I know that some people don't have that much luck with P. primuliflora as I do so I decided to show some of the different ways that I grow it, because I think that that might be one of the reasons.
Here's a pot of a little bit of everything, some P. primuliflora, D. intermedia, D. filiformis ssp. filiformis "all red", and some U. bisquamata that is 1 part peat 1 part perlite.
here's my second Mother plant that I grow in 100% peat moss with live sphagnum growing at the top.
here's my first Mother Plant that I grow in a tall pot with again 1 part peat one part perlite
Here's two that I decided to just try to grow in the hole of a chia pet that is accompanied by a little bit of live sphagnum and a D. filiformis x California Sunset
