                            Pensamiento

                       

                        El pensamiento salvaje (Viola tricolor) es una especie salvaje común de Europa, que crece como anual o de corta vida perenne. Fue introducida en Norteamérica, donde se expandió mucho, conocida como Johnny saltarín (aunque éste es aplicado a similares especies como Viola pedunculata). Es el progenitor del cultivado pensamiento Viola tricolor hortensis; antes de que el pensamiento fuese desarrollado, "pensamiento" era un apelativo alternativo de la forma salvaje.

      
                         Es una pequeña planta de hábito trepador, alcanzando al menos 15 cm de altura, con flores de 15 mm de diámetro. Crece en pastizales bajos, en suelos ácidos o neutrales. Acepta media sombra. Florece borealmente de abril a septiembre; pueden ser púrpuras, azules, amarillas o blancas. Es hermafrodita y autofértil, polinizada por abejas.
                      

Basil

 
 

                                                        basil

                                                         

                                                        Basil (/ˈbæzəl/,^[1] also US: /ˈbeɪzəl/;^[2] Ocimum basilicum), also called great basil, is a culinary herb of the family Lamiaceae (mints).

Basil is native to tropical regions from central Africa to Southeast Asia.^[3] It is a tender plant, and is used in cuisines worldwide. Depending on the species and cultivar, the leaves may taste somewhat like anise, with a strong, pungent, often sweet smell.

There are many varieties of basil, as well as several related species or hybrids also called basil. The type used commonly as a flavor is typically called sweet basil (or Genovese basil), as opposed to Thai basil (O. basilicum var. thyrsiflora), lemon basil (O. × citriodorum), and holy basil (Ocimum tenuiflorum). While most common varieties of basil are treated as annuals, some are perennial in warm, tropical climates, including holy basil and a cultivar known as "African blue basil".

   Basil is an annual, or sometimes perennial, herb used for its leaves. Depending on the variety, plants can reach between 30 cm (0.98 ft) and 150 cm (4.9 ft). Its leaves are richly green and ovate, but otherwise come in a wide variety of sizes and shapes depending on cultivar. Leaf sizes range from 3 cm (1.2 in) to 11 cm (4.3 in) long, and between 1 cm (0.39 in) and 6 cm (2.4 in) wide. Basil grows a thick, central taproot. Its flowers are small and white, and grow from a central inflorescence that emerges from the central stem atop the plant.^{[citation needed]}                                                                           

poinsetta

                                     

                                      Poinsetta    

                                                     The poinsettia (/pɔɪnˈsɛtiə/ or /pɔɪnˈsɛtə/)^[1][2] (Euphorbia pulcherrima) is a commercially important plant species of the diverse spurge family (Euphorbiaceae). Indigenous to Central America, it was described as a new species in 1834. It is particularly well known for its red and green foliage and is widely used in Christmas floral displays. It derives its common English name from Joel Roberts Poinsett, the first United States Minister to Mexico, who is credited with introducing the plant to the US in the 1820s. Poinsettias are shrubs or small trees, with heights of 0.6–4 m (2.0–13.1 ft). Though often stated to be highly toxic, the poinsettia is not dangerous to pets or children. Exposure to the plant, even consumption, most often results in no effect, though it can cause nausea, vomiting, or diarrhea.

                                      Euphorbia pulcherrima is a shrub or small tree, typically reaching a height of 0.6–4 metres (2–13 ft). The plant bears dark green dentate leaves that measure 7–16 centimetres (2.8–6.3 in) in length. The colored bracts—which are most often flaming red but can be orange, pale green, cream, pink, white, or marbled—are often mistaken for flower petals because of their groupings and colors, but are actually leaves.^[9][10] The colors of the bracts are created through photoperiodism, meaning that they require darkness (at least fourteen hours at a time for 6–8 weeks in a row) to change color. The plants also require abundant light during the day for the brightest color.^[11]

The flowers of the poinsettia are unassuming and do not attract pollinators. They are grouped within the cyathia (small yellow structures found in the center of each leaf bunch, or false flowers).^[9] Nothing is known about pollination in wild poinsettias, though wasps are noted to occasionally visit the cyathia.^[12]

                        

grass

                                                Grasess

                                           

                                                        

                                              rushes (Juncaceae).^[1] These three families are not closely related but belong to different clades in the order Poales.

The true grasses include cereals, bamboo and the grasses of lawns (turf) and grassland. Uses for graminoids include food (as grain, sprouted grain, shoots or rhizomes), drink (beer, whisky), pasture for livestock, thatching thatch, paper, fuel, clothing, insulation, construction, sports turf, basket weaving and many others.

Many grasses are short, but some grasses, like bamboo can grow very tall. Plants from the grass family can grow in many places, even if they are very cold or very dry. Several other plants that look similar but are not members of the grass family are also sometimes called.

                                                                     

                                                                    Grass is a monocotyledon plant, herbaceous plants with narrow leaves growing from the base. A common kind of grass is used to cover the ground in a lawn and other places. The grasses include the "true grasses", of the family Poaceae (also called Gramineae), as well as the sedges (Cyperaceae) and the rushes (Juncaceae).
