My read on this is that desert, rocky terrain, and epiphytic plants find small microbiomes where they can survive. Once they have exploited those resources, once they've 'walked' looking for other spots very close by, they can't just move a couple feet away. They have to fly, and fly far, or die trying.
A hothouse in Halifax, Nova Scotia had an agave that bolted so fast they had to remove it from the building. I think it grew six inches per day, that just as interesting that a plant that big can grow that fast.
I'm positively blown away by the grapes we planted last year. We had accidentally left a hole in our bird netting and a deer got in and stripped both vines bare, as well as breaking many of the core tendrils. Swore they were going to die; within a month they had doubled their previous size, put out an entirely new and more vigorous crop of leaves, and then proceeded to produce two entire bunches of Riesling. (on year ~1.5 after planting).
As someone who kills most everything I put in the ground, so much love for the robustness of grapes; they probably put out at least a few inches of vine a day even at this point.
You really should go check out a vineyard in November/December. It's absolutely shocking how much of the growth is removed - virtually 100% of it - each year. And every year in late winter/early spring the first bud breaks, and for the next several month you can't even fathom how much they grow.
Fascinating - I live in NM and have seen both the yucca blossoms but also what appear to be the same thing as those agave spears. I had assumed they were all yucca around these parts as the plants that give off the tall spear blossoms are smaller than the agave I’ve seen in Mexico and SoCal, but I’m thinking they are just another agave variety.
The Agave must build up a large store of starch over many years to be able to grow this reproductive organ so quickly. It is this large starchy part of the plant that is harvested in the mature Agave plant to make tequila.
The monocots are a huge clade, making up 23% of all angiosperm (flowering plant) species. Asparagus and agave are related to each other just as much as they are to grasses and bananas. It's like saying snakes and humans are related to each other. Usually when we say two plants are related we mean something like they're in the same family.
