Went and saw Iseli rep talk at a local garden center. Iseli is located east of Portland, OR - plants discussed were being grown in display garden and container production operation in that environment. Handout lists and describes these:

*Apparently inadvertantly skipped over during the talk

Some specific points that stuck with me:

They have a 'Sekkan' in the display garden there he thought was about 40' tall

He claimed the 'Donard Gold' was quite hardy

The 'Skylands' shown somewhat resembled the yellow mystery spruce asked about on another thread here, where 'Skylands was suggested as a possible identification

He said when they first started propagating 'Chief Joseph' they had low percentages because they were doing pines during the winter, when that variety is low in chlorophyll - I heard no followup comment indicating what, if anything was done to overcome this

'Taylor's Sunburst' was said to look poorly except when in new spring growth
