While we were in St. George for the reunion my Grandpa pointed out this plant.
It's called a Centurey Cactus, because like you guessed it only blooms once ever 100 years.
The other 99 years it just looks like a very straight rod growing out of the ground.
It was beautiful and unlike any other plant/flower I've ever seen.
So, in my lifetime this plant will never look like this again.
That just seems so crazy to me.
I felt fortunately to get to see one in bloom.
If you plan on being in St. George in 100 years and want to check this one out let me know and I'll tell you where to go looking.
