Hardhack
''Spiraea tomentosa'', commonly known as steeplebush, meadowsweet, or hardhack, or eastern hardhack, is a flowering plant native to the eastern United States and Canada. Description ''Spiraea tomentosa'' grows to up to four feet high and prefers moist to wet soil and full sun. It blooms in summer. Each tiny, pink flower is about 1/16 of an inch wide and arranged in narrow, pyramid-shaped flowerheads that grow up to eight inches long. The flowers are followed by small, dry, brown fruit. The specific epithet ''tomentosa'' refers to the undersides of the leaves and the stems, which are covered in a dense white-woolly tomentum. It has similar characteristics to '' Spiraea douglasii''. Ecology The plant bug '' Plagiognathus fuscosus'' breeds on steeplebush. Many bees visit the flowers: ''Apis mellifera'' (non-native), ''Bombus griseocollis'', '' Bombus impatiens'', ''Lasioglossum atwoodi'', ''Lasioglossum hitchensi'', and ''Hylaeus mesillae''. Uses Steeplebush is noted for its ast ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spiraea Douglasii
''Spiraea douglasii'' is a species of flowering plant in the rose family native to western North America. Common names include hardhack, hardhack steeplebush, Douglas' spirea, douglasspirea, steeplebush, and rose spirea. Description ''Spiraea douglasii'' is a woolly shrub growing tall from rhizomes, forming dense riverside thickets. The leaves are long and toothed toward the tips. They are alternately arranged, and the undersides are whitish with prominent veins. Large clusters of small, deep pink flowers form spires in early summer, later turning dark and persisting. The seeds are long and are dispersed by animals and strong winds. Distribution and habitat The plant is native to western North America from Alaska across southwestern Canada and the Pacific Northwest. It has spread to many other places as an invasive species. It was introduced to Europe as early as 1803, and is considered to be especially invasive in Denmark and Latvia. It is also found in France, Ire ...

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wild Flowers Worth Knowing
''Wild Flowers Worth Knowing'' is a book published in 1917 (and republished in 1922) as a result of an adaptation by Asa Don Dickinson of Neltje Blanchan's earlier work '' Nature's Garden'' (1900). Scope It covers mostly North American species, with a sprinkling of cosmopolitans, and includes a preface by Blanchan (who died in 1918). The book, along with ''Birds Worth Knowing'' (also by Blanchan), and other books such as ''Animals Worth Knowing'', was part of the ''Little Nature Library'' series published by Blanchan's husband Frank Nelson Doubleday.Shearin, Gloria. 2008Neltje Blanchan.In: Patterson, D., Thompson, R., Bryson, S., ''et al.'', ''Early American Nature Writers''.

Hardiness Zone
A hardiness zone is a geographic area defined as having a certain average annual minimum temperature, a factor relevant to the survival of many plants. In some systems other statistics are included in the calculations. The original and most widely used system, developed by the United States Department of Agriculture (USDA) as a rough guide for landscaping and gardening, defines 13 zones by long-term average annual extreme minimum temperatures. It has been adapted by and to other countries (such as Canada) in various forms. Unless otherwise specified, in American contexts "hardiness zone" or simply "zone" usually refers to the USDA scale. For example, a plant may be described as "hardy to zone 10": this means that the plant can withstand a minimum temperature of 30 °F (−1.1 °C) to 40 °F (4.4 °C). Other hardiness rating schemes have been developed as well, such as the UK Royal Horticultural Society and US Sunset Western Garden Book systems. A heat zone (s ...

They are highly variable in size, coloration, and sculpture; among the more unusual variants, some are cleptoparasites, some are nocturnal, and some are oligolectic. Most ''Lasioglossum'' species nest in the ground, but some nest in rotten logs. Social behavior among species of ''Lasioglossum'' is extraordinarily variable; species are known to exhibit solitary nesting, primitive eusociality, and social parasitism. Colony sizes vary widely, from small colonies of a single queen four or fewer workers to large colonies of >400 workers and perennial life cycles. The genus ''Lasioglossum'' can be divided ...

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bombus Impatiens
''Bombus impatiens'', the common eastern bumble bee, is the most commonly encountered bumblebee across much of eastern North America. They can be found in the Eastern temperate forest region of the eastern United States, southern Canada, and the eastern Great Plains. Because of their great adaptability, they can live in country, suburbs, and even urban cities. This adaptability makes them a great pollinator species, leading to an increase in their commercial use by greenhouse industry. This increase consequently led to their farther spread outside their previous distribution range. They are considered one of the most important species of pollinator bees in North America. Taxonomy and phylogeny The generic epithet (the first part of the name) ''Bombus'' comes from the genus ''Bombus'', which is also commonly known as bumblebee and belongs to the tribe ''Bombini''. The specific name (the latter half of its scientific name) may come from the flowers of the genus '' Impatiens, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
