I have had Vulcan Logic several years. Lovely bloom, so-so bud count. It has had an occasional good year for bloom, but has not grown significantly since I got it. In its defense, it may not be in the best location, but daylilies beside it do fine.
A distinctive coloration on this bloom. Plant has been reasonably vigorous, though I don't remember how many years I've had it. Bud count this year was in teens (quite acceptable for here), though not on every scape (isn't that always the case?). I can remember an off year, but not this year (when many were off).
