Re: 'Cupped Trap'
I've been growing this clone for nearly 3.5 years and don't find it any more vigorous than any of the dozens of "typicals" I have. Indeed I find that many of it's annoying habits make it less likely to thrive than your average typical (how's that for redundancy). I've had maybe five or six die on me since I found the one I started out with in a local Home Depot. Fortunately the first thing I did was cut the flower stalk on it and send it to a friend to propagate in tissue culture. Thus I had backups available.
The first year out of tissue culture it grows splendidly (but what flytraps doesn't).
I find it to be an attractive looking mutation. Yes, the traps are fully functional and are capable of catching prey on their own. The traps are sometimes slower to close than "normal" form traps but they still catch prey.
Under lights or very strong sunlight they color up nicely, but then again so do many flytraps.
They flower constantly whether you clip the flowers early or not. 8 flower stalks over the entire growing period is the record for me so far.
Worse than that this plant has a tendency to divide when they flower. While you may think this is a good thing the result is that the rosettes never get much bigger than two or three inches across. And the survival rate of the divisions are poor.
Also the flower stalks are relatively thin. You are more likely to get strikes from thicker flower stalk cutting for obvious reasons.
They go through trapless phases. Either tiny traps or just a "tendril" or nub instead of a trap. Usually this happens for the first month or two after coming out of dormancy or while flowering (clipped or not) but can happen at any time. I've had two plants in the same pot (flower self-divisions from the previous year) one without traps the entire growing season
