I was driving on CR 200 just north of Liberty Hill a few days ago and spied some big blooms at a driveway entrance. I knew nothing should be blooming of that magnitude now so I just had to turn around and check it out. It turned out to be a rather artsy way of dealing with Century Plant thorns close to where the kids wait for the school bus. I've never cared for the way some people plant an Agave or a Yucca and then lop off the thorns so no one will get stuck. It just makes the plant look bad. It seems they should have planted it elsewhere.
These looked like they should have been on my Sisters street in south Austin as they just have that south Austin flair to them. Very innovative.
