Can anyone tell me what this is, please?

Tropaeolum adpressum?
-
I think you're right, Matt - thanks!!
-
It looks to be a lovely plant Maggi. Is there a reasonable quantity of bloom to foliage?
-
And is there a reasonable quantity of seed set to the bloom?
;D
cheers

No idea, Lesley, fermi - it was a someone posing the question on Twitter and I was puzzled.
-
Oh well, the possibilities were hopeful while they lasted. :(

Hello,
This tropaeolum picture depicts a species from the serrato-ciliata section which is very confuse because the plants of this section are are very close to one another and are not currently in cultivation. And of course because their description is only taxonomic to this day. No one can tell what species it might correspond to by seing only 2 flowers and no leaves. The only reference we can rely upon is the taxonomic work by Sparre & Andersson ( which is a bit "technical" ).
The flowers doesn't seem to be pilose and the spur is red with a green apex. I think it could match with tropaeolum deckerianum. But this is only a possibility...
Maybe Graham could tell us more?

Tropaolum huigrense is considered a weed in Lyon's glass house.
The plant is self fertile and germinates quite easily here.
It can produce hundreds of seeds.
Flowers are quite small compared to the foliage.

Hi JP- I saw that you have what I think is the same photo , as this perhaps adpressum on your site ( flikr, maybe?) with the Tropaeolum deckerianum possibility. I think the flowers in the query photo are also not fully developed , so that is a further confusion ,eh?
-
Tropaeolum tricolor is making a good show outside - this plant is in a container against a south-facing wall, kept outside all year round. In the glasshouse (just frost-free) Tropaeolum azureum is opening its very welcome flowers too.

Hi,
Here are a few pictures of young 2015 seedlings.
Tr Moritzianum
Tr Fintelmannii ssp olmosense
Tr Argentinum

In typical Tropaeolum form, this seed of Trop. peltophorum germinated after 2 and a half years in the pot, and practically forgotten by me.
-
Two Tr INCISUM seedlings from the AGS seed exchange 2014 / 2015.
Curiously one of them has a double shoot.

The conjunction of a sudden heatwave and aphids proliferation has prematurely put an end to growth and flowering of most of my Tropaeolum which I grow on my balcony. Some plants even didn't flower...
Here are 2 pics of Tr BRACHYCERAS. One plant curiously seemed not fertile ( no pollen ).
Sadly the 2 plants have withered now.

I can't resist in posting ( again ) some pictures of my tropaeolum sessilifolium.
This plant grows and flowers reliably in a container on my balcony.
It mingles with other Andean species which unfortunately don't find the optimum conditions for blooming.

...some more pictures of tropaeolum sessilifolium
JP

Such a pretty thing, Jean-Patrick, who could resist more photos?
-
Thank you Maggi!
So here are some more...

It's fun when I realise how much one flower reminds me of another I've just seen in the pages of the forum..... this happened with Robert's pictures of Mimulus aurantiacus var. grandiflorus in his thread from California .... follow the link ...

Hi
I thought that you might like to see a couple of pictures of T. leptophyllum which has just come into flower. This came from a tuber I bought from Rareplants last autumn.

Hello again
I thought I would post pictures of a hybrid that is still in flower.
[attachthumb=1]
[attachthumb=2]
Yes I did say "a" hybrid. The rose colour fades to the lilac.
[attachthumb=3]
Rather pretty and quite interesting.
Steven
-
I'm very taken with the colour of Trop. leptophyllum - and the changing shades of your hybrid are very pretty - I'd have been less surprised if the change had gone from lilac to rose!

Hi,
Tropaeolum polyphyllum doesn't do well on my balcony...
The plant at Lyon BG has been re-established in the alpine garden after its South American part have been dismantled.
A lot of pouzzolane have been added and the plant seemed to like it.
This species is absolutely stunning!
JP
-
Hi Jean-Patrick,
Pouzzolane appears to be some sort of scoria or other volcanic material - was it dug in or just used on the surface of the bed? The Tropaeolum seems to be enjoying it!
cheers

I'm certain my T. polyphyllum would have flowered for the first time last year but a bird or a possum nipped off the shoot as it was expanding. I was furious. This year it has an aviary wire cage over it. 8) Your pictures are beautiful JP.

