As we wrap up another year of observations, let’s take a look at what observers have reported through the Cloned and Native Flowering Dogwoods Campaign!
Your observations of dogwood life cycle events help build on decades of phenology records collected across the U.S. through the Cloned Plants Project. By comparing native and cloned flowering dogwoods, we can better understand how genetics and environmental conditions influence the timing of plant development. Observations of native and cloned trees at the same location are especially valuable, helping us tease apart these influences and better understand how plants respond to their environment.
Slide 2 shows a map of where and when native and cloned dogwoods flowered across the U.S. this year.
Slides 3 and 4 show activity curves highlighting the timing of flowering and leaf growth in dogwoods across the country. Data collection for this campaign began in 2019, so these slides compare seven years of campaign data. Overall, the patterns have remained consistent over time.
Slide 5 highlights the top Local Phenology Programs contributing to this campaign in 2026. Thank you all so much for your continued efforts and contributions!
