Daniel O. Posted October 31, 2008 Report Share Posted October 31, 2008 (edited) Hi all, first the history, 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´, 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, all germinated seedlings have survived. A few months ago i gave 4 plants away because of space problems, but i still have 8. To come to the point, one plant is looking very different in my eyes, the other 10 plants have been looking very similar, with much wider leafes and one "intermediate". All plants are about 14cm (5,5 inch) in diameter but they have not flowered yet, till now. It seems so that there is some kind of variation, the growth form was slightely different from the beginning of their growth. Sorry for the qualitiy of this picture, but i only wanted to show the difference between the rosettes. I hope that the flowers will also be slightely different. And now the flowers (it´s one of the plants with the wider leafes), normally they are flowering later in the year. emerging flower The fully opened flower the sepals 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. Here are a few more pictures from it: North American Pinguicula in flower The second one was perhaps a little bit smaller and 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) And here another interesting point, I have never seen something like this before that there are "drops/glands" 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/glands" on all of the leafes. My 2 other clones don´t have them. a little bit closer Best regards, Dani Edited October 31, 2008 by Daniel O. Quote Link to comment Share on other sites More sharing options...
Marek Míča Posted October 31, 2008 Report Share Posted October 31, 2008 Very nice photos. Thanks. Those drops on the bottom side of leaves are interesting. I have never seen it on a picture. ;) Quote Link to comment Share on other sites More sharing options...
MarcelvW Posted October 31, 2008 Report Share Posted October 31, 2008 Very good photo's I have sowed some seeds last Spring, but none of them germinated. Perhaps they will this spring. Did you give the seeds a special treatment? Quote Link to comment Share on other sites More sharing options...
Daniel O. Posted October 31, 2008 Author Report Share Posted October 31, 2008 (edited) Many thanks Marek and Marcel. Marcel, i don´t have given them a special treatment. I have sown all of them on dead spaghnum in one round 5,5cm pot, watering by the tray method (about 0,5-1cm). The pot was standing in one of these green mini-terrariums under articial lights. After 3-4 weeks they have germinated and than i have devided them very carefully. At the same time i have also sown seed from P. planifolia, ionantha and caerulea, but nothing has germinated, so i think the seed was not fresh enough. After my experiances USA-Pinguicula seed is not viable for a long time, so if your seed has not germinated till now.... But i have also heard from P. planifolia seed that has germinated after half a year, so if your seed was fresh it can still germinate. Is in your pot growing some kind of moss? That was the reason why i have choosen dead spaghnum as substrate. Best regards, Dani Edited October 31, 2008 by Daniel O. Quote Link to comment Share on other sites More sharing options...
MarcelvW Posted October 31, 2008 Report Share Posted October 31, 2008 Thanks for the answers. I have some algae and moss in on the substrate. I sowed the seeds in a peat : sand mix: 50:50. I got the seed from triffid nurseries, I don't know if it was fresh. Perhaps the next time I will have more luck :) Quote Link to comment Share on other sites More sharing options...

LJ Posted October 31, 2008 Report Share Posted October 31, 2008 Interesting thread Dani and nice to see some details about the plants. Really excellent quality of photo's too! Would you mind if I asked what camera you are using? Heather Quote Link to comment Share on other sites More sharing options...
kisscool_38 Posted October 31, 2008 Report Share Posted October 31, 2008 Very nice pics with very nice colours. Have you notice those glands on other north american species? I'll check my P. primuliflora and P. pumilla tomorrow, that's an interesting point I haven't paid much attention before. Quote Link to comment Share on other sites More sharing options...
Vincent Limbourg Posted October 31, 2008 Report Share Posted October 31, 2008 Nice pics you've got there, Dani! P. lutea is definately one of my favorites, especially with those yellow flowers! I'll try to post some pics of mine tomorrow. Greets, Vincent Quote Link to comment Share on other sites More sharing options...
Daniel O. Posted November 1, 2008 Author Report Share Posted November 1, 2008 Many thanks , Marcel, normally your substrate is the right one, in nature they are not growing in dead/living spaghnum, but some years ago i recognised after bad experiances that moss is the biggest enemy for germinating seed, not only for Pinguicula, for other species like Drosera and Genlisea as well. It should be possible to pick small seedlings and plant them into peat/sand, perhaps it´s even better, but i think that´s better to sow them on dead spaghnum. Heather, my camera is nothing special, it´s a Panasonic DMC-FX07. I´m taking a lot of pictures and than i have to choose the sharpest. Aymeric, no, i´ve not noticed those glands on other north american species till now, only 2 plants have these glands and in this case all of the leafes have them, the others from the same seed not. 3 of my other clones of P. lutea are also not having these glands. I´ve also checked my other species like P. caerulea, planifolia, primuliflora, primuliflora ´Rose´ and ionantha, but they don´t have them too. But i must say that i have noticed them in the pictures after i´ve checked them, not before. Vincent, you are absolutely right, i also like this species for this really nice yellow colour, the only Pinguicula with such a colour. Of course i would like to see pictures of your plant, i hope it´s growing good for you and the 2 P. primuliflora ´Rose´ too.

