This is my first year as well, and I have two plants - chinook and centennial. The centennial is very healthy/bushy but short (only about 5 ft), and the chinook is over 20 ft and still going! Both have little flowery-bud-like-poof-things ALL over... are these what you guys are referring to as "burrs"? Are these what turn into cones? Can I expect any cones this year (very long summers in Idaho)?
