Dividing Jeffersonia dubia

[ronm]

Thanks Mark. A slip is what it was   . Sorry Koko if I misled you. I meant to type " Jeffersonia dubia ( both blue and white forms )" but diphylla slipped in!
I've edited my original post.

I wonders about somthing...i got some Jeffersonia dubia 'alba' flowering here for the first time...really nice but the flowers are atleast twice as big as normal blue-ish one.....anyone with the same experience?....Jonny

[Maggi Young]

Jonny, I think that Cyril Lafong exhibits a plant of  the alba form that has great big flowers.... I will see what photos might be in the Forum.

 Yes, found photos of his plant here : http://www.srgc.org.uk/shows/forrest2010/edinburgh.pdf  .. you will see they are superb big flowers. Perhaps always good feature of the white form?

[Jonny_SE]

Thanks Maggie   Thats exactly the size i got...does anyone got the alba in small flowers i would gladly trade one.....Jonny

[Maggi Young]

Yes, it seems, looking around the forum pix that the alba form seen is usually one with fine large flowers.....

Well, well, well, looks like Jeffersonia dubia alba certainly exists on the other side of the ocean and it is just BEAUTIFUL!!

Mark, we just will have to keep drooling, lusting and looking.

Thank you everyone for the information.

Maggi, you are just amazing.  Much quicker and accurate than me googling!

  I'd have been faster but I stopped for some cake! 

[KK-Ann Arbor]

Jonny, 
That will be great.  Thank you.

Maggi,
I hope that was a tasty one.  Of course I understand that there are priorities.

It was delicious.... soft sponge, jam and cream filling, marzipan coating and half chocolate covered 
bouht for very little money from a shop- no effort involved at all  to enjoy it 

Thank you Koko, for your understanding... such thoughtfulness from Forumists is much appreciated.

Jeffersonia dubia has always been one of my most favourite plants, way back from first seeing a picture of it in Anna Griffiths book on Alpines. But I never realised that it could vary like those pictures of Mark's; really fascinating. Does it compete with the cake though? We don't seem to have shops like that round here!

Jeffersonia dubia is one of those plants that I cannot sow but which occasionally sows itself. This probably means that the seed is very ephemerical and needs an autumn-winter-spriong sequence. I find it difficult to establish. It sulks in the beginning but after a few years it is going strong.

I'm re-activating this thread to post a link to the NARGS Forum, where Rick has given an update on his attempts to divide the glorious plant he showed here last year :

I have two forms, light and dark flowered, with flowering seedlings around them in the open ground. I know that the advice is to prick seedlings out 'as soon as they're big enough to handle'. What about seedlings of 2-3 years old?

I want to distribute the dark form, ideally by potting up in May. Is that feasable?

[TheOnionMan]

I had so many flats of Jeffersonia dubia seedlings that I didn't get a chance to plant them all out, even after I gave a couple flats away for our local NARGS chapter plant auction.  This is a second year flat of seedlings; I'm hoping that they are as easy to separate out and plant as 1st year seedlings; they're still small so I don't think there will be any difficulty.  The roots on Jeffersonia grow into a wide mass, so if seed-grown plants get much older than 2-3 yrs, I imagine they become more difficult to separate without disturbing them.
