Codonopsis
Carolyn:
Veronique,
Have you seen the website woodlandsplants.co.uk? Bob and Ann hold the national collection of codonopsis and have some very useful information on the website.
I have some problems growing codonopsis too - the biggest problem this year is the slugs eating the seedlings.
Véronique Macrelle:
Thank you Carolyne, I notice it has been redone. Unfortunately now the Brexit is preventing me from ordering it...
I've tackled the convovulacea group at least 5 times (starting from seeds), it's so small at first.
The small tubers often have trouble withstanding the winter, although now I've got a few plants from the previous year in bud.
I'm also starting to get the hang of sowing, and I've got bigger plants from seed this year (Codonopsis grey-wilsonii)
I can't wait to see that first flower! below Codonopsis forrestii:this is a plant from seed in its 3rd season. last year it finished growing before flowering...
I'm keeping them in the greenhouse for the time being, as my attempts to put them outside have been frustrated by slugs.
I also found a pot in which 2 tubers had lain dormant: healthy, but not growing; curious.
Véronique Macrelle:
That's it!
I finally see a flower of this very desirable Codonopsis.
While the label says Codonopsis forrestii, the purple ring seems to indicate a Codonopsis grey-wilsonii, according to Yuan-Hong's book on codo. The fluffy details of the flower are incredible: it's always a joy for me to use technology to observe plant textures up close.
I wonder if, with the best cultivation, you can get a flower the year you sow it...
Véronique Macrelle:
here is another flowering from the convolvulacea group (or Pseudocodon).
the seed label indicates Codonopsis forrestii: flower + blue, almost twice as small, the central ring is very dark (the camera changes the colour) and directly around the receptacle.
it also seems to close at night.
Véronique Macrelle:
my third plant in this group, labelled Codonopsis vinciflora is preparing a flower bud. This time, of course, it's a different species because the flower bud is different: the calyx is not fused around the corolla in bud
the leaves are also more toothed. Another week or 2 to see the flower in full bloom. Let's hope it doesn't wait until I'm away on holiday!
