After a trip to Yosemite in Summer of 2012, I caught a "sequoia bug". I am attempting to grow my own sequoia from seeds. These sequoias (Sequoiadendron Giganteum) will be grown in Iowa, which is Zone 5, a harsh environment for sequoia.
Here is a picture showing two varieties of sequoia side by side.
The two on the left are standard sequoiadendron from seeds. The one on the right is “exceptionally blue” clone from Crowfoot Nursery. The difference in color is pretty striking.
