I finally got around to looking up what the species was like. On PlantGeek the species is described as:
A very striking plant with huge fluted and sometimes corkscrew leaves. This plant does best in a large aquarium where it will take over a large portion of the tank. It may or may not require a dormant period.They also describe it as requiring "medium high" light, which probably means my tanks will be on the low end.
The package contained seven bulbs. I put four in my main tank, two in the plant tank and one in the Macropodus tank. While the package says "guaranteed to grow in 30 days" (or they will replace the bulb(s) that fail to grow), replacement requires that you (a) retain "proof of purchase" (did I keep the receipt?) and (b) that you return the bulb. Which would mean digging through the substrate and finding it. Since each bulb is worth about 50 cents, between postage and the disturbance to the tank, it's pretty safe to say that I won't be seeking a refund (which makes me a bad consumer).
Hopefully there'll be something to report within the next 30 days.
