TODAY'S FLOWERS - Begonia - Begoniaceae, Begonien - Schiefblatt

Flowers from around the world can be viewed here:
Begonia is a genus in the flowering plant family Begoniaceae.
The only other member of the family Begoniaceae is Hillebrandia, a genus with a single species in the Hawaiian Islands. The genus Symbegonia is now included in Begonia. "Begonia" is the common name as well as the generic name for all members of the genus.
The genus name coined by Charles Plumier French patron of botany honours Michel Bégon,
a former governor of the French colony of Haiti.
Because of their sometimes showy flowers of white, pink, scarlet or yellow color and often attractively marked leaves, many species and innumerable hybrids and cultivars are cultivated. The genus is unusual in that species throughout the genus, even those coming from different continents, can frequently be hybridized with each other, and this has led to an enormous number of cultivars. The American Begonia Society classifies begonias into several major groups:
cane-like, shrub-like, tuberous, rhizomatous, semperflorens, rex, trailing-scandent,
or thick-stemmed.

Begonien (Begonia), auch Schiefblatt genannt, sind eine Gattungaus der Familie der Schiefblattgewächse (Begoniaceae).

Insgesamt werden etwa 1400 bis 1500 Arten dieser Gattung zugeordnet.
Viele Arten und Sorten der Begonien werden wegen ihres farbenprächtigen Laubes oder ihrer eindrucksvollen Blüten als Zierpflanzen in Räumen oder als Beet- und Balkonpflanzen gepflegt.
Der Gattungsnamen ehrt Michel Bégon, einen Reisegefährten des Botanikers Charles Plumier.

Weit verbreitet als Zierpflanzen sind verschiedene Gruppen von Hybriden.
Begonia-Semperflorens-Hybriden oder Eisbegonien genannt,
Elatior-Begonien (Begonia ×hiemalis Fotsch, Syn.: Begonia ×elatior hort., Begonia-Elatior-Hybriden) Knollenbegonien (Begonia-Tuberhybrida)
Lorrainebegonien (Lorrainebegonien-Hybriden), wurden früher öfter angeboten, heute kaum zu finden. Rex-Begonien (Begonia-Rex-Hybriden)

Amelanchier - Serviceberry trees and shrubs

Infested ash treeToronto's war with the emerald ash borer resumes next month, when the bug will come out of the woodwork, literally, for mating season.
The metallic green beetle, which has killed more than one million trees in southwestern Ontario, was discovered in Toronto in 2007 and has since infested 6% of the city's street trees -- about 27,000 ashes. It is expected to demolish the city's ash trees in the next 10 years.

We have four very large, mature ash trees around our house. Providing much needed shade during the hot summer month. If we loose our trees because of the emerald ash borer, it is time to plant new trees and shrubs around the house.

We have selected the serviceberry tree for our backyard.

Amelanchier, also known as shadbush, serviceberry, sarvisberry, juneberry, Saskatoon, shadblow, shadwood, sugarplum, and wild-plum, is a genus of about 20 species of shrubs and small deciduous trees in the Rosaceae (Rose family).
The genus is native to temperate regions of the Northern Hemisphere, growing primarily in early successional habitats. It is most diverse taxonomically in North America, especially in the northern United States and southern Canada, and is native to every state of the United States except Hawaii. Two species also occur in Asia, and one in Europe.
The origin of the generic name Amelanchier is probably derived from the Provençal name of the European Amelanchier ovalis. The name serviceberry comes from the similarity of the fruit to the related European Sorbus.
Juneberry refers to the fruits of certain species becoming ripe in June.
The name Saskatoon originated from a Cree Indian noun misâskwatômina (misāskwatōmina, misaaskwatoomina) for Amelanchier alnifolia. The city of Saskatoon, Saskatchewan is named after this plant.

These plants are valued horticulturally, and their fruits are important to wildlife.

Die Gattung Amelanchier (Felsenbirne) umfasst 25 Arten, die fast alle in Nordamerika verbreitet sind.
Zwei Arten sind in Europa bis Kleinasien und zwei Arten sind in Asien beheimatet.
Als Ziersträucher werden in Mitteleuropa die Arten Amelanchier lamarckii, Amelanchier laevis und Amelanchier ovalis und deren Sorten gehandelt.
Der botanische Gattungsname Amelanchier leitet sich ab von der französisch-provencalischen Bezeichnung „amelanche“ für die Früchte der dort heimischen Amelanchier ovalis. Das Wort „amelanche“ ist keltisch-gallischen Ursprungs und bedeutet nichts anderes als „Äpfelchen“. Die erste schriftliche Erwähnung von Amelanchier datiert aus dem Jahre 1549.
