How to Grow Twinleaf & Rheumatism Root
It is best to grow Twinleaf, Rheumatism root and other Jeffersonia members outdoors.
They should be sown using fresh seed at the beginning of autumn into flats containing rich, peaty soils.
Once sown lightly cover the Jeffersonia seed with soil, then place the flat in a shady part of the garden, and keep covered in glass.
It can take two years to germinate the seeds so be patient. During this long germination period, be sure to keep the soil moist.
Once seedlings of Rheumatism root emerge, they should be planted about 15 to 20 cm (6 to 8 inches) apart into a shaded part of the garden.
It is important that the soil is not limy, but a rich and peaty wood soil.
Caring for Rheumatism Root, Twinleaf, and other Jeffersonia plants in the Garden
It is best to mulch the plant in order to keep roots cool. Jeffersonia will not grow successfully in hot areas.
If you require more plants then they can be divided in the spring or autumn once established.
