Americans unremarkably call their aboriginal juniper trees " cedar tree , " but true cedars belong to to the botanical genus Cedrus , and include famous tree diagram such as the cedar - of - Lebanon ( Cedrus libanii ) , deodar cedar ( Cedrus deodora ) and the Atlas cedarwood ( Cedrus atlantica ) . All are native to the western Himalayas or the Mediterranean and become tall , elegantly branching tree diagram . you’re able to see diversely aged cones on the trees any time of year .

Function

Although cedar are not blossom plant , they bring about gendered reproductive organs call " cones . " Thus , they are called " conifers . " Insects often play a role in pollinating petalous flowers , but in the case of cedar , winds facilitate the pollination of cones that results in production of seeds . Both manlike and female cones occur , but only the distaff conoid yield seeds .

Timing

Cedar trees produce their new cones in late summer on short shoot at the tips of offset . Both male and distaff cone are find on the same works but in unlike locating . Male cone are seen in profusion most heavily at arm tips in the low-spirited Sir Herbert Beerbohm Tree branches , whereas female retinal cone are found in the upper branch near the Sir Herbert Beerbohm Tree ’s tip .

Pollination

Although both young virile and female strobilus present themselves in belated summer , the male cones secrete their pollen in early fall . The numerous male cones are vertical , piston chamber - like in configuration and wanton brown , about 2 to 3 inch in duration ; they shed prosperous yellow pollen onto the malarky . The distaff cones in the upper branches are centripetal and are pollenate when pollen land on their scales . Female conoid also are erect but take care more chubby and barrel - like than male cones and are green in colouring , about 4 to 5 - inches in size .

Cone Maturation

After pollen is spill , the many male cones disintegrate and fall from the limb before winter . The female cone persevere for two to three years , slowly maturing . As the female cone eld , their colour changes from green to purplish European olive tree and finally to embrown . On a individual tree , you may see variously senior female cone base on their color .

Seed Dispersal

In the 2d twelvemonth after pollination , the female cone cell are fully brownish and ripened with seeds . The cones split open and break apart , put out seed that drop to the primer coat or are carried slightly by the wind . Each seed is browned and an abstract trilateral in shape . It is viscid with some resin and has a " wing " that allows the wind to carry it farther from the mother tree .
