Echium Simplex
''Echium simplex'', commonly known as tower of jewels, is a herbaceous biennial plant which grows up to 3m in height. Habitat It is a frost intolerant species requiring sustained periods of sunlight to thrive. It is endemic in the island of Tenerife mainly in Macizo de Anaga. Description The plant is biennial producing a dense rosette in the first year and producing the distinctive inflorescence to a height of during the second year. The flowers are white and the plant is in bloom from February to April in Tenerife. ''E. simplex'' is widely available as a garden flower in warm temperate areas. It is very attractive to bees and produces a distinctively flavoured honey.

Biennial Plant
A biennial plant is a flowering plant that, generally in a temperate climate, takes two years to complete its biological life cycle. Life cycle In its first year, the biennal plant undergoes primary growth, during which its vegetative structures (leaves, stems, and roots) develop. Usually, the stem of the plant remains short and the leaves are low to the ground, forming a rosette. After one year's growing season, the plant enters a period of dormancy for the colder months. Many biennials require a cold treatment, or vernalization, before they will flower. During the next spring or summer, the stem of the biennial plant elongates greatly, or "bolts". The plant then flowers, producing fruits and seeds before it finally dies. There are far fewer biennials than either perennial plants or annual plants. Biennials do not always follow a strict two-year life cycle and the majority of plants in the wild can take 3 or more years to fully mature. Rosette leaf size has been found to ...

Tenerife
Tenerife (; ; formerly spelled ''Teneriffe'') is the largest and most populous island of the Canary Islands. It is home to 43% of the total population of the Archipelago, archipelago. With a land area of and a population of 978,100 inhabitants as of January 2022, it is also the most populous island of Spain and of Macaronesia. Approximately five million tourists visit Tenerife each year; it is the most visited island in the archipelago. It is one of the most important tourist destinations in Spain and the world, hosting one of the world's largest carnivals, the Carnival of Santa Cruz de Tenerife. The capital of the island, , is also the seat of the island council (). That city and are the co-capitals of the autonomous community of the Canary Islands The Canary Islands (; es, Canarias, ), also known informally as the Canaries, are a Spanish autonomous community and archipelago in the Atlantic Ocean, in Macaronesia.

Macizo De Anaga
Macizo de Anaga is a mountain range in the northeastern part of the island of Tenerife in the Canary Islands. The highest point is 1,024 m (Cruz de Taborno). It stretches from the Punta de Anaga in the northeast to Cruz del Carmen in the southwest. Anaga features the mountain peaks of Bichuelo, Anambro, Chinobre, Pico Limante, Cruz de Taborno and Cruz del Carmen. The mountains were formed by a volcanic eruption about 7 to 9 million years ago making it the oldest part of the island. Since 1987 it has been protected as a "natural park", reclassified as "rural park" in 1994. Since 2015 it is also an UNESCO Biosphere Reserve and is the place that has the largest number of endemic species in Europe. It is a remote and wild area characterized by humid forests, such as '' laurisilva''. Native plant species include ''Ceropegia dichotoma'', ''Ceropegia fusca'' and ''Echium virescens''. The Macizo de Anaga is also rich in archaeological finds, among which is the Mummy of San Andrés ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flower
A flower, sometimes known as a bloom or blossom, is the reproductive structure found in flowering plants (plants of the division Angiospermae). The biological function of a flower is to facilitate reproduction, usually by providing a mechanism for the union of sperm with eggs. Flowers may facilitate outcrossing (fusion of sperm and eggs from different individuals in a population) resulting from cross-pollination or allow selfing (fusion of sperm and egg from the same flower) when self-pollination occurs. There are two types of pollination: self-pollination and cross-pollination. Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant. Cross-pollination is when pollen is transferred from the anther of one flower to the stigma of another flower on a different individual of the same species. Self-pollination happens in flowers where the stamen and carpel mature at the same time, and are positione ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Honey
Honey is a sweet and viscous substance made by several bees, the best-known of which are honey bees. Honey is made and stored to nourish bee colonies. Bees produce honey by gathering and then refining the sugary secretions of plants (primarily floral nectar) or the secretions of other insects, like the honeydew of aphids. This refinement takes place both within individual bees, through regurgitation and enzymatic activity, as well as during storage in the hive, through water evaporation that concentrates the honey's sugars until it is thick and viscous. Honey bees stockpile honey in the hive. Within the hive is a structure made from wax called honeycomb. The honeycomb is made up of hundreds or thousands of hexagonal cells, into which the bees regurgitate honey for storage. Other honey-producing species of bee store the substance in different structures, such as the pots made of wax and resin used by the stingless bee. Honey for human consumption is collected from ...

Echium
''Echium'' is a genus of approximately 70 species and several subspecies of flowering plant in the family Boraginaceae. Species of ''Echium'' are native to North Africa, mainland Europe to Central Asia, and the Macaronesian islands where the genus reaches its maximum diversity. 29 species of ''Echium'' are endemic to the Canary, Madeira, and Cape Verde archipelagos. The continental species are herbaceous, whereas all but two of the endemic species of the Macaronesian islands are woody perennial shrubs. Etymology The Latin genus name ''echium'' comes from the Greek ''echion'' referring to Echium plantagineum and itself deriving from ''echis'' "viper"; the Greek term dates to Dioscorides who noted a resemblance between the shape of the nutlets to a viper’s head. The genus Echium was published by Carl Linnaeus in 1753. Cultivation and uses Many species are used as ornamental and garden plants and may be found in suitable climates throughout the world.
