I was just thinking about how triffids actually reproduce. They’re supposed to be animate plants, yes? So how are they born? They seem intelligent enough to be aware of situations collectively, and they already cultivate their own groves; why not farm their own offspring?
I don’t know if this would be its own special biome, like fungal towers and fungal bloom, but in my head I see a big field of carefully sewn fields lined with big twitching infantile triffid stems in various stages of development. As plants it makes sense that, in the very beginning, they’d be anchored to the earth and extracting nutrients straight out of the ground, or maybe connected to some kind of feeding system connected via roots that, very far away, connect back to the triffid heart. They need to build up their bodies first, and it’s more efficient to save energy by anchoring one’s self to the earth and sucking up whatever they need however they need it, whether by photosynthesis, direct feeding, ect.
Once they’re developed enough to defend themselves or have grown the parts they need to create energy more efficiently, all their fluid bladders are filled, ect, then they either uproot themselves or some kind of caretaker unit shuffles over and does it for them. At that point they’re either full-grown triffids or triffid sprouts (that later grows into an actual triffid).
This can either be above ground or below it, branching off of the tunnels and such that come off of the triffid heart. To me it makes sense to have a special field to do this, since they’re more like crop warriors than anything precious and important to them and grown en masse. There could also be special places specifically designated to grow their triffid queens, and are much more heavily defended due to the important role that the queens play in cultivating and expanding the groves.
It would also be nice to see a bit of variety in the triffid faction this way. Currently I think there’s only the generic grove, which means roaming queens carving paths of destruction across the landscape. This would spice up the environment a bit and also give us access to triffids without having to constantly check to ensure that the queens aren’t roaming everywhere and destroying absolutely everything, or heading somewhere they shouldn’t.
I’m also thinking there would be giant nutrient ‘stomachs’ of some variety to feed growing and perhaps adult triffids, but those could just be part of the nursery.
Just some ideas thrown out there.
