When I see a picture of Gold Hahnii like that, the first thing I do is look where they are growing at. Like said, up north is very hard to winter over. Sans can live well down into the 50's. Some say even the 40's (degree Fahrenheit). Sans. trifasciata hahnii 'Gold Hahnii' seems to never leave the 60's and then only for a short time. I keep mine in a fish tank in my living room lighted 14 hrs. day. It stays in the 70's there. All other attempts I tried to keep this plant ended in failure. (root rot). Some other S. trifasciata is also demanding like similar colored but med-growing S.tri. 'Morgenstern's Futura Aurea'. Currently my favorite.
Or even harder is Sans. tri. Forescate.
Here's a picture of some of my Golden Hahnii. BTY, it's called "stacking" when they continue to keep growing up with lots of leaves.
And most are much easier to grow. Like Sansevieria kirkii Pulchra 'Coppertone'
Or the Sansevieria guineensis Metallica 'Tenzan'. Very undemanding.
And my regular tall growing Sans. trifasciata were reaching 50 inches. Had to use tomato cages to keep them looking good with out some leaves falling over.
Come spring when I take them out. We'll see what extras I can part with.
