8 Fast-Growing Houseplants You Can Watch Change Week by Week

Some plants grow so slowly you barely notice. These 8 fast growers reward you with visible change week by week — ideal for impatient plant lovers.

One of the most satisfying things about growing plants is watching them change. These eight species grow fast enough that you'll notice new leaves, longer vines, or thicker clumps within weeks.

8 Fast-Growing Indoor Plants

• Pothos — can grow 30+ cm per month in ideal conditions; trails quickly from shelves.
• Tradescantia — root cuttings in water within days; one of the fastest propagators.
• Mint — spreads aggressively in spring and summer; fills a pot within a month.
• Spider Plant — actively produces baby plantlets (spiderettes) that create a cascading effect.
• Basil — seed to harvest in 4–6 weeks; one of the most instantly rewarding plants to grow.
• Lettuce — ready to harvest from containers in just 3–4 weeks.
• Philodendron — produces new leaves weekly during the growing season.
• Lucky Bamboo — grows in water alone; one of the fastest hydroponic options.

How to Maximize Growth Rate

• Maximize light — more light equals faster growth for almost every species.
• Fertilize in spring and summer — monthly liquid fertilizer makes a significant difference.
• Use the right pot size — roots need room to expand for the plant to grow upward.
• Water consistently — don't let fast-growing plants dry out completely between waterings.

Put Pothos cuttings in a clear glass of water — you can watch the roots grow in real time. A great natural education activity for children.
