Title: Gentiana
Post by: Blue-bellied Frog on August 04, 2008, 02:44:26 AM
I have some Gentiana grown from seeds and I'm not sure I always get what is suppose to be.
I hope someone can help me  for identification.
The first was named G.acaulis.

This one is G. przewalskii ?
I did not saw any picture on the Web.

Gentiana purpurea (the Great Red Gentian), autumn flowering, is not on this page, though I like the ones that are.

And the first one is certainly NOT G. acaulis which grows on a low mat and has a large, trumpet shaped flower, usually primary blue.

If you like to send me your postal address in a private email I can send you some reasonably fresh seed.

I will investigate your images tomorrow Bernard and try to identify them for you.

Cliff, I'm waiting.
Paddy, thanks you.
Lesley, sure I will.
Heather, I know it is not G.purpurea, but I would like to know is name. This Gentiana was my first try to have G.purpurea. My second and third try did not gave me any seedling. But I will try again and again until I Have it.

I hope this one have the good name.

According to Halda and 'The Genus Gentiana' - your G. macrophylla looks very feasible (though Jarmila Haldova's illustration shows more pronounced pleating of the leaves).
G. przewalskii is only listed as a variation of G. algida/ G. nubigena (subgenus frigida) and a quick scan of G. nubigena shows a plant and flower form that relates quite closely to your plant (though the detailed description states a 'bright blue corolla' ... ?
I will take a look at the other queries in the next posting.

Thank you Cliff.
First picture show base leafs of the G.macrophylla.
Others pictures show a Gentiana grown from seeds sold as G.Nikita Blue.
I saw somewhere it is G. dahurica. Is it right?
The last picture is not good, but it show whole-plant.

Hi Bernard,
Gentiana dahurica fits the bill exactly - Jarmila's illustration could have been captured from your very plant.

Where did you source your seed?

Having problems with your other images - there are so many candidates in Josef Halda's repertoire! Will keep on looking.

Bonjour Cliff,
Three pictures for G. not-acaulis, grown in full light shade (no sun, near a Rhododendron) (In 2001, I had few flower beds, and I did put some seedlings where there was room)
Base leaves are 26cm long x 3 cm large (max)
stem leaves are 13cm       x 4,5cm

Gentiana Nikita Blue seeds was from McKenzie.
Sown on 02/01/2002, began to germinate 02/13/2002
I still have the envelope  with some codes.
      NL
Lot A2
And after the name of their Web site, this number 122507.
(It is good to keep records, no?)

For this one I'm sure for the name.
Gentiana linearis, a plant I did save "In extremis" from tractor in a road reconstruction, on Mt. Valin.(50 Km. north from Chicoutimi)

Before I look TOO hard Bernard ... have you tried e-mailing McKenzie Seeds with a query - they have an in-house expert on their website supposedly?  Perhaps they have been asked the question previously?

Your G. linearis is superb!
Title: Re: Gentiana
Post by: Blue-bellied Frog on August 06, 2008, 03:48:53 PM
No, Cliff.
But I will, and will return with answer.
Yes this linearis is superb, but difficult to catch the true color. Always look "Luminous" on photos.

Nothing to complain about there Mark :)
Title: Re: Gentiana
Post by: Blue-bellied Frog on August 06, 2008, 10:49:11 PM
I would like to have this one too, Mark.
Me, I have only one bunch of Crocosmia. But that's give good flashing pictures.

Post by: Maggi Young on August 06, 2008, 11:10:55 PM
Bernard, if I could have humming birds in my garden I'd be growing lots of crocosmias and other plants to attract them! You are so lucky!
Title: Re: Gentiana
Post by: Blue-bellied Frog on August 06, 2008, 11:51:18 PM
They feed on almost all kink of flowers, Maggi.
It is a coincidence, today I was telling myself it was my lucky week.
I did photograph two dragon fly from approx. 3 cm.
So, a few minutes ago, I bought a lottery ticket :)

Bernard - So you are growing Lucifer outside. What are your lowest temperatures and do you have reliable snow cover?

Tell us more!

John, many gardeners in Québec are growing Lucifer outside.
I'm in Zone 4B but my garden is well protect by trees in a valley.
My Crocosmia did past 3 winters without problems, without any mulch or other winter protection.
Last winter, we finish with 2 meters of snow. But three winters ago, we had only 30 cm of snow on ground, plus three periods of rain over winter, and no snow cover before January.

They are on the top of the wall (on the left of the picture).
From the water table (This spring) to the top of the wall, there is 12 feet of sand. So, we can say it is well drain location.

Thanks Bernard. I guess that tells us just how important snow cover is - you zone 4 and I am having problems in zone 6. 

Yes I'd say you are well drained !
