How to Choose the Right Plant

Many houseplant failures are decided at the moment of purchase. The University of California’s IPM program advises choosing plants whose growing needs, especially light and temperature, fit the place they will grow: healthy plants are less vulnerable to pests and diseases and recover faster. The Royal Horticultural Society gives the same advice from the shop floor: read the label, or look up the plant’s needs, to see whether it will be happy in the conditions you can give it before you buy.

So don’t start with “what plant do I want?” Start with “what does my space offer?” Here is a simple method.

Step 1: Assess your light (the most important factor)

The University of Illinois Extension calls light one of the most limiting factors for success with houseplants, and gives a guide to light levels by distance from a window:

Light level	North window	East or west window	South window
Low (about 75 foot-candles)	a few feet away	3-10 feet away	15-20 feet away
Medium (about 150)	directly in front	a few feet away	3-10 feet away
High or bright (about 300)	-	directly in front	up to 5 feet away
Direct (about 1,500)	-	-	directly in front

It adds that light changes through the seasons, for example when trees outside lose their leaves in winter. Some examples of its ratings: snake plant, Chinese evergreen, peace lily and parlour palm for low light; pothos, spider plant, dracaena and rubber plant for medium; jade plant and weeping fig for high light. Our light-checker tool helps you judge a spot, and our low-light plant list covers the dim corners.

Step 2: Consider temperature, humidity and draughts

Temperature. The University of Illinois says most foliage plants prefer 65-75°F (about 18-24°C) by day, with nights 5 to 10 degrees lower.
Draughts and heat. Avoid blasts of hot and cold air from windows, radiators, heating and air-conditioning vents, and take care near cold window panes (University of Illinois).
Humidity. Most homes have less than 30 percent humidity in winter, and some houseplants suffer; a humidifier, a pebble tray or grouping plants helps (University of Illinois).

Step 3: Be honest about your lifestyle

The plant has to fit you, not an idealised version of you:

Do you travel or forget to water? Choose plants that tolerate drying out. Clemson University notes that succulents with fleshy leaves and stems store water and need watering less often than plants with large or thin leaves. Our vacation guide covers longer trips.
New to plants? Start with plants that match your light, and build up from there. Our beginner mistakes guide lists what goes wrong most often.

Step 4: Account for pets and children

If you have a cat, dog or small child who might chew leaves, check each plant before you buy. Our pet-safe houseplants guide checks plants against the ASPCA’s lists of plants toxic and non-toxic to cats and dogs. Otherwise, keep toxic plants out of reach.

Step 5: Buy a healthy plant

The RHS suggests:

Buy from a reputable garden centre, where plants are generally stored and cared for properly.
Choose plants with healthy leaves and no discolouration.
Avoid plants wilting in dry compost, and especially those wilting in moist or wet compost, which can mean root damage from overwatering or root disease.
Cover the plant for the journey home, especially in winter, to protect it from cold.

The University of California adds: check new plants weekly for pests and diseases at first, and isolate any plant with a problem straight away.

Putting it together

When you spot a plant you like, run it through this checklist before buying:

Does it suit the light of the spot it will live in?
Do the spot’s temperature, draughts and humidity work for it?
Does its care match your routine?
Is it safe for your pets and children, or can you put it out of reach?
Is the plant itself healthy?

If it fails one, especially light, choose a different plant or change the plan: a different spot, a grow light or a hanging pot. Not sure where to start? The plant finder narrows it down by your conditions.

The reverse method: start with the spot

You can also shop for a spot rather than a plant: decide “I want a plant for this corner”, work out that corner’s light with the table above, then look for a plant rated for it.

Frequently asked questions

How do I know how much light a spot has?

Use the University of Illinois guide: for example, low light is a few feet from a north window, 3-10 feet from an east or west window, or 15-20 feet from a south window. A light meter gives a precise reading.

What’s the most important factor in choosing a houseplant?

Light. The University of Illinois calls it one of the most limiting factors, and the University of California advises matching plants to the light and temperature of their spot.

How do I choose a plant if I travel a lot?

Pick plants that tolerate drying out, such as succulents that store water in their leaves and stems (Clemson), and set up a water reservoir for longer trips.

What should I check in the shop?

Healthy leaves without discolouration, and no wilting in wet compost, which can mean root problems (RHS).
