Large dew flowers from Into the Future

I did place the spawners in Riverview but they never produced any Dew Flowers. I think I may have put them in other worlds as well with no luck. I wondered if my sim visited the utopian future if they might start spawning. I sent him to the normal future and they never spawned any flowers. I might try using NRAAS Traveller mod to see if they spawn when using the Force Spawners menu choice of Traveller mod. I don't think it'll work though.

EDIT: I added the mod @wendyyi1 mentioned and it adds the flowers to BuyDebug and they cost 5,000 simoleans each. I added some of the flowers to my sim's lot and they are now in their garden.

I now need to check the shape of the flowers and if there is any variety in how they are growing.
