Hi Kay, mostly I have seen it as a hybrid with a non-rhizomatous Celmisia like C. spectabilis, though I imagine it can hybridise with C. viscosa, and the leaves on your image do have some features that look like C.viscosa. Only way to know for sure would be a close examination of leaf surface and margins and the flower stalk (or genetics!). However, Celmisia's can hybridise with a range of species
