Re: I can't get sixam plants
My memory of the ins-and-outs of wild plant harvesting there are rusty, and the main wild plant harvesting I did was in Granite Falls. I think I had to make sure the plant was in season (if applicable) and at the correct point of maturity to allow for harvesting or to take a cutting. With wild plants this involves playing in that area for long enough for the plant to mature to the point that you can harvest &/or take a cutting of it. (Another thing to keep in mind is that you have to be careful when taking a cutting that you wait enough time between doing this a second time or it will kill the plant.)
There is additional information on Sixam at this link: https://www.carls-sims-4-guide.com/worlds/gettowork-sixam.php
This is a great guide to gardening, including wilt plants, cuttings and grafting, etc.: https://www.carls-sims-4-guide.com/skills/gardening/
