Every list answers this with the same four names, and the reasons are always about leaves: rigid, thick, waxy. None of them is a number and none of them mentions the cold. So here is one spot instead, with both halves of a draught held at once: a north-facing sill, the plant against the glass, 18 °C, air moving strongly past it from a gap in the frame.
Worth a try
It can work here with a little care.
Just the right amount of light
A little cool, but workable
Humidity suits it
Airflow isn't quite ideal
| The plant on that sill | What the warmth is doing | What the airflow is doing | Verdict |
|---|---|---|---|
| Cast iron plant | Comfortable temperature | Airflow isn't quite ideal | Great fit, 94/100 |
| Bird's nest snake plant | A little cool, but workable | Airflow isn't quite ideal | Worth a try, 67/100 |
| ZZ plant | A little cool, but workable | Airflow isn't quite ideal | Worth a try, 66/100 |
| Jade | A little cool, but workable | Airflow isn't quite ideal | Not the best fit right now, 44/100 |
| Parlor palm | Comfortable temperature | Airflow doesn't suit it | Worth a try, 67/100 |
| Peace lily | A little cool, but workable | Airflow doesn't suit it | Worth a try, 63/100 |
| Bambino fiddle leaf fig | A little cool, but workable | Airflow doesn't suit it | Worth a try, 63/100 |
The draught separates none of them
Cast iron, snake plant, ZZ and jade return the same airflow phrase, word for word. All four prefer medium airflow, and a preference in the middle of the scale is never more than one step from any spot, however still or however breezy:
| How the air moves there | Verdict |
|---|---|
| Still air | Worth a try, 67/100 |
| Light air | Great fit, 94/100 |
| Medium air | Great fit, 100/100 |
| Strong air | Great fit, 94/100 |
Only dead-still air costs it anything. The temperature column is where they stop agreeing: floors of 7 °C for the cast iron plant, 10 °C for the jade, 15 °C for this snake plant and 16 °C for the ZZ. Nine degrees, on a list whose whole subject is cold air, and the ZZ that gets praised for handling temperature swings has the highest floor of the four.
Above 16 °C the list has nothing to sort
| Hold the room at | Left outside | Inside its band |
|---|---|---|
| 7 °C | Bird's Nest Snake Plant, ZZ plant, Sunset Jade and 3 others | 1 of 7 |
| 10 °C | Bird's Nest Snake Plant, ZZ plant, Parlor palm and 2 others | 2 of 7 |
| 12 °C | Bird's Nest Snake Plant, ZZ plant, Parlor palm and 2 others | 2 of 7 |
| 15 °C | ZZ plant, Peace lily, Bambino Fiddle Leaf Fig | 4 of 7 |
| 16 °C | None | 7 of 7 |
| 18 °C | None | 7 of 7 |
| 21 °C | None | 7 of 7 |
Every one of them is inside its band at 16 °C and above, so a warm room with a draught in it is not a plant-selection problem at all. The warm end of this same column turns out to be even quieter. Below that line the ordering appears fast. Same sill, same moving air, six degrees colder:
| The same seven, six degrees colder | What the warmth is doing | What the airflow is doing | Verdict |
|---|---|---|---|
| Cast iron plant | A little cool, but workable | Airflow isn't quite ideal | Worth a try, 66/100 |
| Bird's nest snake plant | Too cold here | Airflow isn't quite ideal | Not the best fit right now, 44/100 |
| ZZ plant | Too cold here | Airflow isn't quite ideal | Not the best fit right now, 44/100 |
| Jade | A little cool, but workable | Airflow isn't quite ideal | Not the best fit right now, 42/100 |
| Parlor palm | Too cold here | Airflow doesn't suit it | Not the best fit right now, 44/100 |
| Peace lily | Too cold here | Airflow doesn't suit it | Not the best fit right now, 42/100 |
| Bambino fiddle leaf fig | Too cold here | Airflow doesn't suit it | Not the best fit right now, 41/100 |
One plant left, on the strength of a floor nine degrees below the ZZ’s. Its own floor is 7 °C, so even it has an end that an unheated hallway can find.
