Best Fast-Growing Indoor Plants: 15 Ranked (2026)

Polka Dot PlantSpider PlantBoston Fern
Short answer

The best fast-growing indoor plants are Polka Dot Plant, Spider Plant, Boston Fern. Sodate ranked 19 qualifying plants from a database of 208 profiles on a published 100-point rubric weighted to growth speed (40), care difficulty (25), pet safety (20) and cost (15). Polka Dot Plant scores 100/100, the highest in this group.

TL;DR

Polka Dot Plant, Spider Plant, Boston Fern lead this ranking of fast-growing indoor plants. Entry requires scored from the growth rate stated in each profile, with full marks for plants described as fast with a figure attached. 4 of the 15 listed are non-toxic to cats and dogs. Every score is computed from the same four measures, growth speed, care difficulty, pet safety and cost, and the rubric is published below so you can recompute any ranking yourself.

Why trust this list

Fast growth is the most underrated quality for a first plant, because visible progress is what keeps people caring for it. It cuts both ways though: a fast plant in the wrong spot gets leggy fast, and a fast climber needs support and pruning within a season. Scores come from the growth rate stated in each profile, and the fastest plants here are also the ones you will be pruning. Everything here is an indoor plant profiled on this site, which means light is the binding constraint rather than temperature or rainfall. Check the light row on any plant before buying it, because indoors the difference between a north and a south window is larger than the difference between most of the plants on this list.

How we scored these

Every plant is scored out of 100 on four measures, each pulled directly from its care profile. No score is assigned by hand, so the ranking can be reproduced from the data:

40
Growth speed: scored from the growth rate stated in each profile, with full marks for plants described as fast with a figure attached
25
Care difficulty. Forgiveness of missed waterings and inconsistent conditions
20
Pet safety. Non-toxic to cats and dogs scores full marks
15
Cost: entry price for a typical starter plant in the US

Ties are broken alphabetically. Prices are researched typical retail ranges, not live quotes. Check each plant's profile for the regional breakdown. 19 plants in the directory met the entry bar; the top 15 are listed here.

Stop guessing whether that corner is bright enough

Sodate measures the actual light where your plant sits and builds its watering schedule from that reading and your season, not a fixed interval. Currently in development.

See Sodate: coming soon

What to check before buying

  • Ask where the plant was grown. Greenhouse-grown stock looks perfect for weeks on stored energy before it shows dim-room stress
  • Check leaf spacing on the stem: wide gaps mean it was already stretching for light before you bought it
  • Choose plain-green over variegated for genuinely dim spots. Variegated leaves have less chlorophyll and need more light
  • Inspect leaf undersides and stem joints for pests, which spread faster on plants stressed by low light
  • Confirm pet toxicity yourself if you have cats or dogs, rather than relying on shelf labels

Red flags to walk away from

  • Fast growth promised without a light requirement attached. Nearly every fast plant is only fast in bright light.
  • Vining plants sold without a support. They grow quickly and then sprawl, which is a pruning commitment, not a decor choice.
  • 'Grows quickly' used to sell a plant that will outgrow the room. Check the mature size before the growth rate.
  • Plants photographed in bright greenhouse conditions and sold for dim rooms. Ask how long the plant was grown under that light.

Best time to buy

Buy in early spring. You get the entire growing season ahead of you, the plant establishes before winter, and you see the growth these plants are bought for rather than waiting months for it to start.

Frequently asked questions

Why has my fast-growing plant stopped growing?

Almost always light, and secondarily season. Most of these plants slow or stop from late autumn to early spring regardless of care, and a plant described as fast will be slow in a dim corner.

Do fast-growing plants need more fertiliser?

More than slow ones, yes, but only during active growth. Feeding a dormant plant in winter does nothing useful and salt build-up in the soil can burn the roots.

Will a fast grower outgrow my space?

Several here will. Check the mature size row on each profile. Fast plus large is a pruning commitment; fast plus compact is the combination most people actually want.

How do I judge the light in my room?

Look at the shadow cast on a bright day. A sharp-edged shadow means direct sun, a soft but definite shadow means bright indirect, and a barely visible shadow means low light.

Should I rotate my indoor plants?

Yes, a quarter turn every week or two. Indoor light is directional in a way outdoor light is not, and rotating prevents the lopsided growth that follows.

Limitations of this ranking

Stated plainly, so you can judge how much weight to give it:

  • No physical testing. Nothing here was grown, timed or measured by us. Every score is computed from the structured care data on this site, which is compiled from the botanical and horticultural sources listed below.
  • Prices are researched ranges, not live quotes. They are typical retail for a standard starter size and will drift. Each plant profile carries the regional breakdown for five countries.
  • Scores are relative to this directory, which holds 208 profiles. A plant absent from the directory cannot appear here, so this is not a claim about every plant in existence.
  • Care data is species-level. Your light, your water and your home will move any of these plants up or down more than the gap between adjacent ranks.
  • No individual expert reviewer is named. These pages are compiled and edited in-house against a published rubric. Where a claim matters, the source is cited below rather than attributed to an unnamed authority.
