Color is certainly subjective. I find it interesting in the Flora of China, not sure if it is a translation issue or not, that pink flower color is invariably listed as "pale red". Going back to Antennaria
, for most of the deeper color forms of A. rosea
and A. dioica
(including the nice one you show Trond) I would call them pink; a nice bright or rich pink, but definitely pink. There are some selections that, repeating my previous characterization, "approach" red.
I think the genus Penstemon has some interesting cases, such as with the shrubby Dasanthera species, where flower color traverses the pink to red spectrum. I hear people describe the flowers on Penstemon rupicola
as red, or "cherry red", but to me they are definitely a rich pink. http://calphotos.berkeley.edu/cgi/img_query?enlarge=0000+0000+0809+1902Penstemon newberryi
has several forms, often the flowers are a rich intense pink, or "rose-red", but there are some true pure red flowered forms. Bob Nold's book on Penstemon mentions a cultivar of P. newberryi
named 'Red Lassen'
offered by Siskiyou Rare Plant Nursery; a cherry red selection. I once grew a form of Penstemon newberryi ssp. sonomensis
from seed that had amazing blood red flowers, not pink in the slightest. Googling around, I found another cultivar at Yerba Buena Nursery named Penstemon newberryi sonomensis 'St. Helena'
The CalFlora site has some nice photos Penstemon newberryi ssp. sonomensis
, they look decidedly red. The subspecies is notoriously fussy in cultivation, but who wouldn't want to grow this beauty.http://calphotos.berkeley.edu/cgi-bin/img_query?rel-taxon=contains&where-taxon=Penstemon+newberryi+var.+sonomensishttp://calphotos.berkeley.edu/cgi/img_query?enlarge=0000+0000+0509+2901