The light decides who is in
Everything so far holds one window fixed. Change it, keep the cold and the draught exactly as they were, and the order does not shift so much as invert. The dim version of the spot, then the bright one:
| On a cold, drafty north sill | What the light is doing | What the warmth is doing | Verdict |
|---|---|---|---|
| Cast iron plant | Just the right amount of light | A little cool, but workable | Worth a try, 66/100 |
| Ocean spider plant | Just the right amount of light | A little cool, but workable | Worth a try, 65/100 |
| Aloe vera | Too dim here | A little cool, but workable | Not the best fit right now, 42/100 |
| Jade | Too dim here | A little cool, but workable | Not the best fit right now, 42/100 |
| Echeveria | Too dim here | A little cool, but workable | Not the best fit right now, 42/100 |
| ZZ plant | Just the right amount of light | Too cold here | Not the best fit right now, 44/100 |
| Peace lily | Just the right amount of light | Too cold here | Not the best fit right now, 42/100 |
| On a cold, drafty south sill | What the light is doing | What the warmth is doing | Verdict |
|---|---|---|---|
| Cast iron plant | Too bright here | A little cool, but workable | Not the best fit right now, 43/100 |
| Ocean spider plant | A bit bright, but workable | A little cool, but workable | Worth a try, 64/100 |
| Aloe vera | A little dim, but workable | A little cool, but workable | Worth a try, 64/100 |
| Jade | A little dim, but workable | A little cool, but workable | Worth a try, 64/100 |
| Echeveria | A little dim, but workable | A little cool, but workable | Worth a try, 64/100 |
| ZZ plant | A bit bright, but workable | Too cold here | Not the best fit right now, 42/100 |
| Peace lily | Too bright here | Too cold here | Not the best fit right now, 21/100 |
The cast iron plant, sole survivor of the cold table, is the worst row at the bright window. Aloe, jade and echeveria do the reverse: too dim against the north glass at 3,640 lux, workable at the south one. Identical cold, identical air, opposite answers.
There is a reason, and it is the useful part. Cold tolerance in our care data mostly belongs to plants with outdoor ancestry, and those plants want a bright window. A drafty spot that is also dark has a genuinely small candidate list; a drafty spot with sun in it has a large one that no draft-tolerance article mentions, because those articles only consider plants sold as shade-tolerant. One row works at both: the spider plant is comfortable to 10 °C, does not mind moving air, and appears on no such list anywhere.
What the moving air does on its own
Hold a spot warm and change nothing but the air. A peace lily, a metre back from a north window, at 21 °C:
| How the air moves there | Verdict |
|---|---|
| Still air | Great fit, 94/100 |
| Light air | Great fit, 100/100 |
| Medium air | Great fit, 94/100 |
| Strong air | Worth a try, 67/100 |
Still air costs it as much as strong air. This dimension is a target rather than a scale, and both sides of it are wrong, which is why a sealed alcove is a real problem for a plant that wants a gentle current. Nobody looks for it, because a still corner looks like the safest place in the room.
What to do with your own drafty spot
Answer the light question first, because it changes the answer more than the draught does. The free spot checker reads the light at one exact place in your browser in about ten seconds, with nothing to install.
- Dim and cold. The shortlist really is short. Cast iron plant first, spider plant as the more available second.
- Bright and cold. Stop reading draft lists. Aloe, jade, echeveria and most succulents are comfortable to around 10 °C and are happier there than any of the four usual names.
- Above 16 °C. The draught is not your problem and nothing here is ruled out by it. Look at light and watering instead, which why plants die in winter covers.
The boundary: we estimate airflow rather than measure it, so treat that column as a bucket and not a reading. Light is the one we measure, by laying the phone down at the spot. Every score here is our engine run at the conditions printed in each table, and the floors come from our curated care data.
