P. lutea grown from seed /different looking plants

[daniel]

Hello,

one and a half year ago i sowed a small number of seed (about 25) of P. lutea ´US Hwy 19N, Hudson, Pasco Co., Florida, USA´ (if the location is correct), the plants have germinated relatively fast (about 3-4 weeks) on dead sphagnum and have grown without any problems and all in all i have had 12 adult plants.
1 month ago i gave 4 plants away because of space problems, so i still have 8.

To come to the point, one plant is looking very different in my eyes, the other 11 plants are looking very similar, with wider leafes. All plants are about 14cm (5,5 inch) in diameter but they have not flowered yet.
I have taken some pictures with one of the very similar plants and the one that is looking very different, it seems so that there is some kind of variation, the growth form is different from the beginning of their growth.
Sorry for the qualitiy of the pictures, but i only wanted to show the difference between them.



And here is a picture with a third plant that is looking a little bit "intermediate".

I wonder if the flower will also look a little bit different, or is there perhaps some hybridisation.

Bye the way Brian, are P. lutea also growing partially submerged for some time of the season?

Best regards,

Dani

Hi Dani,
First off, your Pinguicula lutea look wonderful and I believe your location info is correct. I've seen them in that area before and it's about 40 miles or so from my home. The mentioned area is also home to Pinguicula caerulea.
Is that sphagnum you are using as substrate? I grow mine in blond Chilean sphagnum and for some reason, they thrive in it...
I've seen the same thing happen with mine as is occurring with yours. It will be very interesting when they do flower!
In situ, I've noticed that P. caerulea usually has longer, more elliptical leaves than P. lutea and at one time, I entertained the idea that one could ID the two species without flowers present, based on these differences...
Since the species are known to grow within close proximity of each other, wouldn't that be something if your one plant turned out to be P. lutea 'alba' or P. caerulea instead? ;D
Speaking of Pinguicula lutea 'alba', I have around 30 or so nice-sized seedlings ready to go into sphagnum. I'm hoping that the white-flowered trait will hold true to some extent and that I will to be able to offer some seed for trade in Spring!

I've never seen P. lutea, P. caerulea of P. pumila growing submerged in situ, although I have seen them very wet at times. They seem to like their conditions a bit drier and tend to prefer very fine, sandy soils on slightly higher areas, with P. pumila enjoying conditions even slightly drier.
Happy Growing,
Brian.

hello DANIEL

very nice picture and plants

you have for the leaves width caracter from 0.6 to 2.4 cm then this winder form seem to me normal.

wait for the flower

BRIAN on the exact composition of the substrate and its mode of culture is more capable knowledge, but according to what I have seen by it on “in situ” picture, the medium is completely different and much drier, it is a plant nevertheless very sensitive to the moisture of its roots.

the cultivate method by william DAWNSTAR in 2002 , I hope BRIAN agree ;D.

Thanks Jeff and Brian.

Great to have such a location only 40 miles from your home and interesting to hear that there is also growing P. caerulea.
Normally i would also say that the wider leafes seem to be more normal.
The left plant is a little bit looking like P. caerulea, but it´s much bigger than a P. caerulea i´m growing.
How big in diameter is P. caerulea getting in nature?

Yes, it´s dead sphagnum they are growing in, after they have germinated so fast in dead sphagnum i´ve devided the plantletts after 2 month of growing and planted them again in dead sphagnum.
I know that the substrate is totally different in comparison to the substrate in nature, so i don´t know why, but somehow they seem to like this substrate and they seem not to be very sensitive to the moisture.

If the one would be P. lutea 'alba' it would be indeed very interesting, who knows. ;D

I hold my fingers crossed that your P. lutea ´alba´ seedlings will hold the white-flowered trait true to some extent, this would be really fantastic and in this case of course i would be very interested in a seed trade.

Thanks for the information that they are never growing really submerged, i´m growing my P. lutea in 5x5cm pots (i know they are much too small) and the waterlevel is about 0.5-1cm.

