Many of the houseplants that reproduce on their own reproduce with spores. Spores look like little block dots on the underside of many types of houseplants. On other houseplants, they are hard, if not impossible, to see. The spores grow into male and female gametes. When a male and a female gamete get together, they then continue to grow to form an adult plant.
Succulents are one of the families of plants that reproduce with spores instead of seeds. Aloe is one of the most commonly known plants of the succulent family and is a popular houseplant. Keep succulents out of direct sunlight. They like filtered light from the afternoon sun, such as from a sheer that hangs in your window. Succulents enjoy hot weather, and this is when you will notice new shoots appearing. Do not over water succulents. They use their thick stems and leaves to store a lot of extra water.
The spiderworts are another family of houseplants that reproduce on their own. These include the traditional spider plant and the wandering Jew. The spider plant has light to medium green leaves, while the wandering Jew has dark green leaves with purple running through. Both plants enjoy being in bright sunlight, although not direct sunlight. Over time, you will notice the plant growing larger outgrowing the pot. Separate the plant and repot some of it to have a completely new plant. Fertilize twice during the month after separating and repotting to give it the necessary nutrients it needs to grow properly.
Ferns are leafy green plants that you can bring into your home and will reproduce on their own. Ferns also regrow from spores. During certain times of the year, you will notice the underside of the fronds have bumps. These bumps are the spores. The spores will eventually fall off, growing new plants. Good types of ferns to grow indoors include Boston, Button and strawberry.
