Title: Gentiana sp..
Post by: Jonna on August 16, 2016, 08:44:58 PM
[attachimg=1]I got the seeds of this plant as Gentiana depressa, but in my opinion it's not.
Any help to identify this one is very welcome.

Lovely plant wonder if it is cruciata?

Definitely not depressa, sadly! I think cruciata is probably right.

I was wondering the same thing about my seedlings. Seed came from both SRGC and NARGS seed exchanges, and ended up being identical to what you show here. Thank you for the identification!

I wouldn't be so fast to proclaim it G. cruciata until further consideration. There are other Gentiana ssp. in the Sect. cruciata that can pass as cruciata, to mention just G. macrophylla.
If the provenience of seeds is known it would be easier to say; otherwise a look at the calyx and few other details...

Was this from the 2010/11 seed exchange or later.  I sowed seed of Gentiana depressa in January 2011 from SRGC and got this.  I did not grow it to flowering stage.  It was composted as soon as I realised it was not depressa.  I hope it is not still turning up under this name.

Thank you all for the replies.

If I google pictures of G. cruciata, I see often flowers all along the whole stem. My plants only have flowers on the top of the stem or just below.

If I google G. macrophylla, I read that that one flowers in August/September. My plants flowers in July. I'm in zone 6b, mostly a late start of spring.

The plants are on a rather dry spot in my garden. They are a bit floppy after flowering, but not as  as floppy as G. gracilipes.

I got the seeds in the SRGC seedexchange 2010/2011  or 2011/2012

Could it be willow gentian, G. asclepiadea.

I've passed a note to the Seed Team which I hope they will  check out and bear in mind for this year.

G. asclepiadea is something totally different.

And another note:

Gentiana gracilipes is a syn. of Gentiana dahurica for quite awhile and shouldn't be used anymore.

Still waiting for an ID.  :)

I was checking out some of my plants in my cold-frame this afternoon and noticed this plant which I think is some type of Gentiana sp.? It somehow sowed itself in a pot with a Lewisia cotyledon which is a bit of a mystery since I have never knowingly sowed it there. Does anyone have any idea what type of Gentiana it is? I think it may be some type of G. paradoxa or maybe a G. Sino-ornata. I've tried sowing both previously with no known success.[attach=1][attach=2][attach=3][attach=4]

Lovely Gentiana paradoxa, Rob - or perhaps a hybrid - hard to say exactly since it is somewhat promiscuous.

Very nice gentian, Rob. Looks like Gentiana paradoxa from the photo and it's blooming the same time as mine.
Title: Re: Gentiana sp..
Post by: Gabriela on September 12, 2016, 06:19:55 PM
Yes, you lucky man! G. paradoxa (or a hybrid, but nice narrow leaves).
Title: Re: Gentiana sp..
Post by: Jonna on September 12, 2016, 07:30:07 PM
The leaves of my plants are not as narrow as the G. paradoxa.
Title: Re: Gentiana sp..
Post by: Gabriela on September 13, 2016, 07:16:42 PM
Jonna,
Do you mean you also have Gentiana paradoxa but the leaves are not as narrow? As Maggi said, in culture G. paradoxa is promiscuous and you can obtain offsprings with variable foliage.

If you are talking about your first Gentiana - do you have more close-up images?
Title: Re: Gentiana sp..
Post by: Jonna on September 13, 2016, 08:58:58 PM
Gabriela,
I don't know if I have Gentiana paradoxa. It's very confusing to me. Do you think mine is G. paradoxa?
I do trade and sell my seeds, but I don't want to do that with a proper identification.
I don't have other close-ups from the plant.

I do have other Gentians and I have no doubts about their name:
- Gentiana verna alba
- Gentiana tibetica
- Gentiana gracilipes
- Gentiana pneumonanthe
- Gentiana flavida

No Jonna. We were talking about Rob's G. paradoxa, which is very distinct.

Yours can be quite a few others but not G. paradoxa. It is no way to say what species it is only after the few images. I already said that there are a few Gentiana spp. that look very similar at a superficial look, and you need more details to be able to differentiate them. It is a very good idea not to 'spread' the seeds until you know the name. Next year take close-up pictures right when it starts to flower.

At the link below you can see many pictures with Gentiana cruciata taken in the wild (also write Gentiana macrophylla in the Search and you get that one too).
