It seems the less fuzzy species (D. paradoxa, D. falconeri) seem to propagate fairly easily as leaf pullings floating in water and kept in my case relatively warm. Also clumps of leaves from D. paradoxa seem to produce more plantets and appear to have a greater percentage of being successful. However, the more fuzzy species (D. lanata) do not seem to be as easy in terms of leaf pullings. So far the only way I was able to get them to propagate was to wait for the plants to divide naturally and then remove and transplant the offshoots. Most discussions suggested that leaf pullings were not that successful and taking clumps of leaves difficult to remove intact. I had read accounts of other species being propagated by taking a sharp knife or razor blade and carefully slicing the plant into multiple sections and that increased success could be found by having the sections contain a portion of the plants root system. So, I had a plant that had naturally divided . I split it up and one plant was quartered with a sharp knife. These quartered sections were planted back into a quick draining petiolars group compatible mixed, as if they were individual plants, and held in standard petiolars sundew growing conditions. The second plant was replanted after harvesting some leaf pullings. It was difficult to get get them to come free in clumps. Got one clump and a few lose leaves.
the clump of leaves attached together is developing plantlets. As are a very few of the lose leaves. It seem that the lose leaves developing plantlets do have a fairly large part of the stem attached.
The plant that was quartered appears to be developing multiple plantlets per quarter.
Might be too early to say for certain but it looks like quartering the plant and replanting it is going to be fairly productive. maybe 2-3 plantlets per section.
