Véronique Macrelle:
Aconitum austroyunnanense qui fleurit tardivement. je ne pourrais pas envoyer ses graines pour l'échange.
 je ne la trouve pas vraiment grimpante, ses tiges s'allongent mais restent assez raides  par contre elle fleurit sur l'aisselle des feuilles. Mais c'est seulement  sa deuxième année au jardin, et elle est déjà bien plus jolie que l'année dernière.

Véronique Macrelle:
semées ce printemps et fleurissant dans la serre maintenant:

-Dactylocapnos scandens :  est-ce que cette plante peut survivre d'une année sur l'autre ? fait-elle un tubercule, un rhizome?
l'année dernière mon semis s'est développé beaucoup sans fleurir et a péri durant l'hiver. heureusement une graine a germé à nouveau. Mais je crois qu'il faut une pollinisation croisée pour obtenir des graines. Je vais donc sans doute la perdre. :(. en attendant , j'adore!

-Ipomoea alba une première floraison tardive également. j'ai plusieurs plantes en pots et plantées, mais le semis n'est pas si facile: j'espère qu'elle reviendra de souche  l'année prochaine.

Vinny 123:
I have always found Dactylocapnos scandens to be short-lived outdoors. In most years it will flower profusely and make lots of seed (I suspect that it is fully self-fertile). It is perhaps borderline hardy - frosts of lower than -2C or so hit it hard (guessing at precise temperature).
In a good year it might make 2m up into a tree and be cut back by the first frost or close to freezing.

I have never tried a heavy mulch over them for the winter. I suspect the fleshy nature of the underground parts would require a dry mulch rather than one left open to the rain. (I use a ring of small wire netting, filled with fallen leaves and place a pane of glass over that. That works here for Imapatiens tinctoria which will otherwise not survive a winter in the ground here.)

The roots are like very long (maybe to 30cm?), thin (to maybe 15mm) Dahlia tubers, mostly spreading rather than predominantly vertical in the ground. They are fleshy roots rather than a true tuber, IMO.

Has the debate over scandens v. macrocapnos been settled?

Véronique Macrelle:
Thanks, I'll try to winterise it better.

here, I don't know which plant it is exactly, I find it more golden than another plant that I had in the ground a few years ago and which was self-sterile, and without the darker lip.

I hope to get some seeds from it...

Mariette:
The slugs have destroyed the larger part of the plants in my garden, but there are some survivours.

Ipomoea alba climbed 6 m this year - unfortunately too high to enjoy the beautiful scent.



Another ipomoea - I like the ornamental leaves of I. pubescens.



One of the darker flowering Cyclamen hederifolium in my garden.



Crocus gilanicus



A colchicum from Georgia which self-seeds in my garden, probably Colchicum woronowii.
