Stush, those are so impressive. I grew my Golden Hahnii in my Southwest facing kitchen window last winter and then moved it outside for the summer. It's back in the kitchen window again. May get down to 58 at night inside the house, but could be colder so near the window when it gets to 15 below.
The plant on the left in the photo can in the same pot as the Golden Hahnii. I've labeled it Hahnii, but wonder if it could be Zeylanica? Photos of these 2 look alike to me. Any thoughts?
I've ordered ballyi, Hahnii Silver Streaker and KIrkii Silver Blue. Hopefully they get here unfrozen. The Silver Blue I'm a little worried about since it is coming from Thailand.
If you ever have any of the Coppertone one and are interested in any of those 3. I would love to trade or buy one from you. Thanks for sharing your knowledge. Good to hear from an expert.
