Hi,
I grow Dr erythrorhiza ssp. magma, Dr. erythrorhiza (unknown) and Dr. erythrorhiza ssp. imbicella and the last one gives me headaches...
It does not build tubers under my conditions. All of my other tuberous plants seem to build tubers except this *%$!+'# spezies...
It builds some kind of thick "rhizome". Last year I replantet this rhizome imiditaly but this year I placed it in a plastic bag...
They have to grow in winter !!!! ... grrrrrr....
I grow my plants in a cold room with a south facing window and some artificial light (~2 hrs) from a 250W high pressure sodium light but the plants don't grow very well :-(
(except the auriculata which reached more than 90cm this year).
I would highly recommend to start with "easy" tuberous Drosera like menziesii, peltata, auriculata, (whittakeri)
The ssp. magma shown in the picture is new from Lowrie and is still growing (adepting to northern hemnisphere)
maybe someone knows, to which subspezies this plant belongs :
