Sudden growth of an unknown part in a plant. Reason Not Known.

[klc243g]

This query is in reference to the image attached, wherein a long central structure can be seen in the middle of the plant. I have personally observed that at around 2 PM it wasn't present and in the evening around 5:30 PM, I was astonished to finding such a structure without any explanation. I would like to request to the community members to help me identify the structure and the reason for its sudden growth. Thanks!

What kind of plant is this? Agave? Yucca?
Regardless, it's producing a flower stalk.

I believe what you have is an agave. That growth is the flower stem or stalk. After it flowers it will either die or not bloom again for a number of years.

Thanks for the replies. Really appreciate it.

Grow, bloom, die: The curious case of Agave americana | Plants | Earth Touch News

Meet Michigan's octogenarian agave. For the first time in 80 years, it's beginning to bloom. But for this species, flowering is fatal.

The slang name for these is Century Plant. They are popular in Florida. The amazing thing about these is that you can almost watch the flower stalk grow. In a matter of days it can be taller than a house. I have never witnessed one of these plants living after blooming.

This is a variegated form of Mauritius-hemp (Furcraea foetida 'Medio-picta'), in the Agave Family (Agavaceae, or Agavoideae of Asparagaceae). The elongating structure is the plant's floral peduncle. This species is native to southern Central America and northern South America, but is grown widely for ornament and fiber, and is also naturalized in many tropical regions. The genus Furcraea is closely related to Agave, but Furcraea flowers are pendant and differently shaped from most Agave.
