Thread-leaf Agave in Fall 2020--Blooms, Bees, and Beyond

Also view "Thread-leaf Agave in Fall 2020--Emerging Stalk and Buds" video (12:19 runtime).

My observations of this thread-leaf agave with emerging stalk was October and November 2020. The October video's images are from October 7 through 29, ending with progressively denser bud clusters. For more info about this time period (emerging stalk, buds, similarity to Queen Victoria agave), read "Thread-leaf Agave in Fall 2020--Emerging Stalk and Buds".

My video's images are from November 3 through 20, which include blooms and bees, and also noting the increasing leftward lean of the stalk. (The final segment compares the lean over time.) I recently strolled to the area and saw bare ground, as though the plant was never there.

Filifera vs. Schidigera Agaves, Close Relatives

In researching my subject plant, I looked at several websites for differences between filifera and schidigera. Best help came from some sites that included descriptions and pix of both agaves.

"Agave Filifera Care: Growing Thread-Edge Agave Plants", mentions both filifera and schidigera being from the Asparagaceae family. Differentiation statement: "You can tell these two Agave plants apart as Agave filifera has less conspicuous and finer hairs on its leaves."

"Agave Care, Photos & Varieties" has a gallery of filifera, schidigera, and numerous additional agave types.

Ruth Bancroft Garden and World of Succulents each have separate webpages for filifera and schidigera, with descriptions and images.

From "Plant Highlight: Agave filifera":

  • flower coloration: "stalk, buds, stamens and pistils are all dark purple or wine-colored, the face of the flower is a pale yellow, though it too may be flushed with purple"
  • rosette-leaves: "sharp-tipped leaves are 6 to 12 inches"
  • stalk: "6 1/2 to 8 feet tall"

"Plant Highlight: Agave schidigera"

  • flower coloration: "pale yellow"
  • rosette: "2 to 2 1/2 feet across"
  • stalk: "8 to 15 feet [high]"

"Agave filifera (Thread Leaf Agave)"

  • flower coloration: "yellowish-green to purple"
  • rosette: "up to 3 feet [across]"
  • stalk: "up to 11 1/2 feet [high]"

"Agave schidigera"

  • flower coloration: "greenish-yellow"
  • rosette: "up to 2 feet [across]"
  • stalk: "up to 10 feet [high]"
