Pinguicula corsica

[fredg]

This greenhouse pot of Pinguicula corsica has been in flower for about a fortnight. The outside tray is still yet to open flowers.

Hi Fred,

I saw this post in the Pinguicula section, and I was curious how long you've been growing P. corsica? I lost a bunch of them this winter (which has been crazy warm) and was hoping you may have some techniques that are working well for you. I also have lots of P. grandiflora and few other temperate butterworts.

Bonjour

it is very very easier to grow P.corsica specially the var pallidula , I have this specie and the 'type' since several year without problem.

what other temperate pinguicula have you ?

I keep it just the same as P. grandiflora Jeff, both inside an unheated greenhouse and outside in a shelf unit with the front open.

Thank-you for the responses. I think I narrowed down the problem to them being too wet. I had some trays flood, and our winter was very warm. Those two things together made them rot. It seems that P. grandiflora can tolerate being much wetter than P. corsica.

Have either of you grown these plant in an alkaline media? I've started adding dolomite lime to the media (peat/sand/perlite), and the plant don't look any different in the alkaline media, but they seem to hold up better over time.

Likely the plants will be happier with pH above 7. Grandiflora can grow in peaty soils, while most species prefer sandier or rockier substrate.

Not tried that Jeff, they were doing just fine in peat/granite grit I didn't see the point of playing with the medium.

Bonjour

I have find grandiflora subsp grandiflora ' in situ' in undifferentiated backgrounds, but mostly on peaty or limestone areas
