Other thing about tuberous sundew seeds, many WA species need special techiques to get germination. Put simply they need a bushfire. Reasons are several the fire clean the overhead vegetation, produce fertilzer (ash) and release chemicals in smoke which trigger germination. On top of this it can take three years for germination.
Good news is some species such as gigantea do not need the above conditions. Other species are to easy germinate from personal experience(if you live in a warm temperate area) are auriculata, peltata, macrantha ssp planchonii, stolonifera ssp stolonifera, ssp rupicola, mooreii, whittakerii ssp whittakerii.

The chemical needed to induce germination is called Ethylene. Drosera stricticularis is another species that self pollinates and germinates easily. Found in Western Australia and Port Lincoln in South Australia.
