There is nothing better than a giant houseplant, in our opinion. Plants, of course, will grow and grow if given enough space. And we absolutely love them.
From this giant Boston fern we got in for BBC Gardeners World Live to this huge Dracaena Draco that we sold on behalf of one our private growers, we always find a home for them.
Large plants are easier to keep because they're already a lot more established, so can tolerate a lot more neglect! And there is a lot more soil in the pot, means you can fully drench it and the plant will take a lot longer to dry out. Plus, you get a lot more foliage for your money!
