Gail, I was in that garden in 2015. Now seeing this movies, there is a desire to go back to Norway. But traveling is not allowed in Belgium because of corona.

Thanks Herman. Fantastic videos with these Himalayan Gentians.
They look amazing even with ice crystals!

So many Gentians with you already Herman! I'm surprised that even G. angustifolia is in flower.
I never managed to keep G. acaulis because of the substrate requirements but it seems that I may be successful with G. clusii.
G. clusii a violet form, grown from seeds :)

Gabriela, they like nutritious loamy soil. Angustifolia also loves some lime.

Yes, I know Herman. G. clusii and G. angustifolia are good for calcareous substrates. On the other hand, G. acaulis only grows in the wild on silicaceous substrates in the wild, reason why it is more difficult to accommodate in culture.

In this light, you may want to have a closer look at your labels. It is very unfortunate that plants are sold with wrong names. I personally enjoy them regardless, but it is always good to double check the names.
G. clusii lacks the green spots inside the corolla (reason why I posted a close-up, hoping that people will observe).
G. acaulis, is a stemless species; likely that the ones you show are G. angustifolia or hybrids, with the exception of the white one.

Gabriela, there are indeed a lot of misnamed Gentiana. G. angustifolia has the right characteristics: the old leaves are long and very narrow. The bell and chalice also have the correct shape.

Hmmm... so how do you distinguish between G acaulis said and angustifolia? Acaulis does have a flower stem, doesn’t it - short, but a stem all the same?

Carolyn, the name, Gentiana acaulis (stemless gentian) is used in 2 ways: on the one hand as a group and on the other as a species.
You can see it here: http://www.gentians.be/index.php?page=articles&art=9



You can see that the real Gentiana acaulis (as species) has broad old leaves, also look at the shape of the chalice and teeth. You see a white membrane between the teeth.
