15 Fast-Growing Houseplants To Make Your Interior Space Lush And Green

Growing houseplants can be tedious and frustrating when you nurture varieties such as Jade, Cast Iron, or ZZ plants. These slow-growers will eventually become gorgeous, mature specimens, but you'll have to wait a long time before seeing any significant changes. If you are looking for plants that will give you an instant indoor garden, you'll need to look further. There are countless plants ready to show off their vigorous growth and vibrant green foliage after they are provided with the right indoor conditions.

When you are working on building your fast-growing houseplant collection, you should keep in mind that even the plants with the quickest growth habits typically have dormant periods during the fall or winter. As explained by Salisbury Greenhouse, nearly all plants grow more quickly during their growing season in the spring and summer when they receive lots of light, water, and fertilizer. Still, you can take advantage of this cycle by choosing your favorite plants from this list that present you with abundant growth when cared for the right way.
