We have two Rocky Mountain Bristlecone Pines on the west side of our yard.
p>The north one is the largest. I estimated its height on 3 Sep 24 to be 7.5 meters and diameter at breast height of 19.4 cm.
The pollen cones are between last year’s and this year’s growth, and are on almost all of the lower branches. The seed cones are higher up.
Pollen Cones
New first-year seed cones are small and blue with relatively long bristles.
First-year seed cones
Second-year cones are brown, longer, and often covered with sap.
Second-year seed cones
Needles (according to Bonzai Tonight) are long-lived, up to 20 years.
