I know I have a wild solanaceous plant we call papolo berry. It can be used for dye and the ripe berries are edible.

I have a lot of bindweed, wild bittermelon, nut sedge, milkweed, California grass, Fukien tea, asparagus fern, syngoniums have gone wild, sanseveria, pigweed, escaped black bamboo, guava, spurge, desert honeysuckle that invaded from the neighbor's yard, African tulip and allspice also from the neighbor's yard. Grass is a weed in my brick patio and around the garden edges. I used to have Emerald zoysia in the back yard. I have some volunteer tomatoes, begonias, clover, wild amaranth,beard grass, kylinga, sleeping grass, swollen fingergrass. The St. Augustine grass lawn is nearly if not dead, but the grass is invading my borders. And these are just the weeds I can identify.
My rambler rose can travel quite a distance (15 feet) and it can be hard to reign that one in too, especially since it is a thorny proposition. The same is true of the bougainvillea and night blooming cereus that likes to go over the wall. It is hard keeping them at bay. If it rains they can really grow faster than I can keep up with them. the Kai Choy cabbages are all volunteers from last year. I planted the mustard cabbage to control nematodes and they have come back. So did the nasturtiums. I have a couple of weedy shrubs, I have no idea what they are. All I know is that they are really hard to kill.
Almost all the vegetation are weeds. The garden is surrounded by potted plants so there is also pineaple, a couple of fruit from the calamondin, green onions, and taro that are in the pots. There are more things there but I can't make them all out.
I capped off the sprinkler system in the back yard a while ago since there was more weeds than grass and the potted plants started taking up more and more space, so that only the weedy path remained. My back yard stays wet anyway since I have to water those plants almost every day.
I have weeded the garden multiple times, after a while I just plant right through them, otherwise, I will never get anything out of it. I pull the weeds I can get to, the plants compete with the weeds and if they are big enough, close enough and get taller than the weeds, they actually act as a living mulch. I interplant whereever I find space between plants and I don't really plant in rows. I do have to make sure things get along. I found out that kale and strawberries are not happy together and cabbage and okra were not fans either. I try to put the smaller short-lived plants in the garden and the bigger longer and longer lived plants in pots. There are some exceptions the aloe was supposed to be temporary, and the Jamaican oregano was in a pot, it is now through the pot and into the ground. I have some garlic chives in the garden as well but it is the most well behaved of the bunch. I have a few holes in the Brussel's sprouts but other than that, most things are doing o.k. and I have not done anything except put out a lot of slug bait.
Happy gardening in Hawaii. Gardens are where people grow.