Kiwi Earl Posted November 1, 2008 Report Share Posted November 1, 2008 Tremendous photo essay on lovely plants. Thanks Dani. Quote Link to comment Share on other sites More sharing options...
Vincent Limbourg Posted November 1, 2008 Report Share Posted November 1, 2008 Here's mine, one of Dani's seedlings by the way! My apoligies for the bad quality of the pictures, it's time to get a new camera! Dani, your plants are doing great. Also the Drosera's seems to like their new habitat! The Pings are recovering well, and they started with their new growth! P. primulifora 'Rose' already started to produce some little plants. Are you going to pollinate some flowers of USA-Pinguicula? PS: If you have some new plants available, let me know something! Greets, Vincent Quote Link to comment Share on other sites More sharing options...
jimscott Posted November 1, 2008 Report Share Posted November 1, 2008 Great job and incredible pics! Aside from P. primuliflora, I can't keep the N.A. pings alive for more than a few months... and i don't know why. Quote Link to comment Share on other sites More sharing options...
Daniel O. Posted November 1, 2008 Author Report Share Posted November 1, 2008 (edited) Many thanks to all of you, Vincent, your plant looks good as well and perhaps it will flower soon too. Also good to hear that the others are growing good as well. I have tried to pollinate it (no cross pollination because only this one is flowering in the moment) and i hope i was successful, the flower has fallen down yesterday and it seems so as if the capsule is beginning to swell, but later this year i hope that i will manage to cross pollinate some of them. But of course i will also try to pollinate my other U.S. species like P. ionantha, planifolia, primuliflora and caerulea. Of course i will let you know when i´ll have some new plants available. Jim, in my opinion P. primuliflora is the easiest from the U.S. Pinguicula and it is the only species that is propagating itself through the "production" of little plants and the end of their leafes and watering by the tray method all the year. In my opinion P. ionantha is also relatively easy to grow, i´m growing it by the tray method all the year. The others are a little bit more difficult because of the watering, in winter the substrate should not be to wet, except P. planifolia. Best regards, Dani Edited November 1, 2008 by Daniel O.

ada Posted November 2, 2008 Report Share Posted November 2, 2008 Dani, you should be succesfull with your pollination.I have one for the past 4 or 5 years and have germinated its seed easily(a few weeks) on peat/sand mix.Mine have also divided naturally,which i cut up with a sharpe knife,because the roots are very long and thick on this species.

Daniel O. Posted November 3, 2008 Author Report Share Posted November 3, 2008 (edited) Hi Ada, you should be succesfull with your pollinationi hope you are right. Last year i tried to self pollinate another clone and it has not worked. But i also hope to cross pollinate some flowers later in the year, this should work in every case.

Vincent Limbourg Posted December 13, 2008 Report Share Posted December 13, 2008 Good news Dani! Last week I noticed a flower on my P. lutea! I can't wait to see the flower! As soon as the flower opens, I'll post some pics. Quote Link to comment Share on other sites More sharing options...
Carlos Rohrbacher Posted December 13, 2008 Report Share Posted December 13, 2008 Hi Dani. P. lutea is very different. I loved this cute yelow flower, which the size of the plant and flower? Regards. Carlos. Quote Link to comment Share on other sites More sharing options...
Daniel O. Posted December 15, 2008 Author Report Share Posted December 15, 2008 (edited) Vincent, really great news. There is some kind of variation in the form of the rosette and the flower, my second plant has had a much bigger flower, about 3,5 cm in diameter. Of course i´m looking forward to see your flower. Carlos, yes, in comparison to P. ionantha and others it´s really very different, it´s also getting much bigger, but for sure there are also excisting smaller clones. As i mentioned, the last flower was about 3,5 cm (the first plant has had a flower with about 3cm in diameter) in diameter (much bigger than P. ionantha), the plant itself is about 13-14cm in diameter, really a monster. And this yellow colour is really very unique , so fare i know there are not excisting any other species with such a colour. Best regards, Dani Edited December 15, 2008 by Daniel O.

Carlos Rohrbacher Posted December 15, 2008 Report Share Posted December 15, 2008 (edited) Thanks (for P. lutea and P. ionantha informations) Dani, good growing! Edited December 15, 2008 by Carlos Rohrbacher Quote Link to comment Share on other sites More sharing options...
Vincent Limbourg Posted December 16, 2008 Report Share Posted December 16, 2008 Is there any chance to self pollinate the flower, or is that impossible? Otherwise I'll have to look after some pollen... Quote Link to comment Share on other sites More sharing options...
Daniel O. Posted December 17, 2008 Author Report Share Posted December 17, 2008 (edited) Hi Vincent, normally it´s possible, but i´ve heard that cross pollination between two different plants produces a larger amount of seed and the viability/germination rate drastically increases. But last year my self pollinating attempt was not successful with my other clones, this year the first seed capsule has swollen, but inside was no seed. The second one has swollen a lot (about 7mm now) and from outside there is something dark visible, so i hope i was successful. To reach the pollen of P. ionantha is a little bit more difficult because of the smaller size of the flower. Best regards, Dani Edited December 17, 2008 by Daniel O.
