# Burro's tail
Sedum morganianum

Easy · Open 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

- overwatering / stem rot
- humid still air
- physical knocks (leaves shed easily)

## 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.
