As a local, I've been to Balboa Park dozens of times over the past 20+ years. It's a place I thought I knew pretty well but life always surprises you. Something about this visit was a bit different. I noticed a colorful tree. You don't find trees with rainbow bark very often. I looked at it & all of a sudden I recalled news video I've seen earlier in the week. 

I watched a two-minute news clip about the rainbow eucalyptus tree, which stated that you can see it in various spots throughout San Diego County, including Balboa Park & the San Diego Zoo. There are tons of eucalyptus trees in San Diego but this was unique.

Just like most social media users, I absorb & consume a lot of content, so I thought it was cool but I never thought much of it. Fast forward to this one magical time I'm in the park. I saw the colorful rainbow eucalyptus tree & the video clip went through my mind. I took a couple pictures & moved on with my day exploring San Diego. That said, I cannot recall the exact geolocation but it was somewhere near the museum & building areas.

What Causes Rainbow Eucalyptus?

The little rainbow tree grows up to be a big rainbow gum tree. No no, just kidding. The rainbow tree effect comes from the various layers of bark as they begin to oxidize & peel off. Rainbow eucalyptus trees lose their bark & thus, shades of their color, which causes the stunning rainbow look. 

It may take years for a tree to acquire enough layering. You'll often see shades of orange & bright green. The trunk of this magnificent eucalyptus rainbow tree is a rare, seasonal sight. The best time to witness it might be in the springtime, that's when I viewed it!
