Beautiful plant, Peter! I love the brilliant orange... especially against the electric pink! :D Delightful!
My little plant is safely ensconced inside the fence now and seems to be confirming itself to be C. parviflorum (though today's lashing rain is delaying the bloom).
Calgary, Alberta, Canada - Zone 3
-30 C to +30 C (rarely!); elevation ~1130m; annual precipitation ~40 cm
I would say almost the same as Lori: Beautiful plants ;)I have many colour crashes in my garden as I try to put plant in accordance with growing requirements rather than colour.
Rogaland, Norway - with cool, often rainy summers (29C max) and mild, often rainy winters (180 cm/year)!
Okay, case closed, I think!
I would love to find such weeds ;)
