I had this for several year as a pot plant. I am sorry it is not reliably hardy here.
Rogaland, Norway - with cool, often rainy summers (29C max) and mild, often rainy winters (180 cm/year)!
In the garden of a friend of mine (Marsha Russell), she had scads of Anthyllis vulneraria coccinea; what an eyeful of blazing red color :o :o. I'm not sure about the true name of this color form, I have seen it listed as rubra and coccinea, but these must be illegal latinized cultivar names, because even though there are scads of varieties of Anthyllis vulneraria, I don't find a var. or ssp. coccinea anywhere. Marsha pulls out most of them each year, otherwise they'd probably take over the garden, but not to worry, they always come back from abundant self-sown seedlings.

Anthyllis vulneraria is common on sandy soil many places in Norway, even in the mountains. Usually it is yellow or orange. I have never seen reds in the wild but I know the subspecies A. v. ssp vulneraria can be red. I grow both the red and the yellow form at my cabin in the mountains.
Here are some of my red flowered plants for the moment:1) Lewisia cotyledon-hybrids are very popular here and seem to tolerate the winter wet. with reasonable drainage.2) Phygelius capensis is often evergreen except the worst winters.3) Rhemannia elata is monocarpic. It often flowers first year from early sowing but unflowered rosettes flower next summer.
Nice, Hoy! I was very disappointed that Rehmannia glutinosa, supposedly very hardy (re. Rix and Phillips), did not winter over here for me.
This is decidedly orange, but it's the best I can do right now... Penstemon barbatus coccineus:
Calgary, Alberta, Canada - Zone 3
-30 C to +30 C (rarely!); elevation ~1130m; annual precipitation ~40 cm
The Penstemon barbatus coccineus is red enough for me!
My contribution this time is not a flower but a kind of fruit, the unfertilized carpels of Paeonia mairei, here together with a Geranium sp from Himalaya.
Fruit! I can contribute with that...
Rick Rodich zone 4a. Annual precipitation ~24 inches
near Minneapolis, Minnesota, USA
How about a South African? Romulea sabulosa, can be grown in the ground here but I keep them in pots because of the cockatoos which have developed a taste for the corms!cheersfermi

This one was red! Looks a little like some tulips I have. Romulea don't do well here, too moist.
Here's the best I can do - not an alpine though - Silene regia, starting to bloom.
