bigphil1984 Posted August 21, 2017 Report Share Posted August 21, 2017 Hi everyone, I got my pinguicula grandiflora a few days ago and was wondering why the leaves curl at the edges? Sent from my SM-A300FU using Tapatalk Quote Link to comment Share on other sites More sharing options...
Gaz Posted August 21, 2017 Report Share Posted August 21, 2017 I don't suppose we can know for sure but the theory that curled up edges prevent excess dew from dripping of the leaf is as good as any. Quote Link to comment Share on other sites More sharing options...

I thought it was maybe too cold or something, with the weather been up and down! Do you think it will flower?Sent from my SM-A300FU using Tapatalk Quote Link to comment Share on other sites More sharing options...
Gaz Posted August 21, 2017 Report Share Posted August 21, 2017 I'd be surprised if it didn't but it should be going dormant any time now, will form a hibernacula then rest until late Winter. Once it wakes up it should flower soon afterwards. Quote Link to comment Share on other sites More sharing options...

manders Posted August 21, 2017 Report Share Posted August 21, 2017 Im actually convinced my grandifloras keep growing more hibernacula all winter, little ones around the edges. Quote Link to comment Share on other sites More sharing options...
Gaz Posted August 21, 2017 Report Share Posted August 21, 2017 These plants are from cold temperate climates and have to be dormant when the frosts arrive (Ping leaves are very soft). If you're thinking of Sarrs, vfts etc, they are tougher plants and from warm temperate climates which don't usually get as cold. Quote Link to comment Share on other sites More sharing options...

Mine do the same, end up with loads of them. Quote Link to comment Share on other sites More sharing options...

Sent from my SM-A300FU using Tapatalk Yes, usually you get lots of them around grandifloras, worth spreading them out a bit in early spring or theyll get smothered by the main plant.

carambola Posted August 21, 2017 Report Share Posted August 21, 2017 I read something once that it keeps the caught gnats from walking onto the non-sticky side of the leaf to escape. It does seem like they can trawl across the whole leaf, but still end up stuck at the edges. That said, if they walk to the other side, they can just crawl onto the bottom of the next leaf, so I'm not sure how much weight can be given to this explanation.

blaasjeskruid18 Posted February 6, 2018 Report Share Posted February 6, 2018 Very late, but if I remember correctly they do it to prevent prey from being flushed away when it rains 1 Quote Link to comment Share on other sites More sharing options...
manders Posted February 7, 2018 Report Share Posted February 7, 2018 That seems unlikely, anything but the lightest rain would wash any ping leaf clean, ragardless of the raised edges. I think more likely it stops the digestive juices overflowing the leaf and wasting the nutrients (in dry weather). 1 Quote Link to comment Share on other sites More sharing options...
blaasjeskruid18 Posted February 13, 2018 Report Share Posted February 13, 2018 (edited) I can't really remember where I read that, but something comparable was written in The Savage Garden: ''Some species of pings also have the power of movement. This is most often seen in species from temperate climates; it is almost entirely lacking in tropical forms. Over a period of a day or so, after the capture of substantial-size prey, the margins of the leaf, already upturned, may curve inward or over the precious food. This has nothing to do with capture but is believed to be helpful in preventing the digestive fluids from drooling off the leaf. Another possible explanation is that it helps prevent the victims from being washed away by the rain. Many butterworts can even ''dish'' their leaves under prey, giving their juices a convenient place to pool.'' http://www.sarracenia.com/faq/faq5440.html gives another explanation though: ''For the most part, there is no motion in the leaves. However, the leaves do often dimple slightly underneath captured prey, possibly to create a little pool of fluid to aid in digestion. Also, and especially on temperate species, the leaves roll up on the edges. A few theories have been proposed to explain this, and perhaps two of the most intriguing are that the leaves may be curling up to keep marauding ants from stealing the captured prey, or to create a kind of tubelike structure along the edges of the leaves so that capillary action spreads the nutrient-rich bug juices over a larger amount of leaf area, enhancing nutrient absorption.'' I guess science still isn't sure why they do this Edited February 13, 2018 by blaasjeskruid18 1 Quote Link to comment Share on other sites More sharing options...
Argo88 Posted February 14, 2018 Report Share Posted February 14, 2018 I’ve observed a little motion in youngest plants of p. Gigantea leaves too, when the preys are quite big for those leaves... the leaf curl a little around the bug and, if you see it in the night with the help of a light, you can see a very big amount of liquid around the prey.. it seems to be wet... but after that the leaf stay “curled” and don’t return to the original shape, as my temperates pinguiculas do Quote Link to comment Share on other sites More sharing options...

ham Posted April 5, 2018 Report Share Posted April 5, 2018 ive read an article before and it is something about preventing the digestive dews from dripping away from the leaves Quote Link to comment Share on other sites More sharing options...
