Thread-leaf Agave in Fall 2020--Emerging Stalk and Buds

Also view "Thread-leaf Agave in Fall 2020--Blooms, Bees, and Beyond" video (13:30 runtime).

Early October 2020, I spotted an agave with an emerging stalk (about 7' high). Also, the ballish shape of the leaves ("rosette") caught my eye. I've seen numerous agaves sprout stalks in spring. By the time I identified the plant as a thread-leaf agave, I found info about the stalk emergence and timing:

From "Thread-leaf Agave
Agave filifera subsp. schidigera"

At maturity, in late summer, it produces a flower stalk that reaches eight feet or more with attractive purple blossoms that occur on the upper part of the stalk.

From "Agave Filifera Care: Growing Thread-Edge Agave Plants"

When mature, Filifera will bloom by sending up a 6’ to 8’ foot long flower spike from the center of a rosette. There is no set time of year for this event to occur.

Incidentally, for excellent images and descriptions, visit "Agave filifera (Thread Leaf Agave)" and "Plant Highlight: Agave filifera".

I visited the plant several times during October and November, taking pix and recording videos. In readying for images and video clips, I decided to create two videos. This video (with October images) features the start of the emerging stalk and progressively denser bud clusters. (I even captured a gathering of deer.)

First Impression (Incorrect), Queen Victoria Agave

Initially, i thought the agave was a Queen Victoria agave. The base was ball-shaped, with short, arced leaves such the pic at "Queen Victoria Agave". In 2012, I had spotted a newly planted one with a small plastic ID stake. So cute that I took couple of pix and made a composite. 

I noticed when poring through online images that the somewhat spherical base ("rosette") had thread-like fibers, and that the leaves were pointy like yucca leaves. It turns out that my subject plant is a thread-leaf agave, aka filifera.

November Observations of Thread-leaf Agave

The other video (with November images) features blooms, bees, and post-bees, with noticing the increasing leftward lean of the stalk. (The closing section shows comparisons of the lean over time.) I recently strolled to the site and saw bare ground, as though the plant was never there.

The article WRT November 2020 agave images contrasts the filifera to a close relative, the schidigera, both part of the Asparagaceae family.
