If you're someone who doesn't love the idea of bringing soil indoors but still wants the lush aesthetic of houseplants, there is a solution for you. You can easily grow some of your favorite blooms using non-soil alternatives, like water, clay pebbles, or peat moss. Another soil-free option is to grow epiphytes like air plants, or tillandsias. These plants don't require soil and mainly receive nutrients through air and water. You can still grow some classic flowers, like tulips, daffodils, and hyacinths.
