I got some in a bouquet back in November 2020, and while everything else is long dead, the ruscus is still going strong in a vase of water that I refresh very rarely.
I also was curious if it could be propagated and googled a little to see what I could find. Since I'm rarely successful at it I didn't bother and instead kept it in water on a shelf. Your question inspired to me to actually look at it and this is what the growth on one if the leaves looks like now.
