Plants

Shingle plant as drawn in the simulator

Shingle plant

Marcgravia rectiflora

ModerateClosed jar only

Flat leaves that shingle up bark and glass in a humid tank.

What the simulation uses

Light
1,500 to 8,000 lux
The brightness it grows well in.
Humidity
70 to 100 % RH
Air moisture it is happy in; below the lower end it dries out.
Temperature
18 to 29 °C
Comfortable range; outside it growth slows.
Dies at
below 12 or above 33 °C
Days beyond these temperatures kill it.
Soil pH
5.5 to 6.5 pH
Soil acidity it prefers.
Grows up
0.4 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
good
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
poor
How well it survives the jar drying out.
Water use
0.04 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
1.5 %/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
6.5 cm tall, 37.5 cm wide
Its size when grown, before the lid stops it.

Care

Day length
10 to 14 h
Substrate
Moist

What kills it

Description

This climber needs very humid air, so it suits a closed tank. It is slow to settle in after planting, then grows steadily. Give it bark or a back wall to climb.

Also called shingle vine.

Estimated, where sources were thin: rates and limits are horticultural estimates, not measured.