The Royal Botanic Garden in Edinburgh posted these photos on facebook of Tropaeolum polyphyllum expanding over the Rock Garden in RBGE - it looks to have ambitions to take over Edinburgh!
First, a close-up of the golden flowers
[attachimg=1]
and here is some of the spread!

Fermi,
Yes pouzzolane has been added to the new soil of the alpine garden ( medium sized ).The Royal Botanic Garden in Edinburgh posted these photos on facebook of Tropaeolum polyphyllum expanding over the Rock Garden in RBGE - it looks to have ambitions to take over Edinburgh!

Maggi,
This picture is really fantastic!!!

Maggi that's fantastic! I would love to see that in person.

Derry Watkins has made a facebook post about T. polyphyllum - I quote it here and give the link to her website for the seeds :
"Tropaeolum polyphyllum is an exquisitely beautiful hardy perennial Nasturtium from Chile. The pale blue grey leaves meticulously arranged all along long trailing stems make it worth growing for foliage alone. Pretty lemon yellow flowers erupt from the tip of each stem in June and July. By August it has become dormant and you will see no more of it until next April. It is very rarely offered for sale but has taken over about a square meter of my gravel garden
For years I tried to collect the seeds of it. I could see them form (they look like overgrown green peas) but they seemed to disappear before they ripened. Then last summer I noticed that ordinary Nasturtium seeds fall off while still green and dry on the ground into the dry hard nasturtium seeds we know. So i tried sowing the big green Tropaeolum polyphyllum seeds and lo and behold they germinated a few months later
The internet says to sow it in spring from fresh seed, but as it sets seed in July that seems an utter impossibility. Really fresh seed seems to germinate fairly quickly. According to the internet, older seed which has dried will need vernalization , that is a damp cold period, possibly quite prolonged, sometimes up to 2 years if left outside to the vagaries of the weather.
When the seed does germinate, grow them in deep pots. The tubers like to pull themselves down very deep, so it is best to plant the tuber after it goes dormant in midsummer and you can bury it a foot or so down. It will eventually pull itself down 2 or 3 feet!. It needs very good drainage and plenty of sun. Once it is happy it is perfectly hardy and can become rampant, but as both the leavers and flowers are beautiful it is not a problem
And i now have nice fat green seeds for sale!"

I bought 2 packets of seeds from Special plants today at the Chenies Plant Fair. Between them they had 5 green seed and 5/6 shrivelled seed. I have sown them separately (green in 1 pot, others in another) in deep pots and put them in shade on the north side of the house. It was 24C today so not so cool but we will see what happens.
I have grown this plant before, many years ago, in chimney pots if I recall correctly, and kept it for several years but never started from seed. I may plunge these pots inside larger deep 3 litre pots before winter. See later.

Can I draw the attention of the tropaeolum enthusiasts of this forum on the Fundacion RA Philippi web site which has been updated and completely redisigned.
The tropaeolum pages offer a lot of brand new pictures and also takes account of the new classification for the 2 Tr LEPTOPHYLLUM subspecies according to a very interesting recent publication ( in Gayana botanica ):
-Tr LEPTOPHYLLUM ssp leptophyllum is now Tr MYRIOPHYLLUM
-Tr LEPTOPHYLLUM ssp gracile is now Tr LEPTOPHYLLUM ( or Tr GRACILE )
fundacionphilippi.cl/search/node/tropaeolum
Adding to this the Plant World website offers seeds of one of them: Tr GRACILE

Thanks Emiko and Jean-Patrick for your fascinating article on tropaeolum hybrids in the January 2016 issue of The Rock Garden (vol. 136, part 1).

I echo those thanks - I'm looking forward to reading it.
