Hi Luna, and welcome to permies. I’m not the most active poster, but I know that I can say that you are welcome here and your voice matters.
Late fall/early winter can be a tough time in the garden, at least where I am in Pennsylvania. It is also a time for hope and planning, something I think many people are struggling with. It looks like you have a small bed and room for a few pots. I would encourage you think about more than just getting something to grow, like dill (which is lovely, keep growing that). Do certain colors make you happy? Grow a selection of plants that bloom st different times to give you that color over a longer period.
What about texture? One of my daughters (9) and spouse (considerably older) both have type 1 autism (I am borderline), and they both are extremely sensitive to touch and texture. I grow a variety of plants with soft, feathery textures that are a pleasure to touch, and they smell sweet and delightful. There are big, mature plantings of bronze fennel along the path leading to the front door, where one can brush a hand along as you walk by. They are
perennial, and also look good when they go dormant, as they hold their form (google New Perennial Movement to see how herbaceous plantings have be used ornamentally during their dormant phase).
As long as it doesn’t get too wet, you can also grow Mediterranean herbs like rosemary; I have zone jealousy of people who can grow creeping rosemary. Creeping thyme comes in a wide variety of cultivars, and the insects love it. It’s more forgiving of heavy soil than rosemary.
Could you grow vines? A climbing structure in the middle of your bed would allow you to grow beans; scarlet runner beans are arguably perennial south of zone 7, and they flower prolifically. We use them as a screen to shade our west-facing porch. They are very popular with hummingbirds. They tend not to set fruit when days are over 80 degrees, but they keep flowering. I would speculate that you would get a spring/fall/maybe even winter harvest. It’s worth an experiment.
Tomatoes may be the classic garden crop, but they are fickle, and it can be hard to find the right one for your particular situation. If you find yourself easily discouraged but want to grow tomatoes , don’t try growing a slicer or saucer tomato first; grow a cherry or grape variety. Here, an heirloom called Matt’s Wild Cherry is bulletproof, prolific, and delicious. They keep coming back via volunteers, too.
Create a log or
gardening journal , maybe on your phone, maybe using a notebook. And just one more thing; I’ve heard it said by more than one person in the know that childhood is hard, but autistic people are some of the best adults. I hope permies can be part of your tribe.
