Tropaeolum

[Jean-Patrick AGIER]

Hi Rogan ,
I think you've been given the right advice. The tubers must be kept a little dry during their dormant spell. But not completely. I personnally keep the pots  protected from direct sun but water sparingly from time to time or just spray the surface. By now I have 6 or 7 plants shooting. And Tropaeolum Pentaphyllum is growing quickly. We are at the gate of Autumn here and it will be time to expose the pots to more light.
You must separate Tropaeolum and Sandersonia. I've repotted-and checked-all my tubers late July as soon as they had died back. But Tropaeolum Rhomboideum had already begun to shoot underground (!!! ) and it probably won't like having been disturbed ...
Be confident
Regards

Jean-Patrick, I've done the same thing myself scratching around under the soil. Can't resist taking a look to see how they've multiplied during the season.

[Lesley Cox]

Scratching around doesn't always help as some species travel deep and leave their tubers on the bottom of the pot.

You're right Lesley - that's why I empty mine out into a tray and sift through, collect all the tubers, get a good look at what's happening then repot them into fresh media, ready for the next season.

Hi

I also keep my tubers fairly dry over the summer and repot around this time of year. I thought that you might like to see my "buried treasure".  

This year I have twelve species (2 sub-species of T. hookerianum), two named hybrids (x tenuirostre and nubigenum x pollyphyllum ) and a number of pots of unnamed hybrids largely based on R. Wilson's crosses.

I also sow seeds around this time of year and if anyone is interested in any of the following I could supply a few seeds to a few people.

T. beuthii
T. brachyceras
T. sessilifolium
T. Hybrids

I also have some seeds of T. smithii which I initially thought that I might offer to growers in the southern hemisphere as their summer is approaching. I don't have many seeds at the moment but the plant is still flowering and I would hope to have more available  later in the year for spring sowing in the north. One warning -  I have had very poor germination of this plant.

If anyone is interested please email me with your address and I will send you what I can.

Hi there,

I oversummer T. tricolor in its pots outside under a glass roof, and the shoots already appeared - everything's a little early this year (Canarina canariensis is almost flowering!).
The other species are still sleeping...

[mickeymuc]

I have some more pics of T. argentinum, which has grown very large (more than 4 m !). After it had grown to full size, all tips were crowded with flowers - after all it is a very special but (to my opinion) pretty plant, I had it growing together with Dicentra scandens and Clematis viticella, which was a pretty combination. It has also produced lots of seeds.

Best regards from Munich/Germany,

Michael

Lovely combinations Michael, well planted

Steven, your "buried treasure" is very impressive!  Looking forward to seeing it revealed

Absolutely, I agree with Brian, they look lovely - I've always liked T but really only been acquainted with the common red on growing over Yew.

Steven you simply MUST post lots of pictures of your collection as they grow and bloom. I'm really looking forward to seeing them.
Impressive collection.

Thanks Brian & Robin !

If you're interested im some argentinum seeds tell me, I have lots of them already and many are still ripening!

Kind regards from Munich,

Michael

Hi Michael,
Lovely photos indeed. The close-up of the flowers is really stunning. I have one question: how many seeds did you sow? and how many seeds did germinate? I personnally had one plant out of approximately 10 seeds sown. Another one has just raised ( several months after the first one ). So the germination rate seems quite low.
Any contribution about this?
Regards
Jean-Patrick

Hi, everyone.

I'm a Japanese Tropaeolum lover.
I found this forum a few months ago, but because of my poor English  I hesitated to comment.
But now I do want to participate in your conversations. I'm writing this with help of internet translation site.

Steven, many thanks for introducing my web site here and there.
Your site is wonderful. There are some species I've never seen flowers...moritzianum,smithii,speciosum,etc.
Someday I want to see their flowers.

Michael, your argentinum photos are wonderful. I sowed some seeds last season but never germinated.
So I have the same question as Jean-Patrick. How about the germination rate? And is there possibility that
they germinate after 1 season or so? How about to the germination temperature? I'd like to know your experience.

The new season begins in September in Japan.
I contribute these photos in commemoration of the first participation. These are hybrid azureum appeared last season.

Kind regards from Japan,

DORA
