After the species mentioned above survived two of the colder winters outside in the 'bog' I guess it could be stated a hardy perennial. This fact is poorly known and somewhat surprising because of the origin of the plant. Haplocarpha rueppelii comes from the mountains of tropical East Africa.
The preference for wetland conditions was already discussed in this Forum.

No denying those plants look very healthy, Gerd. Wonderful what a little experiment can reveal, isn't it?

I wonder where precisely the cultivated strain was collected. I found a record Haplocarpha rueppelii <ln Lesotho>.
Leaves are too narrow for Haplocarpha rueppellii, backwards oriented basal lobules are not present
in Haplocarpha rueppellii in which radially oriented lobules are evenly distributed along the margin.
There is a gardening wisdom which follows.
If you are cultivating without problems a plant which is not cultivable,
it is not the plant.

Yes, it would be interesting to know that and to see how wide the range of the plant is.... all of which might impact on the hardiness if different strains.
I see that Franz Hadacek has no problems with it, either........

Should there be an extra "l" in the name.... ???
Haplocarpha rueppellii (Sch.Bip.) Beauverd
-

Haplocarpha rueppellii (Sch.Bip.) Beauverd
One l for Beauverd, two for Sch. Bip. are written in Plant Names Index. I cannot guess at the moment which is correct.
Probably ruppellii without e because it was published rüppellii and published accents ought to be removed.

My Haplocarpha rueppellii was hard until this winter. In spite of a snow cover, I lost 90 % from my plants.

Oh dear, I spoke too soon, Franz. I was thinking of the lovely pictures on your website from previous years.

Franz, it is exactly your clone I am talking about. Here ' in the north ' the plant is perfectly hardy and happy in boggy conditions - it seems that is the point!
There exists an information from the nursery of Dr. Hans Simon concerning the species which stated ' Felssteppe ' = rock steppe and 'trocken' = dry.
This is misleading because the plant is found in East Africa in wetland conditions.
I would be glad if you could tell something about the source of your plant?

Gerd,
I a so sorry, I do not know exactly , from whom I got these plant. I think I got it from the Nursery Kress.
By the way I cultivated the plant more dry. I think my plant am dried. We had a very long frost period.
-
Franz, no reason to apologise!
We also had a long period below zero - the plant, growing in frozen soil/water at the edge of a small pond survived without showing any harm. In summer it sends runners which float on the surface of the water. A quite unusual and interesting alpine!

It may be that my memory is letting me down - it wouldn't be the first time - but I'm reasonably sure this is the plant which I brought home from an English nursery around 30 years ago and within a couple of years it had covered an area of square metres and in the end had to be treated with Roundup. The roots were like leathery spaghetti and hard to get them all out but the rosettes multiplied with the abandon of the field thistle Circium arvense. Low of course.
-
Lesley,
Concerning the spreading habit and the description of the roots it seems you 'cultivated' this species - thanks god here in our conditions a little bit tamer.

Resembles Arctotis hirsuta alias Venidium hirsutum
http://www.aluka.org/action/showPDF?doi=10.5555/AL.AP.SPECIMEN.K000307347&type=img&pgs=
but differs. There are non-described Arctotis in Lesotho.

Haplocarpha rueppelli is not from Lesotho, but from the mountain regions around Mt.Kilimandscharo.
The plants from Lesotho are different, their name is H. nervosa. A group of Czech botanists collected
these plants some years ago and I was lucky to get one of these and it is fully hardy with me.
In Lesotho it forms extensive mats in marshy places up to 3000 m.

The plant cultivated as Haplocarpha rueppellii is certainly not Haplocarpha rueppellii
but a completely different species and probably not a Haplocarpha at all.
Haplocarpha nervosa introduced by HKV expedition is a weedy nuisance.

In Haplocarpha rueppellii leaves are broad, without basal backwards oriented lobuli,
and midribs are not hairy. Forget about Kilimanjaro and tropical East Africa.
The cultivated plant is certainly a Drakensberg dweller.

Gärtnerei Simon alleges locus natalis Lesotho for Haplocarpha rueppellii. I wrote there in my bad English but without reply. My German is yet worse. Perhaps German members might be successful if asking about the origin of the information in Gärtnerei Simon.

Has anyone positively identified this plant? My plant came from Zdenek Rehacek in 2009. His plants are covered by snow for many moths
Mine survived the extreme cold of December 2010 but did not flower this year. They are growing in very gritty sol under a Betula. Maybe I should move some
The first two photos are of Zdenek's plants. The last photo shows mine
-
Maggi would you like a plant?
-
Maggi would you like a plant?
I would very much like one, Mark, yes, please! :-* :-*
I'm still not sure about the ID.... those leaves on yours are quite fancy shaped compared to some photos I've seen of the plant, where the leaves appear fairly plainly shaped and without much in the way of a petiole.....:-\ :-\ :-X

I found this thread today ;D
Can anyone confirm that this is a Haplocarpha? And which one? Found on Mt Kenya 3500m. The ground froze almost every night.

Nice looking plant.
Maggi I think some of the leaves on my plant stretch to reach the light. I'll pick some tomorrow to show the variation

Trond, that is just what I think Haplocarpha rueppelii should look like... and Mount Kenya is the perfect place to see it .
The leaves are entire and rather heart- shaped .... a bit like a shiny Ramonda!
-
and thats what I see when I google Haplocarpha
5 people in Plant Finder are selling Hapolocarpha reupelii. I'll phone them tomorrow and ask about their plants.

Thanks Maggi :D
Then I call this one Haplocarpha rueppelli - and have only about 20 unknown left ;)
(Here's a better copy)

Mark, the places under the birches are usually rather dry and the Haplocarphas prefer moister places
during the growing season.
I am sure that moisture and fertilizing will support flowering. Good luck!

I wonder whether you brought solely the image or an offset or seeds too.
It might be interesting to check the hardiness of equatorial plants
in European conditions.

Sorry, no seed or offsets. I did not find ripe seed and as this was early on the journey I decided not to take offsets or anything else a decision I regret today. It was quite common in several places on moist soil.

In my garden was Haplocarpa not hard.

We acquired this plant from Nigel Clutton who has it growing on his natural rock garden on the coast of NW Sutherland. Fairly sure it is this species though he had no name for the plant. Apart from the distinctive leaf form and its spreading habit, the only other distinguishing feature was the bright yellow 'daisy' flowers. The offset he gave us overwintered through a moderately hard winter, made a single flower in Spring, and then set off to take over quite an area of the garden. In three months it has multiplied to 30+ rosettes each two or three inches apart. The foliage isn't really very attractive and the flowering was brief so I suspect it will have to go.
