This is a species from China that grows at altitude. It is best pot grown so it can be protected from rain when the temperatures are high in the summer. The rhizomes offered are multibudded and are typical of the species in that the roots are rather short.
The plants are sent out to customers in the UK in two litre pots in a suitable mix which enables the purchaser to either grow the plant in the pot in a cold frame or it can be plunged in the soil in a cold shady spot. Plants are sent out from October to March whilst the plants are dormant
