Magnolia x soulangeana


Magnolia × soulangeana (saucer magnolia) is a hybrid plant in the genus Magnolia and family Magnoliaceae. It is a deciduous tree with large, early-blooming flowers in various shades of white, pink, and purple. It is one of the most commonly used magnolias in horticulture.





Magnolia × soulangeana was initially bred by French plantsman Étienne Soulange-Bodin (1774–1846), a retired cavalry officer in Napoleon's army, at his château de Fromont near Paris. He crossed Magnolia denudata with M. liliiflora in 1820, and was impressed with the resulting progeny's first precocious flowering in 1826.




From France, the hybrid quickly entered cultivation in England and other parts of Europe, and also North America. Since then, plant breeders in many countries have continued to develop this magnolia, and over a hundred named horticultural varieties (cultivars) are now known.








Magnolia × soulangeana flowers are large, commonly 10–20 cm (4–8 in) across, and colored various shades of white, pink, and maroon. An American variety, 'Grace McDade' from Alabama, is reported to bear the largest flowers, with a 35 cm (14 in) diameter, white tinged with pinkish-purple. The exact timing and length of flowering varies between named varieties, as does the shape of the flower. Some are globular, others a cup-and-saucer shape.

Photographing Spring



Spring is the transition period between winter and summer.  It is a time of rebirth, renewal and regrowth.  It is also a season which offers many excellent photographic opportunities. 



In spring, the axis of the Earth is increasing its tilt toward the Sun and the length of daylight rapidly increases for the relevant hemisphere. The hemisphere begins to warm significantly causing new plant growth to "spring forth," giving the season its name. Snow, if a normal part of winter, begins to melt, and streams swell with runoff. Frosts, if a normal part of winter, become less severe. In climates that have no snow and rare frosts, the air and ground temperature increases more rapidly. Many flowering plants bloom this time of year, in a long succession sometimes beginning even if snow is still on the ground, continuing into early summer. In normally snowless areas "spring" may begin as early as February (Northern Hemisphere) heralded by the blooming of deciduous magnolias, cherries, and quince, or August (Southern Hemisphere) in the same way. Subtropical and tropical areas have climates better described in terms of other seasons, e.g. dry or wet, or monsoonal, or cyclonic. Often the cultures have locally defined names for seasons which have little equivalence to the terms originating in Europe. Many temperate areas have a dry spring, and wet autumn (fall), which brings about flowering in this season more consistent with the need for water as well as warmth.

Crocus




Crocus is a genus in the iris family comprising about 80 species of perennials growing from corms.  Many are cultivated from their flowers apperaing in autumn, winter, or spring.  Crocuses are native to woodland, scrub and meadows from sea level to alpine tundra. 






The cup-shaped, solitary, salverform flowers taper off into a narrow tube. Their color varies enormously, although lilac, mauve, yellow and white are predominant.