Best regards,

Dani

[jeff]

for one P. caerulea leave
length between : 1.4 to 6.6 cm
width between : 0.6 to 2.3 cm

in diameter then 2.8 cm to 13.2 cm

in dead sphagnum perhaps the moisture are lesser but in sand+peat substrat like 'in situ' ,yes , that thinks about it BRIAN ?

the exact taxonomy name from this P. lutea 'alba' is P.lutea f alba ;D (see the FOLKERTS & FREEMAN document)

f = form notion

in taxonomy you have 4 infraspecific rank : sp , subsp , var , f ;but I think you know ;D
we must remained precise on the name not of derived please which could claim has confusion for the futur .

I am also taker for these P.lutea f alba seeds

[Brian Barnes]

Thanks Jeff,
I forgot the "f" ;D

Dani, I've seen Pinguicula caerulea get up to 5 inches 'in situ' and have grown them to that size myself...They do experience much drier conditions in Winter time, which seems to be when they are less tolerant of too much wetness and more prone to fungal attack. Interestingly though, P. planifolia don't seem to mind occasional flooding in Winter, since they grow in lower ground/high water table areas. I look forward to seeing yours flower!
Happy Growing,
Brian.

[daniel]

Hi,

Brian, i have only one plant of P. caerulea, but it´s only about 2,5 inches and it seems to stay at this size. It also has these not so wide leafes.
And about the humidity, yes, i´ve lost 2 years ago a plant because of a fungal attack, so this winter i will let it grow a liitle bit drier.

Yesterday i checked the plants again and to my surprise i saw this, one of the plants with wider leafes is starting to flower these days.

I hope the others will do the same soon.

Best regards,

Dani

[Brian Barnes]

Hi Dani,
EXCELLENT! It's ironic that you noticed that...
Strangely enough, My P. planifolia are putting up spikes too. They are a few months early, which is quite odd. Maybe your plant knows we are talking about it! ;D

Happy Growing,
Brian.

[daniel]

Hi Brian,

yes, very strange that it will start to flower these days.
I´m very excited how it will look like and if the other plants will start to push spikes too.

I´m also growing 3 other plants of P. lutea, 2 with unknown location and one from ´Citronelle´ that have flowered last winter during February. During December and January P. ionantha and P. primuliflora have flowered.

And yes, i think you are right that it perhaps has started to flower because we are speaking about it. ;D

Interesting that your P. planifolia have also started to flower too, perhaps it´s the global warming. ;D

Next week i´ll post some pictures from the opened flower.

Best regards,

Dani

Hi all,

a small update from the emerging flower.





But this was not the reason for my post, the reason is this.





I have never seen something like this before that there are "drops" under the leafes, they are directely in the middle of the leafes, in fact under the middle vein.
After i saw this i checked all plants and only 2 of the plants have the "drops" on all of the leafes. My 2 other clones don´t have these "drops".

Has somebody observed something like this, or does something like this happens often?

Best regards,

Dani

[jeff]

magnifique

nature some time brings his batch of surprises to us, I rather often note it 'in situ' and 'ex situ'

[Brian Barnes]

Hi Dani,
Looks like you'll have a nice flower! Hmmm...I'll have to check mine closely, i've never noticed tentacles under the leaves. Really fascinating....
Brian.

[daniel]

Hi all,

yes, for me it was the first time i´ve seen these tentacles under the leaves, from now i will check them more often.

Brian, have you checked your plants for these tentacles under the leaves?

The flower is fully opened now, so it was time to take new pictures.













And for comparison here are flowers from 2 other plants without location data from last winter (their rosettes are much smaller ).
The first one has had a bigger flower, the colour was also slightely different.

The second one was perhaps a little bit smaller a more fuzzy (sorry for the picture quality, but i had to take this picture last winter with my very old camera, because my new one was damaged)


Best regards,

Dani

[Brian Barnes]

Hi Dani,
Gorgeous flower! I've checked my plants and I have no tentacles under the leaves... Maybe you have a cross with D. filiformis! ;D
;D
;D

Happy Growing,
Brian.

[jeff]

magnifique , DANIEL
we can see also on a corol lob some disgestives glands ( pic 3 and 4), it is a dream or not

can you take a picture from the sepals ,please , to see their form ?
