Pinguicula macroceras Breeding

I have been growing a line of Pinguicula macroceras from here in California for a number of generations from seed to seed. Strangely, I seem to have developed this tiny strain.

very nice

can we see the plant from the front, to see the throat

You sure you didn't cross that with Pinguicula pygmaea :biggrin-new:

More photos. The original parent I started from seed in 2010 filled the pot, 2 ½ inches in diameter.

I tried; didn't work;)
That's cool, thanks for sharing!
Neat looking Ping.

let it grow up
how old are the little ones?

I sowed the seed of the latest one to flower in January last year. It flowered the first time in October. 9 months from seed to flower! It flowered again 5 months later after 2 months dormancy. Dream for the future: Maybe with more breeding we can eliminate dormancy and make the plant faster growing.

it is a temperate then for me , its need to go through a period of dormancy with a hibernacle.

Right. When hibernaclae are fully formed I bag mine and put them in the fridge for 2 months minimum. At least I don’t need to water them for that period.

I should also mention: P. macroceras and P. vulgaris do hybridize and the hybrid is perfectly fertile. I made this hybrid years ago. The first generation hybrids grew vigorously. However, following generations grew increasingly weak. I don’t know if this weakness was a result of inbreeding depression or the hybridization.

here I always leave them outside all the year , during this period they are always damp (by capillarity)
their hibernacula is formed in August the rosette develops in March,here it is the first temperate that is growing

have you a picture to this hybrid ?
do you know if the 2 species are present on the same area 'in situ' , may be just in alaska where both species are present?

Sorry, I have no pictures of the hybrid I made. I wonder if anyone else has done it.

A new generation. I performed microsurgery and self pollinated this flower this morning. Very difficult with such small size. I believe its small size and upturned flower are genetic defects caused by inbreeding depression. I’m hoping I might likewise get a plant in a future generation which does not need to go through a dormancy in order to flower.

I'm impressed that you can keep this species going. I've had no luck with P. vulgaris and I would expect the same with P. macroceras though strangely, P. grandiflora grows easily for me.

Line from the movie Titanic: “I will never let go”:

It’s not making seed; no seed capsule forming. Now that it seems I have ruined my California plant by inbreeding I might as well cross it with another vulgaris variety to restore its vigor.

A study about breeding and how that larger flower spur of macroceras serves to please certain pollinators would be great. @bluemax, have you had any critters pollinate your grandiflora? I’ve read that Hummingbirds pollinate Mexican pings. I’d like to see that.

I confess that I haven't paid any attention to pollinators in my P. grandiflora, but that is an interesting question. The flowers on these species all are showy enough that they should draw in various species, I would think. The hummingbirds are very much present in my yard - I will have to keep to an eye on the flowers when they bloom next year and see if they have any interest in them.
