Sedum morganianum

EasyOpen jar only

Plump leaves stacked along hanging stems. Drops leaves if knocked.

What the simulation uses

Light
8,000 to 40,000 lux
The brightness it grows well in.
Humidity
20 to 50 % RH
Air moisture it is happy in; below the lower end it dries out.
Temperature
13 to 29 °C
Comfortable range; outside it growth slows.
Dies at
below 5 or above 35 °C
Days beyond these temperatures kill it.
Soil pH
6 to 7 pH
Soil acidity it prefers.
Grows up
0.65 cm/month
How fast it gains height in good conditions.
Spreads
0.65 cm/month
How fast its edge creeps outwards.
Copes with wet
poor
How well it stands soggy soil; poor means rot comes quickly.
Copes with still air
poor
Sealed jars have still air; poor means grey mould finds it.
Copes with shade
poor
How well it holds on in dim light.
Copes with drying
excellent
How well it survives the jar drying out.
Water use
0.02 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
yes
Soft new growth that hungry isopods will nibble.
Full size
7.5 cm tall, 60 cm wide
Its size when grown, before the lid stops it.

Care

Day length
6 to 12 h
Substrate
Dry

What kills it

Description

Its leaves fall off at the lightest touch, so place it where you will not brush against it. It wants bright light and soil that dries out completely. Still, humid air rots the stems.

Also called donkey's tail, burro's tail sedum.

Estimated, where sources were thin: no species-level lux study found; ranges from succulent care guides.
