Argentina anserina: Argentina anserina is a synonym of "Potentilla anserina" L., the accepted name of a perennial flowering plant in the rose family Rosaceae.  It is known by the common names "silverweed", common silverweed or silverweed cinquefoil.  It is native throughout the temperate Northern Hemisphere, often on river shores and in grassy habitats such as meadows and road-sides.  The plant was originally placed in the genus "Potentilla" by Carl Linnaeus in his Species plantarum, edition 1, (1753) but was reclassified into the resurrected genus "Argentina" by research conducted in the 1990s.  It is a species aggregate which has frequently been divided into multiple species.  The reclassification remains controversial and is not accepted by some authorities.

Filipendula rubra: Filipendula rubra, also known as Queen-of-the-prairie, is a species of flowering plant in the family Rosaceae native to shady and moist habitats throughout northeastern and central United States.  The plant can grow in either sunlight or part shade.  The plant can grow in the shade if the soil is not always kept moist, the shade helps keep the soil from drying out from direct sunlight which causes a quicker evaporation of the water present in the soil.  Filipendula Rubra grows tall and firm, this plant produces blooms that are tiny and pink above its ferny, pointy leaves.

Dryas octopetala: Dryas octopetala (common names include mountain avens, eightpetal mountain-avens, white dryas, and white dryad) is an Arctic–alpine flowering plant in the family Rosaceae.  It is a small prostrate evergreen subshrub forming large colonies.  The specific epithet "octopetala" derives from the Greek "octo" (eight) and "petalon" (petal), referring to the eight petals of the flower, an unusual number in the Rosaceae, where five is the normal number.  However, flowers with up to 16 petals also occur naturally.

A deciduous tree, it includes many varieties of the fruit trees known as plums in English, though not all plums belong to this species.  The greengages and damsons also belong to subspecies of "P. domestica".

Rose: A rose is a woody perennial flowering plant of the genus Rosa, in the family Rosaceae, or the flower it bears.  There are over a hundred species and thousands of cultivars.  They form a group of plants that can be erect shrubs, climbing or trailing with stems that are often armed with sharp prickles.  Flowers vary in size and shape and are usually large and showy, in colours ranging from white through yellows and reds.  Most species are native to Asia, with smaller numbers native to Europe, North America, and northwestern Africa.  Species, cultivars and hybrids are all widely grown for their beauty and often are fragrant.  Roses have acquired cultural significance in many societies.  Rose plants range in size from compact, miniature roses, to climbers that can reach seven meters in height.  Different species hybridize easily, and this has been used in the development of the wide range of garden roses.

Tangqi: Tangqi is a county-level town located on the north side of Hangzhou in China's Zhejiang province, 10 kilometers away from the main city of Hangzhou.  Tangqi was established 1,000 years ago, and it is famous for its unique fruit called Loquat, also the Prunus mume in the neighborhood area of Chaoshan Mountain.

It is a large evergreen shrub growing to 4 m tall and wide.  Clusters of white flowers are followed by masses of small, globose, red fruits (pomes) in autumn.

Amygdaloideae: Amygdaloideae is a subfamily within the flowering plant family Rosaceae.  It was formerly considered by some authors to be separate from Rosaceae, and the family names Prunaceae and Amygdalaceae have been used.  Reanalysis from 2007 has shown that the previous definition of subfamily Spiraeoideae was paraphyletic.  To solve this problem, a larger subfamily was defined that includes the former Amygdaloideae, Spiraeoideae, and Maloideae.  This subfamily, however, is to be called Amygdaloideae rather than Spiraeoideae under the International Code of Nomenclature for algae, fungi, and plants as updated in 2011.
