Hi Rob, this Yucca is Y. elata. It's starting to get tall. Probably over 6' tall now. The dark spots on Yucca leaves is some sort of fungus. I have a spray for it but don't use it since it always happens in my climate on certain Yuccas. Yucca gloriosa variegata is the WORST. I have a Yucca filata which is very bad too. The best thing to do is plant Yuccas which are more resistant to it. |
