A few more blues from my garden. The Dracocephalum was labelled as tanguticum, but looks like ruyschiana so who knows. The Delphinium is D. kamaonense, then the common Phyteuma schutzeri and Codonopsis clematidae.
St. John's, Newfoundland, Canada
1800 mm precipitation per year
A nice blue quartet, Todd, regardless of what the labels say.
Rogaland, Norway - with cool, often rainy summers (29C max) and mild, often rainy winters (180 cm/year)!
Back from the Dolomites and over the jet lag. This picture of Horminum pyrenaicum seemed to belong in this thread. The only bad thing I've heard about it is that in the garden the ratio of flowers to leaves is poor. I grew this some years ago and didn't find this to be true. Unfortunately, it was killed due to neglect, but it is a very nice plant with wonderful leaves.
I grow Horminum pyrenaicum in my garden but the flowers seem to be smaller than on your picture. Have never been to the Dolomites, think it is a place to go one day!
Not true blue but a stout and huge plant where the soil is moist and rich. Used as a wolf-poison in earlier times hence the name wolfsbane.Aconitum septentrionale is very common in low alpine and at the treeline.
Snøsøte ("Snow sweet", Gentiana nivalis) is the bluest flower in Norway. Not uncommon in the alpine zone you do not notice the tiny plant if the flowers are closed. They open only in sunshine above 10C.
That nivalis is intense! It is also native to Newfoundland but only in the most northern areas of Labrador, in areas too remote to ever be visited!
Terrific stands of aconitum!!
Calgary, Alberta, Canada - Zone 3
-30 C to +30 C (rarely!); elevation ~1130m; annual precipitation ~40 cm
Not for the rock garden though but very blue.... and the red not-fertilized seeds of a peony.
This is a Hydrangea macrophylla-hybrid of unremembered name.
That is a very beautiful hydrangea.
1) Here's Eritrichium canum var. canum, which was received last year in a mislabelled seedex packet, and has since proved itself to be a pleasant addition to the garden. It seems to act, so far, as an annual here, though it is said in the following account to be a perennial.http://www.efloras.org/florataxon.aspx?flora_id=5&taxon_id=250084608
2) Gentiana septemfida, one of the few plants flowering in the troughs here lately.
