![]() ![]() ![]() Three of his drawings showed plants with flowers: two resembled the modern bedding dahlia, and one resembled the species Dahlia merckii all displayed a high degree of doubleness. Francisco Dominguez, a Hidalgo gentleman who accompanied Hernandez on part of his seven-year study, made a series of drawings to supplement the four volume report. Hernandez described two varieties of dahlias (the pinwheel-like Dahlia pinnata and the huge Dahlia imperialis) as well as other medicinal plants of New Spain. All these refer to the hollowness of the plants' stem. From Hernandez's perception of Aztec, to Spanish, through various other translations, the word is "water cane", "water pipe", "water pipe flower", "hollow stem flower" and "cane flower". The indigenous peoples variously identified the plants as "Chichipatl" ( Toltecs) and "Acocotle" or "Cocoxochitl" (Aztecs). The Aztecs used them to treat epilepsy, and employed the long hollow stem of the Dahlia imperialis for water pipes. They were used as a source of food by the indigenous peoples, and were both gathered in the wild and cultivated. Spaniards reported finding the plants growing in Mexico in 1525, but the earliest known description is by Francisco Hernández, physician to Philip II, who was ordered to visit Mexico in 1570 to study the "natural products of that country". Attempts to introduce the tubers as a food crop in Europe were unsuccessful. The tubers were grown as a food crop by the Aztecs, but this use largely died out after the Spanish Conquest. The dahlia was declared the national flower of Mexico in 1963. Like most plants that do not attract pollinating insects through scent, they are brightly colored, displaying most hues, with the exception of blue. The majority of species do not produce scented flowers. The stems are leafy, ranging in height from as low as 30 cm (12 in) to more than 1.8–2.4 m (6–8 ft). In addition, dahlias also contain many transposons-genetic pieces that move from place to place upon an allele-which contributes to their manifesting such great diversity. This great variety results from dahlias being octoploids-that is, they have eight sets of homologous chromosomes, whereas most plants have only two. Flower forms are variable, with one head per stem these can be as small as 5 cm (2 in) diameter or up to 30 cm (1 ft) ("dinner plate"). There are 49 species of this genus, with hybrids commonly grown as garden plants. A member of the Asteraceae (former name: Compositae) family of dicotyledonous plants, its relatives thus include the sunflower, daisy, chrysanthemum, and zinnia. ![]() Compare Standard and Premium Digital here.Īny changes made can be done at any time and will become effective at the end of the trial period, allowing you to retain full access for 4 weeks, even if you downgrade or cancel.Dahlia ( UK: / ˈ d eɪ l i ə/ DAY-lee-ə, US: / ˈ d æ l j ə, ˈ d ɑː l j ə, ˈ d eɪ l j ə/ DA(H)L-yə, DAYL-yə) is a genus of bushy, tuberous, herbaceous perennial plants native to Mexico and Central America.
