Last March I cut the tops out of several Yuccas from the AR/LA Stateline. They all lived through the summer and a couple even bloomed. We got down to -6 one night and about 3 weeks below freezing. No snow to speak just cold. The tops of the yuccas fell over and became mushy. Anyone know if these will come back? I cut the tops off and now they are just sticks. Iím pretty sure they are gloriosa.
