Twenty-five years ago a nursery I used to visit (now closed) had a five-year waiting list for this plant, which was eye-wateringly expensive.  This is a testament both to its popularity and to how slow it is to increase.  No photograph can convey the intense redness of the flowers, as luminous as glowing embers.  Micropopagation has made the plant widely available but, despite its former scarcity, it is not difficult to propagate from the fat nodule-like growth on the roots, you just don’t get very many per plant.  It is a hybrid between P. lobatum and P. fulgidum, which is the same cross that also produced P. ‘Schottii’
