Den superbum (anosmum) var. alba
This is one of my most favorite dens. I got it from Hausermann's maybe 5 or 6 years ago as a blooming baby with 3" canes.
Super easy for me. Summered outdoors where it's watered and fertilized heavily while growing. In the fall, when it is brought back indoors to a southeast window, I start to cut the water back, and when the leaves start to drop, I cut most of the water off. In the spring, when the buds and new growth start developing, I begin watering and fertilizing again.
I've not detected a scent yet (I probably haven't been home at the right time), but it usually has a very pleasing sweet scent. I'll post a better picture when it is fully in bloom. The close-ups where blurry so I didn't post them.
