It went from non existent to taller then the 2 story building in a month. A plant app I used identified it as Agave Americana. But I can't find any literature describing this accelerated growth.
Any ideas?
Edit: this is in Los Angeles California.

Wrt. corpse flower. 25 years ago i come one morning to work, a bit late as usual - i'm the IT - and the smell in my office is beyond description and it is emanated by that large phallic looking flower. The combination of look and smell is stunning, and my officemate (a very polite mid-age school teacher kind of woman) has an extremely strange expression on her face - on one side it is of a great proud - after all her "child", that flower she tended to for so long has finally bloomed in such a grandiose spectacular manner - on the other side she has already spent some time in the office and the tears in her eyes weren't just the tears of proud - it was just very hard to breath. I took the flower out into the hallway - we had that long hallway with offices' doors opening into it - and placed it toward one end of the hallway. 5 minutes later i hear the noise of tremendous excitement mixed with disgust - the people from the office closest to the flower got bothered by smell and walked out to check it out. Once they took their emotions under control they moved the flower to another end of the hallway. In few minutes people from the offices there got bothered by the smell ... That chess play with flower went for some time until finally somebody moved the flower into the stairway where during the day some people from the other floor also came to check out the source of the smell.

It's their death bloom.
Anecdata. Your plant is also a close relative from Agave tequilana, the main ingredient of Tequila. The genus is easy to culture and lots of species are heavily used in dry gardens.
