Primulina linearifolia

Sorry, no flowers at the moment and too elongated leaves because of low light.

Too enormous actually, elongated because of a lack of light. I am re-rooting it now to get a better/more compact plant again (pulled of almost all leaves and cut the top 6 cm of stem, and planted this with a very small crown). I will show the result when it looks like something again. I also planted 3 leaves. My impression is that they take longer than a violet, but are equally easy.

Laci, you can bring some leaves in country, and maybe someone else will be interested in growing it.
By the way, for example, our Botanical Garden in Bucharest is very interested in all kinds of species they don't have.

It is a year(!) after planting my last leftover leaves, and only now I got two small plantlets growing from the last remaining piece of a leaf. They are still fragile, but perhaps I can keep growing this interesting species :D

This plant is relatively easy to grow from suckers, but can take a lot of patience when growing from leaves ...

I think this applies to all Primulina plants. Well said. :)

It is alive and well in my collection, still small but growing steadily. Still no suckers to give away, still no flowers.

Some months ago it was looking like it didn't doo much and I repotted it. It had only few roots so I scraped the lowest part of the stem a bit and poot some rooting hormone on. I think that this helped :mrgreen: This plant is really testing my patience, but I really intend to keep it going!

It's by now flowering of and on and I also planted cut of suckers on a piece of tufa rock - also these appear to start growing. Will place pictures in some time.
