoods and softwoods. Examples of common trees which exhibit regrowth are oak, ash, beech, sycamore, yew, scots pine, sitka spruce, poplar and hawthorn. This secondary growth may be an evolutionary strategy to compensate for leaf damage caused by insects during the spring. It is not present in birch or willow Willows, also called sallows and osiers, of the genus ''Salix'', comprise around 350 species (plus numerous hybrids) of typically deciduous trees and shrubs, found primarily on moist soils in cold and temperate regions. Most species are known .... Lammas growth declines with the age of the tree, being most vigorous and noticeable in young trees. It di ...

Lammas Growth On Q
Lammas (from Old English ''hlāfmæsse'', "loaf-mass"), also known as Loaf Mass Day, is a Christian holiday celebrated in some English-speaking countries on 1 August. The name originates from the word "loaf" in reference to bread and "Mass" in reference to the Eucharist. It is a festival in the liturgical calendar to mark the blessing of the First Fruits of harvest, with a loaf of bread being brought to the church for this purpose. Lammastide falls at the halfway point between the summer solstice and the autumn equinox. Christians also have church processions to bakeries, where those working therein are blessed by Christian clergy. While Lammas is traditionally a Christian holy day, some neopagans have adopted the name and date for one of their harvest festivals in their Wheel of the Year. It is also the same date as the Gaelic harvest festival Lughnasadh. Name The name 'Lammas' comes from Old English meaning "loaf mass". Several antiquarians suggested that the name 'Lamm ...

Temperate
In geography, the temperate climates of Earth occur in the middle latitudes (approximately 23.5° to 66.5° N/S of the Equator), which span between the tropics and the polar regions of Earth. These zones generally have wider temperature ranges throughout the year and more distinct seasonal changes compared to tropical climates, where such variations are often small; they usually differ only in the amount of precipitation. In temperate climates, not only do latitude, latitudinal positions influence temperature changes, but various sea currents, prevailing wind direction, continentality (how large a landmass is) and altitude also shape temperate climates. The Köppen climate classification defines a climate as "temperate" C, when the mean temperature is above but below in the coldest month to account for the persistence of frost. However, some adaptations of Köppen set the minimum at . Continental climate, Continental climates are classified as D and considered to be varie ...

Fraxinus
''Fraxinus'' (), commonly called ash, is a genus of plants in the olive and lilac family, Oleaceae, and comprises 45–65 species of usually medium-to-large trees, most of which are deciduous trees, although some Subtropics, subtropical species are evergreen trees. The genus is widespread throughout much of Europe, Asia, and North America. The leaves are opposite leaves, opposite (rarely in Whorl (botany), whorls of three), and mostly pinnate, pinnately compound, though simple in a few species. The seeds, popularly known as "keys" or "helicopter seeds", are a type of fruit known as a samara (fruit), samara. Some ''Fraxinus'' species are Dioecy, dioecious, having male and female flowers on separate plants but sex in ash is expressed as a continuum between male and female individuals, dominated by unisexual trees. With age, ash may change their sexual function from predominantly male and hermaphrodite towards femaleness; if grown as an ornamental and both sexes are present, ashes ...

Beech
Beech (genus ''Fagus'') is a genus of deciduous trees in the family Fagaceae, native to subtropical (accessory forest element) and temperate (as dominant element of Mesophyte, mesophytic forests) Eurasia and North America. There are 14 accepted species in two distinct subgenera, ''Englerianae'' and ''Fagus''. The subgenus ''Englerianae'' is found only in East Asia, distinctive for its low branches, often made up of several major trunks with yellowish bark. The better known species of subgenus ''Fagus'' are native to Europe, western and eastern Asia and eastern North America. They are high-branching trees with tall, stout trunks and smooth silver-grey bark. The European beech ''Fagus sylvatica'' is the most commonly cultivated species, yielding a utility timber used for furniture construction, flooring and engineering purposes, in plywood, and household items. The timber can be used to build homes. Beechwood makes excellent firewood. Slats of washed beech wood are spread around ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Taxus
''Taxus'' is a genus of coniferous trees or shrubs known as yews in the family Taxaceae. Yews occur around the globe in temperate zones of the northern hemisphere, northernmost in Norway and southernmost in the South Celebes. Some populations exist in tropical highlands. The oldest known fossil species are from the Early Cretaceous. Morphology They are relatively slow-growing and can be very long-lived, and reach heights of , with trunk girth averaging . They have reddish bark, lanceolate, flat, dark-green leaves long and broad, arranged spirally on the stem, but with the leaf bases twisted to align the leaves in two flat rows either side of the stem. The male cones are globose, across, and shed their pollen in early spring. Yews are mostly dioecious, but occasional individuals can be variably monoecious, or change sex with time. The seed cones are highly modified, each cone containing a single seed long partly surrounded by a modified scale which develops into a soft ...
