This cactus about five meters tall blossoms once a year, if I have been noticing correctly, I can't be certain on that. But when it does blossoms you are sure to notice it, or lets say I am definitely sure to notice it as a nature lover.
It is currently in that blooming period and it just gives it a different kind of beauty unlike the all green it normally is. I wish the sky above was bright to give a nicer background look but its been grey skies for about three days now.
It is time for big cactus to blossom.
