Ligularia reniformis carries enormous glossy kidney-shaped leaves that give a shaded garden the bold tropical texture usually only available in full sun. The Tractor Seat Plant is grown for foliage first, with tall stems of bright yellow daisy flowers through summer as a bonus.
Ligularia reniformis forms a clump 0.6 to 1 metre tall and 1 to 1.5 metres wide, spreading slowly at 10 to 20 centimetres per year. That steady habit makes it reliable as a mass underplanting beneath established trees, an edging along a shaded path, or a single specimen in a large pot.
This is a full shade plant. It wants consistent moisture and protection from hot afternoon sun, which scorches the leaves, and it is frost sensitive, so in cold districts it needs a protected position. Given shade and water it is close to maintenance free.
Frequently Asked Questions
About Ligularia reniformis
How big does Ligularia reniformis grow?
It forms a clump 0.6 to 1 metre tall and 1 to 1.5 metres wide. The individual leaves can reach 40 centimetres across, which is where the bold texture comes from.
Why is it called the Tractor Seat Plant?
The common name comes from the large round kidney-shaped leaves, which resemble the seat of an old tractor. The botanical name reniformis means kidney-shaped.
Does Ligularia reniformis need shade?
Yes. It performs best in full shade and will scorch in hot afternoon sun. It is one of the most useful foliage plants available for genuinely dark positions.
When does it flower?
Tall stems of bright yellow daisy-like flowers rise well above the foliage through summer. The foliage remains the main feature for the rest of the year.
Is Ligularia reniformis frost tolerant?
No. It is frost sensitive and may be damaged by frost. In cold districts plant it in a protected position, or grow it in a pot that can be moved under cover.
How much water does it need?
It wants consistently moist soil and does not tolerate drying out. Mulch well and water regularly through summer, particularly in pots and under established trees where roots compete.
How far apart should I plant it for a mass planting?
Plant 0.8 to 1 metre apart for a continuous shaded groundcover mass. Closer spacing fills in faster but the clumps will crowd within a few seasons.
