my last plant to flower this year from the
Pseudocodon
group:
Codonopsis vinciflora
or
Pseudocodon vinciflorum
. this is a first flowering for this species.
this plant was very slow to get going in spring, but is now perhaps showing more vigour. its flower buds do not have the sepals fused around the corolla
the flower stalks are thicker and longer, which means that the flower stretches upwards. there are no velvety hairs in the centre and no violet rings. it is a more intense violet-blue.

perhaps it's interesting to put the 3 Pseudocodon side by side...
although I'm not really sure that the second and third (perhaps grey-wilsonii, after all) are really different.

Véronique,
The Pseudocodon are interesting and beautiful. The inflorescences are quite different from most codonopsis.

I’ve just been alerted to these posts by a friend and am only too happy to help another Codonopsis grower if I can. Firstly please refer to
www.codonopsisplants.co.uk
where, as Carolyn says, there is lots of helpful information on growing and identifying them.
Specifically, C.gracilis should be treated as a tender biennial and always collect seed if you can to ensure its survival. It is a wonderful plant and worth the effort.
You may be able to maintain C.kawakamii in the garden but here in the UK I also treat that as tender, although perennial.
The Pseudocodons can be a little tricky but there are four that are regularly grown and, once you know them, you’re well on the way. P.vinciflorus has smaller flowers with the distinctive calyx lobes as you have noted. It has the best colour of all of them. P.convolulaceus ssp forrestii is usually the last to flower with large paler flowers and a very dark centre. P.grey-wilsonii has a distinctive purple ring on the blue flower and the pure white form, P.grey-wilsonii Himal Snow, rarely has a purple ring. Certainly I’ve never seen one so your pale form is very interesting.
The seedlings of Cc ovata, cardiophylla and obtusa may flower next year and have almost certainly been grown from seed I sent in last year.
If you’d like to look at the website you can always contact me through that. I look forward to hearing from you further and good luck.

Hello Bob,
delighted to chat with you...
I've looked at your site through and through
it's superb.
Thank you also for sending your seeds to the CGRS last year: I really enjoyed it.
and for answering my questions.
the pale form of Pseudocodon is light blue, not white.
I have another (charming) form of probably
Pseudocodon vinciflora
(sepal not adhering to the button), even bluer than the first, smaller, 2 cm wide and above all with a more campanulate, less flattened shape: which gives it a tonic appearance. Its leaves are almost round).
I photographed it next to the paler Pseudocodon ()que vous estimez de quelle espèce ou sous-espèce?

We’ve had a completely pale blue form of P.grey-wilsonii and tentatively named it Blue Ice but still waiting to see if it comes true from seed. Your pale one with purple ring is very nice though. Kit Grey-Wilson has told me that he’s seen completely white ones with a purple ring in the wild but not in cultivation. Like all Codonopsis and Pseudocodon, P.vinciflorus can be variable but all are lovely.
Don’t forget, you can always email me as I don’t always check the forum.

Most of my
Codonopsis grey-wilsonii
seedlings have been resting, so I looked at the tubers produced in one of the more developed pots. I think I've done better than in other years: the tubers are bigger.

in August, we had a peak of 42°C, which fortunately did not last long.
many
Codonopsis
unfortunately went into sudden dormancy: all the
Pseudocodon, C.subscaposa, ovata, cardiophylla, obtusa, rotundifolia, gracilis...
However, some individuals have resisted, and remained beautiful and green: these are the ones that are entangled in other plants:
C. lanceolata
entwined with an
Ipomaea, C. rotundifolia
entwined with a
Delphinium caucasicum
, protected by its broad leaves and, I'm delighted to say,
C. subscaposa
, which remains green and thriving, shaded by the wiry foliage of the annual
Gilia tricolor
.
I think the association has done them a favour by providing more freshness at a critical moment, a question of atmosphere.
I'm posting photos of the large pot containing
Gilia
+
Codonopsis subscaposa
(still quite small). Then a photo of the state of
C. subscaposa
now, in full form and continuing to grow in the centre of the pot.

while some
Codonopsis
are completing their vegetative cycle, others are starting to flower, such as
Codonopsis lanceolata
. as it's a bit late, i don't think i'll have any mature seeds of this species for the exchange. However, I already know that I will be sending
kawakami
and
pilosula
this year..
