Espostoais a genus of 16 species of cacti known from the Andes of southernEcuadorandPeru . They usually turn from 2625 to 8200 animal foot ( 800 to 2500 m ) above ocean level .
The generic name abide by Nicolas E. Esposto , a famed plant scientist from Lima .
Espostoasare columnar cacti that mostly branch at the base to form a series of stems reminiscent of a big city skyline . The most notable feature of speech ofEspostoas is a bearing in most metal money of dense white hair , which quite dramatically cover the stem turn giving them a soft blurry appearance . However , this is just an illusion , as underneath the soft hair are legion knifelike spines arrange on many lowly ribs that circulate the columns . In some species , the master central spine extends well past the hair making their threatening presence obvious .

Another trait ofEspostoas seen in mature radical is the flower - bear lateral cephalium , an area along the stems that produce especially dense wool and/or bristles from which the flowers look . These structures are brown , greyish , or white and look like something was smear along one side of the stem . Flowers are cup or bell - forge and typically 1 to 2 inches ( 2.5 to 5 cm ) in diam . They are normally whitened or rarely reddish and nocturnal . Fruits are edible , fresh , and red-hot .
Several species ofEspostoaare especially pop in finish due to their fuzzy lily-white hairy appearance . big commercial raiser sell the plant as up to 12 inches ( 30 atomic number 96 ) longsighted stems . However , these plants do not grow nearly as smartly in pots as in the soil . Instead , plants chop-chop fill the pots , becoming sens - bind , and then growth slows to a crawl . As a result , these industrial plant rarely , if ever , reach adulthood , meaning they do not produce cephalium and , later on , do not blossom . On the other hand , those in warm climates that can plant the specie directly in the ground may indeed have plants that form a decent grouping of stems that will eventually bloom .
Like most cacti , Espostoas require a gay location andwell - drain dirt . In summer , they appreciate fertiliser and bedwetter precondition . In winter , they need eternal sleep , but the temperature must not drop below 54 ° F ( 12 ° C ) .
They are apprise for their decorative qualities due to their white fleece .
