Some time ago, I had a Venus Flytrap that sprouted a single white flower. I had no idea they could do that, and found it very interesting. Soon after, the damn thing died.
So I got another one that turned out to be two in the same pot. This time, whenever the little bastards tried to flower, I snipped the stalk as a plant care book intructed me. They have since flourished, even spawning a third new plant.
SO, if they can reproduce without the need of the flower, what the hell good is it? Do they make Venus Flytrap berries? Are there underground tubers? What?
A lot of plants reproduce vegetatively (i.e., sending runners underground, like garden weeds do) but this behavior does not preclude sexual reproduction.
What good is sex? Well, genes should be mixed up every so often to promote a more versatile population. Dispersal to new habitats is also good. The only way to do these two things is through sexual reproduction. But for the purposes of a “pet” plant it’s not necessary.
I’m not sure what kind of fruit venus fly traps make. I never thought of it before.
It is possible to grow them from seed, so like most other flowering plants, it would seem that they do produce fruit (some plants have simply lost the ability, even though they are still flowering plants botanically). I have no idea what the fruiting body would look like, but I’d guess, based on the habitat, that they might be very small, borne on the end of an erect stalk and dispersed by wind.
This site indicates they make a kind of capsule which contians the seeds.
