You can acquire a variety of gold items in Animal Crossing: New Horizons. They are lovely items to have in your collection, but you can acquire golden flowers, too. Receiving them works a bit differently than adding a golden item to your toolkit.
To acquire a golden flower, you first need to make a black flower of that species. For example, if you have roses, you need to place two red roses next to each other with a space between them. If you water those flowers, over time, a black rose will spawn between them. The black roses then need to be dried out, so try your best to forget watering them and let nature do its thing.
Once they dry out, you need to give them water using a golden watering can. We believe the golden water can is provided to you when you need to maintain a perfect town for 15 days and then speak to Isabelle. After you water the dried black roses with the golden can, the gold flowers should come shortly after. For other flowers, the process could vary because the different color combinations also change for each type of flower in Animal Crossing.
If you get golden flowers through other means, we’ll make sure to update this guide to reflect this information. For now, we know golden roses come from dried black ones after you water them with a golden watering can. You can try to obtain different hybrid combinations by placing the flowers next to each in your town to see what they become.
