Hi Matt & all, My experience is with Commelinaceae in general, many species have come by in 30+ yrs. Root propagation of Tradescantia like types usually is well possible but not by cutting pieces of roots. When plants are dormant the root system can be “cleaned” from most substrate and then one needs to take a close look for buds, usually on top of one or a group of roots (fusiform roots?). These can all be potted apart and each can form a new plant. Some species have 20-30 cm long roots, pot these in deep pots, the bud just under soil surface. Pruning of these long roots is possible but the cut off part can not be used for propagation, I prefer to leave all stored energy in the root(s) to give the propagation a better chance.

I?ll be interested to know how you go with the root propagation. I also tried taking a root cutting after a length of its brittle root system snapped off while repotting (6m ago here in winter in Australia). It has sat unchanged for around 6 months; no visible growth but no deterioration. > > I was fortunate enough to source my Weldenia from a brilliant grower here in Tasmania called Sally Johannsohn, which is no help to anyone outside of Australia, I?m sorry. > > I think Martin is right, the limited means of propagation is, no doubt, why they are so expensive. I have been hunting for seeds for quite some time, as I would love to increase the genetic diversity of mine. As far as I?m aware there are next to no seeds formed in cultivation? I suspect virtually all Weldenia in trade has been vegetatively propagated and are almost all clones. Perhaps someone else has thoughts on this? > > Fwiw I grow mine in large containers with regular potting mix that has around 20-30% of coarse grit added for drainage, which I?ve found to be paramount. Winter wet/drainage has always been a greater challenge than temperatures (I get down to -13?/8f). > > Matt > > Sent from my iPhone > >> On 15 Dec 2021, at 11:00 pm, pbs-request@lists.pacificbulbsociety.net wrote: >> Hi, >> It seems that a propagation method is "true" root cutting.
