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 apart into a shaded part of the garden. It is important that the soil is not limy, but a rich and peaty wood soil.
