I have two of these plants, one from white seed and one from pink.
Have just seen each one has a bud and both appear to be yellow.
I'd love to know what they are.
-
Looks very like a plant I am growing as Potentilla hyparctica, Helen.
It is quite similar to Potentilla crantzii but it's furry all over.
Not that I am sure my plant is correctly named, you understand :-X
-
Maggi, you're a sweetheart.
After googling I think you are right.
-
Helen, I've never looked for seed on my Potentilla nitida rubra (I know, I know, I'm a bad person :-[ ) but I'll check it this season to seed if I see any for you.
It's had a couple of flowers already...in fact I'll go look now.....
edit.... well, there may be seeds forming.... I'll keep watch!
-
Maggi, that would be fantastic, thanks muchly.
The first bud is half open now and bright yellow.
One thing's for sure, misnamed seeds are much easier to live with when you get something lovely from them.
-
Here's a couple of pics of P nitida rubra from my garden a couple of years ago for comparison, Helen.
I've never knowingly had seed on mine but I'll also check this year. Are potentillas self compatible or do we need two plants - I've never really thought about it?
-
Wow, Dave, thanks for the pics.
Your plant/s are truly beautiful.
Sorry I can't help with how potentillas make seed.
-
Crikey David, that's a cracker! I'm impressed :)
-
Helen,
Before Maggi suggested P.hypartica, I was going to suggest P. pulvinaris ssp pulvinaris.
I took the liberty of copying your photo and comparing it with mine. Yours on the left, mine on the right.
They look very similar but then so do lots of Potentillas. Mine came from Arrowhead Alpines but I guess they grew it from seed anyway.

Alan, as I said, I am by no means sure my plant is correctly named... will need to research P. pulvinaris ssp pulvinaris to see how mine compares.
Thanks!
-
Cor David - has your plant not read the books which say it is supposed to be shy flowering?
-
Alan, they do look very much alike, do you have any pics of the flower?
Was hoping my flower would be open today but is raining at the moment.
-
Sorry Helen,
Mine hasn't flowered yet but the flowers are definitely yellow. I'll send you some photos if and when it does flower this year...it's a first year plant.
Alan
-
Terrible pictures... the petals are falling/being blown about in the breeze.... hope this helps a bit, Helen....
-
Maggi, thanks for the pics, these are your P.hypartica?
When do the trailing stems develop, after the flower opens?
Mine is not co-operating at the moment, this is how it looks at the moment.
-
Yes that's what I think is hypartica ::)
The flowering stemsstart out quite short, about five cms (2inches) but then they quite quickly extend to around 10 to 12 cms (up to 4inches) and then you seethat there are multiple flower heads on the stems.
Some of the leaves get a bit bigger as flowering continues, too, so the spread of the plant goes from around 16 cms (c 7 inches) to around 20cms (9 or ten inches) .
-
Maggi, I could live with that!!!
Btw, do you know what a young Campanula zoyesii looks like?
I have one tiny plant from seed obtained last year and would like to think it might be the real thing.
-
Didn't know plants could read, Darren.... ;D ;D
Thanks Maggi, Helen and Darren, this plant does seem to flower pretty well, though not always as well as it did that year. There are a fair few flowers on the plant this year but only one or two open as yet. The plant is in a crevice between blocks of sandstone, over which most of it drapes - hopefully nicely ripened wood!

The real thing will be covered in aphids and weevils & slugs will be lurking closeby at night. ;)

Then I suppose this isn't the real thing :'(
-
It's a lusty baby, Helen.
On that wonderful website... The Seed Site, there are now quite a range of seedling pictures a to complement the seed photos..... there is a tiny pic of Campanula zoysii seedlings there which doesn't enlarge, which is a shame. http://theseedsite.co.uk/sdg3.html
-
Maggi, first thought I had when I saw that pic is that it was one of my pics of campanula babies but have searched high and low and can't find the folder.
2009 I had around 16 different types of campanula seeds and took pics of all of the seedlings.
Thought I had posted them but can't find them anywhere.
Of course the pic might not be one of mine but it looks so familiar, maybe because the seedlings look like bluet babies.
Hopefully whatever my seedling is will flower soon.
-
I don't think yours is, Helen. The leaves are much too big and it tends to creep around right from the beginning. The pic on the seed site looks about right. On the other hand, the pic of C. chamissonis, I'm sure is NOT right. Looks more like one of the monocarpics or maybe even a Symphyandra. C. chamissonis is synonymous with pilosa, though there are different variants, some better than others.
-
Lesley, thanks for the input, at least whatever it is I don't think it will be invasive.
Hopefully someone will be able to ID it when it flowers which should be soon as it is in its second year.
-
Here's a pic of the potentilla flower.
It's finally decided to open.
-
That looks very like mine, Helen.
Was rootling around in the Archived Old Forum- as one does! and found this lovely close-up from Cliff Potentilla nitida rubra ( and of Dianthus superbus, re another thread!) ... it was here http://www.srgc.org.uk/discus/messages/4/15449.html
-
Helen re Camp. zoyszii we've tried it several times, it usually dies on the way home from the nursery ::)
-
Wonderful pic, Maggi, am still suffering vertigo after looking at some of the pics in that thread, especially the nightmare road.
Shelagh, still laughing from your comment.
Will be interesting to see what I have when it flowers.
-
A little late in the discussion but here are some pics of Potentilla hyparctica.

-
Thanks Trond... that's a nice link for all sorts of plants!
I'm thinking that my yellow is not hyparctica.... I have multiple flower heads whereas the Svalbard version has solitary flowers. :-\
-
Thanks for the link Trond, am pretty sure this is what my little plants are.
At least they look the same to me. :)
-
I have no idea what these potentillas are, but just thought I'd mention that P. hyparctica is one of the alpine potentillas that occurs here, and Flora of Alberta says the inflorescence may be one- or two-flowered.
Let alone suggest what the potentillas in question may be, I remain baffled as to how the various alpine potentillas that occur here are distinguished, and so I bought one at the local rock garden society plant sale last year, and grew another from seed, hoping to discern the differences as described in Flora of Alberta...
So, assuming whoever grew them or collected the seed actually knows the differences, the following species may be a couple more possibilities to consider for the potentillas in question here! ??? Or maybe for Helen's anyway, as these two don't form leafy stems.
P. nivea (a tighter plant but how much of that might be conditions?):
[attachthumb=1] [attachthumb=2]
P. uniflora:

-
Lori, thanks for the pics.
I have now decided to call my plants 'the little yellow potentillas' ???
-
I've had a chance to research Potentilla pulvinaris as suggested several pagers ago by Alan G .... seems not to be a fully recognised name, despite having been around since 1842 :-\
In the meantime, was looking at the plant with Roma today and Ian breezed off to check his photos with name labels and declared that the plant had come from Gerd Stopp as P. pulvinaris. ;D
