Orchid

Orchidaceae, commonly referred to as the Orchid family, is a morphologically diverse and widespread family of monocots. It is currently believed to be the second largest family of flowering plants (only the Asteraceae is larger), with between 21 950 and 26 049 currently accepted species, found in 880 genera. The family also includes Vanilla (the genus of the vanilla plant), Orchis (type genus) and many commonly cultivated plants like some Phalaenopsis or Cattleya.

Baobab

Baobab is the common name of a genus (Adansonia) containing eight species of trees, native to Madagascar (having six species), mainland Africa and Australia (one species in each).

The species reach heights of 5–30 m and trunk diameters of 7-11 m. A specimen in Limpopo Province, South Africa, often considered the largest and oldest example alive, has a circumference of 50 m and an average diameter of 15 m, and coul be about 2 200 years old.

Adansonia grandidieri (Grandidier's Baobab), the most famous of Madagascar’s six baobabs, is an endangered species. It is endemic to Madagascar.

Baobabs store water inside the swollen trunk (up to 120 000 liters) to endure the harsh drought conditions particular to each region.

Sunflower

The sunflower is an annual plant native to the Americas in the family Asteraceae, with a large flowering head. The stem of the flower can grow as high as 3 metres tall, with the flower head reaching up to 30 cm in diameter with the "large" seeds. The term "sunflower" is also used to refer to all plants of the genus Helianthus, many of which are perennial plants.

And here is perhaps the most known artistic representation of sunflowers by a painter, Vincent Van Gogh :

Lily of the Valley


Fruits

Convallaria majalis, commonly known as the Lily of the Valley or Prolificans Lily-of-the-Valley, is one of two members of the genus Convallaria in the flowering plant family Ruscaceae. It is a woodland plant that is native throughout the cool temperate Northern Hemisphere in Asia and Europe and a small native population in eastern North America (Convallaria majalis var. montana.) It is a herbaceous perennial plant that forms extensive colonies by spreading underground stems called rhizomes. These send up numerous stems each spring. The stems grow to 15-30 cm tall, with two leaves 10-25 cm long, and a raceme of 5-15 flowers on the stem apex. The flowers are white (rarely pink), bell-shaped, 5-10 mm diameter, and sweetly scented; flowering is in late spring, in mild winters in early March. The fruit is a small orange-red berry 5-7 mm diameter that contains a few large whitish colored seeds.
