Mini spider plant as drawn in the simulator

Mini spider plant

Chlorophytum comosum 'Bonnie' (young)

BeginnerFine in a closed jar

Arching striped leaves. Shrugs off most mistakes.

What the simulation uses

Light
1,500 to 15,000 lux
The brightness it grows well in.
Humidity
40 to 90 % RH
Air moisture it is happy in; below the lower end it dries out.
Temperature
13 to 27 °C
Comfortable range; outside it growth slows.
Dies at
below 2 or above 33 °C
Days beyond these temperatures kill it.
Soil pH
6 to 7.2 pH
Soil acidity it prefers.
Grows up
1 cm/month
How fast it gains height in good conditions.
Spreads
1 cm/month
How fast its edge creeps outwards.
Copes with wet
fair
How well it stands soggy soil; poor means rot comes quickly.
Copes with still air
excellent
Sealed jars have still air; poor means grey mould finds it.
Copes with shade
good
How well it holds on in dim light.
Copes with drying
good
How well it survives the jar drying out.
Water use
0.06 ml/cm²/day
Water drawn up from its roots per cm² of leaves in room air; a sealed jar cuts this to a fraction and returns it down the glass.
Leaf drop
2 %/month
Share of its leaves it sheds each month as litter for the cleanup crew.
Soft leaves
no
Soft new growth that hungry isopods will nibble.
Full size
17.5 cm tall, 25 cm wide
Its size when grown, before the lid stops it.

Care

Day length
10 to 14 h
Substrate
Moist

What kills it

Description

Growers report it coping even in a bowl with mould in it. A small spider plant is easy to please. It tolerates a wide range of light and humidity, so it suits a first jar.

Also called spider plant, airplane plant.
