After hearing for years and years about Dracaena fragrans blooms and how drippy / strongly-scented / etc. they are, I have finally experienced it for myself for the first time. It's true: Dracaena 'Indonesian Tracker' and D. fragrans have both bloomed for the first time, within a few months of one another.
The process is surprisingly quick. I noticed the developing flowers for the first time on 7 November,
a couple flowers opened on 25 November, and then a whole bunch of them opened on the evening of 26 November (U.S. Thanksgiving). The blooms are difficult to photograph, since they're only open at night, so I only managed one good picture on one of the two spikes, but it's enough to get the idea.
What I was most interested in was the fragrance. I've heard people say that the smell was so strong, it filled their whole house, and they had to cut the blooms off because they just couldn't stand to live with the plant while it was blooming. This turns out to be an exaggeration. Or maybe we just have insensitive noses. Either way, the husband and I agree that it's pleasant, and although it does carry quite a ways into the house from the plant room, the odor isn't overpowering or incompatible with human habitation or anything like that, even with two spikes in bloom at once. I can't even smell it in the basement. The husband likened it to the smell from the Murraya paniculata, both in character and intensity, which sounds right to me. I mean, if I tried really hard and had both of them present to compare directly, maybe I could tell a difference between the two, but if I didn't know the Dracaena was responsible, I would completely believe someone who told me the odor was from the Murraya.
The smell starts up at about 4 PM, when it smells very much like cut grass, with a hint of lilacs. That gets stronger and stronger until about 6:45 PM, when it abruptly switches to the heavy Murraya smell. I have no idea how long the smell will last; individual flowers don't seem to last very long, but there are so many of them. (I'm writing this on 29 November; the show may be completely over by the time you read this. I don't know.)
I've also read a lot of complaints about nectar dripping from the flowers and what a pain it is to deal with; that hasn't really been my experience either. There's nectar, yes. And it does drip. It just doesn't drip in the quantities I've seen described, and as far as I can tell, what little nectar has dripped has mostly landed on the plant itself, or other plants. Which isn't ideal, of course, but it isn't really a problem. Maybe it gets worse later. In any case, the plant room floor is concrete, so even if it does get thoroughly coated in Dracaena nectar, cleanup should be pretty easy. Overall the whole thing has been a lot less of a catastrophe than I was expecting.
