The caudiciforms

Ibervillea lindheimeri, 1 year + 9 months
Trochomeria macrocarpa, 1 year + 9 months
Dioscorea elephantipes, 1 year + 7 months
All of my outdoor caudiciforms have now lost all of their leaves and gone dormant. I really want to keep them outside over winter and they should be able to handle it, but in the back of my mind I just know I’m going to bring them indoors when it gets colder.
