This is a Century Plant also known as the Agave Americana. It is not the kind you get Tequila from , that is the Blue Agave.
It has a flower spike that bursts forth around every 10 years,shoots 20-30 feet tall and then falls. The plant dies over the next couple of years and – to start the entire process once again.
These photos taken a week apart.
The skies here are clear early,growing hot and humid by mid-day with thunder clouds over the mountains which make the valley below broil.
This too shall pass, was it just last week I was so happy it was still cool and overcast!!??!
