Pinguicula filifolia - another odd Pinguicula

Hi epbb,

Unfortunately, they died in the heat wave during the hot season.
Sorry about that. For an hot tropic species that's strange to die during a heat wave.

The day-night temperature difference in Singapore is very little compared to temperate countries during the summer season. Also, the humidity is very high at above 85%RH. We can't grow a large number of African sundews and Mexican pings.

Yeah, those are all highland plants. All that heat sure does restrict what you can grow...

Bonjour
in my opinion, the fact that these Mexican ping are mountain plant is not the problem, but the seasonality of climate, with a dry period from November to May and a rainy period (April-May) in June October.

average temperature in isothermal January: 19-21 ° C July isotherm for :21-27 ° c

I thought P. filifolia was a hot tropical plant? It wouldn't have the same requirements as a Mexican Ping, not haivng to deal with the extreme seasonal changes the Mexis do. However, most species found on Cuba are a bit more difficult to grow, maybe it was something besides temperature that killed it.

[Dave Evans]

Well, from what I've seen of P. pumila, it doesn't like heat much! Yet cannot handle frost without heavy mulching. So, like other small butterworts, it probably like locations with airflow, but rather dappled or shaded areas with tall grasses about the plants providing niches along the ground where the P. pumila could grow. So it seem to be a balance of bright, but very diffused light, high humidity, sandy soil--a buffered area somewhat protected from the daily temperature extremes.

Pinguicula filifolia is from hot lowlands in Cuba, see this recent paper on its ecology and morphology: www.sciencedirect.com/science/article/pii/S0367253012001429

I am surprised that this species isn't more widespread in cultivation and that there aren't any hybrids (that I could find).

I would love to have it on my Ping Wall: www.cpukforum.com/forum/index.php?showtopic=17560&st=120


Merry Xmas to all!

I think most pings are adapted to lower heat.
I've seen P. pumilia in the wild, and although the day I saw it on was well over 100 farenheight, these pings were growing in dark places, away from the sarracenia and drosera basking in the full sun.
Where these pings were it was more like 85-95 farenheight.

Maybe P. filifolia also lives in slight shade?

Hi there
In Cuba P.filifolia is growing in sand in full full sun light near sea level, so there is always high humidity but also breeze (which is important to keep the fungus away).
I thing that is also the key to keep this beauty happy.
