Yucca baccata is a nice medium sized yucca that is very cold hardy, however I did have one freeze to the ground once but came back from the roots and has never done so sense.
They can take lower ground in the winter than most of my other desert yuccas and can even be trimmed to show short trunks (some).
This my trimmed Y.baccata, it is 38inches high and has 4 different crowns/trunks.
This one is trimmed up mainly because it is so close to the path that it needs maintenance.
This one my get a good trimming as well, nice thick trunk.
This one was split from the above, when moved. I can tell you this they way a ton!
Every baccata I get is different from the others.
I know of least 5 different forms of baccata. some are trunk less, while other can be over 5' tall.
And this one for no reason has done very little, I should stop and say hi to it more often.
