Orchids are fabulous houseplants that require very little watering. In college, I had an orchid in my room, and I only had to put a little water in the pot once a week. Orchids are elegant, so they might be a flower of choice if you have a more minimalist aesthetic to your room. They, of course, also come in a beautiful range of pastel shades and have gorgeous blossoms. They're a fabulous houseplant to have, and they definitely bring floral oasis vibes. Just remember: you might have to water them a little more when the weather gets dry.
