Gentiana triflora is growing well, and it is very tall this year.
The second and third pictures are of a plant which I have grown from seeds. The mother plant was bought from garden center (label lost), so it shouldn't be anything rare, but I can't find what species this my plant is. It's flower shape is the same as G.triflora, but leaves are smaller and thinner, and the whole plant is much smaller, about 30cm tall (while G.triflora is maybe 1,4m tall).
Any ides what this plant may be?

The second two photos are most likely G. asclepiodes

Leena, I think it is  Gentiana pneumonanthe.

Herman, you could be right. I googled it and G.pneumonanthe is for sale in Finland, and it looks mostly like my plant. I will have to wait if flowers of my plant open more.
Gentiana asclepiadea is different  :), I have it in several beds. It is a very good plant for shady borders, and it is starting to flower soon.

Wow Leena, you can tell it was raining well where you live! G. triflora grew quite a giant :)
I had few seedlings which disappeared fast in early May when we had the first surge in hot weather (same happened with few other seedlings).

G. pneumonanthe is also beautiful. One G. asclepiadea I have is not taking well the drought, despite my occasional watering, I have to move it in a more appropriate location later in the fall.

G. paradoxa,G. septemfida and hybrids between them are starting to flower. This clump of various seedlings planted together is my favourite:

Does anyone have any tips on increasing the blooms on my Gentiana angustifolia, or perhaps diagnosing the cause of their shyness? I planted seed-raised specimens a few years ago, many of which are now (relatively) substantial clumps. So far they have only produced a grand total of 3 flowers in total! :( Some notes on their growing conditions:

- 6 hours direct sun (afternoon shade)
- Well-drained soil
- I live in a cool climate, with temperatures rarely exceeding 33
- Have used decent quality slow-release fertiliser

Do I just need to go harder with the fertiliser, perhaps use something with a different NPK value?

Any tips would be greatly appreciated!

Gentiana asclepiadea started to flower here in late August and they are still flowering. All of them are grown from seeds and there have come up different colours though most are blue.
White one has small spots in the flower so it isn't pure white. Should it be pure white?
The one with lilac colour is also nice. :)

Magnifique!  ;D
I only have a young white flowered form that almost perished this summer. I don't know if only from drought, or something else going on with it.
But if it does so well in Finland it may be that it needs much more moisture and dislikes our hot summers.

Perhaps it needs moisture, and it isn't so hot here are what you have.
It has done well in my garden, and I have it growing in many places. Even in clay and wet it survives.
This lilac form was still flowering last week in more shady spot.

Perhaps the last Geniana acaulis flower in this year is this big flowered cultivar,
a gift from a Czech nurseryman.

I can only dream about something like this Herman! Such a great plant for the fall garden.

Gabriela, do you know a source of Gentiana sino-ornata or other Asian autumn gentian plants or seeds in Canada?

Your guess is as good as mine 'corydalis'. Try to look after a nursery or a Rock garden group seeds exchange from Western (BC) or Eastern Coast (NS, NB). These are the places where you can grow this Gentiana.

Just a few days ago it was warm and the young G. paradoxa was looking very beautiful. In a couple more days we may receive the first flurries of the season  :'(
