Well, I think they are asters….
In areas with relatively high altitude, plant communities in Costa Rica are quite similar to those found in Ohio. Many of the species found in these areas belong to the same genera that dominate plant communities here. For instance, Quercus-dominated (oak) forests are present just below the tree line in Costa Rican mountains. In fact, I believe there are just over 20 species of Quercus, and at least one of which is endemic (e.g., Quercus costaricensis). Vaccinium (blue berries) can also be found mountainous areas, but the berries aren’t quite as delicious.
